Background
Scope
New spatial data, tools and technologies are enhancing and streamlining
transportation program delivery activities in many parts of the country.
The TRB Committee on Statewide Data and Information Systems hosted a peer
exchange to identify the kinds of spatial data tools and information that
are most effective in delivering multi-modal transportation programs. The
optimum use of these tools in identifying and prioritizing programs, and
in improving program delivery was also explored.
Results of the exchange provided findings and insights into
what kinds of spatial data, information, tools and technologies can yield
the most value and benefit in terms of improving transportation planning
and program delivery processes for transportation agencies.
Sponsors
The peer exchange was organized by the Statewide Transportation Data &
Information Systems (A1D09) and the Data Task Force of the AASHTO Standing
Committee on Planning. The Federal
Highway Administration Planning and Environment provided funding.
Participants
Invitations were extended to members of the TRB Committee on Statewide Data and Information System and other participants who are involved or interested in implementing spatial data tools and technologies to operate, manage and improve transportation programs within their agencies and departments. The following is a listing of peer exchange participants:
Format and Topics The peer exchange program included three opening presentations highlighting the role and value spatial data, tools and technologies offer. Subsequent group discussions and brief individual state presentations focused on: § Specific examples of where new spatial data, tools and technologies have led to improved decision making, streamlined program delivery activities and/or more comprehensive analysis of modal choices and alternatives. § Issues associated with the implementation of new spatial data tools and technologies, including those associated with integrating data with different scales and resolutions. § Effective uses and applications of nationally available data sets.
§
The role of remote sensing and other emerging spatial data technologies. Results of the peer exchange
provided insights into what kinds of spatial data, information, tools and
technologies can yield the most value and benefit in terms of improving transportation
program delivery processes for transportation agencies.
Each state DOT representative was also requested to answer five questions
as part of their presentations.
Questions One through Three focused on program development and delivery
since previous committee activities had emphasized the critical impact of
spatial technologies on the delivery and use of transportation data for program
decision-making. The five questions
are as follows:
1.
What are some of the key issues affecting program delivery in you state
or agency? For example, what
factors are contributing to the delay of projects and programs?
2.
How are information and new spatial data, tools and technologies helping
you address the issues and factors?
3.
Are there one or two specific examples where spatial data, tools and technologies
reduced program delivery timelines, facilitated consensus on project or program
alternatives or enhanced program delivery in other ways?
4.
What barriers or constraints have you encountered in gaining support for
spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
5.
What do you believe are the critical pieces that must be in place to ensure
success in this area?
Introductory Remarks
Ron Tweedie, facilitator of the peer exchange and past-chair of TRB A1D09
Statewide Transportation Data Committee, welcomed the participants.
He reiterated the purpose of
the peer exchange to identify optimum use of spatial data tools and information
to facilitate decision-making and to deliver multi-modal transportation programs.
Key groups represented at the
peer exchange are the AASTHO GIS for Transportation Task Force, the AASHTO
Standing Committee on Highways Spatial Information Task Force and the Standing
Committee of Planning Data Task Force.
The peer exchange started with presentations by upper-level administrators
directly managing program development activities.
Subsequently, representatives from state DOTs presented a
synopsis of their spatial analysis activities.

State Transportation Planner, Florida Department of Transportation
Freddie Simmons, State Highway Engineer, and Ysela Llort, State Transportation
Planner, for the Florida Department of Transportation, presented their perspectives
as upper-level administrators on the use of spatial analysis tools in program
delivery.
1.
What are some of the key issues affecting program delivery in
you state or agency? For example,
what factors are contributing to the delay of projects and programs?
·
Reduction in resources
·
High number of assets
·
Escalating preliminary engineering cost
·
Delays caused by “scope creep”
·
Changes in technology
·

2.
How are information and new spatial data, tools and technologies
helping you address the issues and factors?
Florida DOT is primarily using two new tools: Geo-Referenced Information
Portal (GRIP) and Florida Geographic Data Library (FGDL).
These tools provide solutions to most of the key issues addressed
in Question 1. They are breaking
down integration barriers, facilitating dissemination of data to multiple
users, and providing necessary management tools for all phases of project
development, delivery and operations
3.
Are there one or two specific examples where spatial data, tools
and technologies reduced program delivery timelines, facilitated consensus
on project or program alternatives or enhanced program delivery in other ways?
GRIP provides such data on a corridor as work program information, pavement
conditions, video logs, crash data, traffic counts, aerial photography, contour
maps, structure information, plus all types of other information.
FGDL provides hundreds of data layers gathered from many state, federal,
and local agencies. These includes
elements such as tax maps, aerial photos, wetlands, census information, endangered
species locations, vegetation types, historical sites, airports, rail corridors,
traffic data, hospitals, flood plains, and hundreds more.
Both of these tools are now used by FDOT as planning and project development
tools and in work program development

2. Washington Department of
Transportation Perspective
Charlie Howard,
Director, Planning and Policy Office, Northwest Washington Division, Washington
Department of Transportation
Charlie Howard, Division Director of the Planning and Policy Office for
the Washington Department of Transportation presented a comprehensive overview
of the implementation aspects of effectively incorporating spatial analysis
technologies.
1.
What are some of the key issues affecting program delivery in
you state or agency? For example,
what factors are contributing to the delay of projects and programs?
Key Issues
1)
Lack of funding, which is tied to public perception of our effectiveness,
efficiency and accountability and our ability to convey our needs in a way
that appeals to the public.
2)
The length and lack of certainty in environmental review processes
2.
How are information and new spatial data, tools and technologies
helping you address the issues and factors?
1) GIS and spatial data provide a means of creating a graphical representation
of our program. Maps combined
with images help us make our case for doing the right things by showing where
new funding will be applied to meet program needs.
This has proven to be an effective means of communicating
complex program with the legislature and citizens.
2) Maps generated from spatial data are included in web based project summaries
as a communication tool with the public.
The map plays a key role in public perception that funding is
being put to good use as they can see what we are doing and where.
http://www.wsdot.wa.gov/eesc/environmental/programs/envinfo/envinfo.htm
and
http://www.wsdot.wa.gov/projects/
(navigate to specific
project pages from there.)
3) Spatial data and GIS tools provide a means of helping us do the right
things through planning and project scoping.
Complex combinations of data from disparate sources can be
integrated in the GIS environment to assist analysis of needs and scoping
of solutions. The result is better
decisions because data relationships are more apparent in the graphical view.
4) GIS and remote sensing based information and technologies are increasingly
available and used by our consultants doing Environmental Impact Statements
for transportation projects.
This has allowed better information to come to the project planning process,
earlier in the design.
5) Web-based GIS is being used to encourage and identify mitigation partnerships
where beneficial environmental work has been defined.
The Uniform Environmental Project Reporting System shows WSDOT
project locations and environmental restoration, clean up, protection, or
enhancement projects have either been funded or proposed for funding.
This can be used by transportation projects to find locations
for mitigation that have been defined and have existing support that can make
mitigation negotiations and site design go better and faster
www.ueprs.wa.gov
.
6) We are investigating the application of satellite imagery and remote
sensing technologies such as LIDAR to environmental assessment.
A pilot project has begun on I 405 through a USDOT grant.
The project will evaluate the quality of data and cost benefit
of remotely sensed data in comparison to data traditionally used in NEPA analysis.
3.
Are there one or two specific examples where spatial data, tools
and technologies reduced program delivery timelines, facilitated consensus
on project or program alternatives or enhanced program delivery in other ways?
1) Maps prepared using spatial data and tools have been effective in communicating
with the governor, legislature and the public.
These communication tools have helped develop consensus that
we are doing the right things.
2) Spatial data and tools have been applied in the corridor planning process
to overlay design elements on digital orthophotos.
These are used to clarify the feasibility of alternative solutions
and to display the results with a real world reference.
We have a specific example from the SR104 EIS where these
tools helped the project stay on schedule.
3) Priority Array Tracking System GIS (PATS/GIS) provides a means of analyzing
system needs in a spatial environment.
4) Maintenance has created spatial inventories of work items for managing
operations. Polygons identify
landscape maintenance needs such as mowing, spraying, etc.
Point events identify catch basin locations.
These inventories are used to identify resource needs to maintain
level of service and to manage operations.
5) ITS web applications such as the WSF Vessel Tracking system and Traffic
and Weather pages use spatial data representations to provide information
to travelers and/or to assist travelers in finding information about a given
location. The WSDOT web site
provides information on ferry locations, traffic surveillance cameras, weather
conditions, road conditions, etc. through map interfaces
http://www.wsdot.wa.gov/
ferries/commuter_updates/vesselwatch/.
6) The Monuments database is a web-based application to provide access to
the WSDOT survey control network.
WSDOT, local agencies, and private surveyors heavily use this database.
The net result, while incremental, shows improvement in coordination
between agencies achieved through common survey control.
http://www.wsdot.wa.gov/monument/
7) Environmental review summaries as part of project summary are supported
by a custom GIS application that facilitates access to over 70 GIS and remote
sensing based information themes collected from federal, state, tribal, and
local organizations. The availability
of this information and tool has improved the time it takes to complete project
summary by reducing research time and targeting field time.
While the time required naturally varies by the nature of
the project and the location, it was shown that using this spatial technology
tool to complete an environmental review summary reduced the time required
by up to six hours. Additionally,
the tool has promoted the statewide consistency and completeness of these
reviews, generally improving the overall project definition, cost and schedules

.
4.
What barriers or constraints have you encountered in gaining
support for spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
1)
Training and implementation
: It is hard to keep staff up to date and interested in learning to use
the technology, especially when technology is changing at the pace it does.
For example, both GIS and CAD data can be viewed with either technology,
but many users have not had time to learn that that is now fairly easy if
certain standards are used.
2)
User-friendly applications
: Technology solutions that
are easy to use and do just what you need are time consuming and expensive
to put into place on an enterprise scale.
Some limited success has been achieved for targeted
applications such as for the Environmental Review studies.
The cost and limited application has us looking at more general
solutions that provide the same user-friendly characteristics.
3)
Funding for data development
: The funding to collect and build geo-spatial data like orthophotography,
needs to be available during the earliest phases of project design.
4)
Interagency coordination
: Interagency coordination, cooperation and funding for geo-spatial base
data used to integrate data across agencies is challenging.
Cooperative funding efforts often go awry when competing with
individual agency priorities.
This is sometimes overcome when the data logically supports a statewide
or national governmental issue like salmon recovery or homeland security.
5)
Business relevance
: The best way to get resources
for any technology effort is to prove to key beneficiaries that the product
will improve their ability to do their job and meet their goals.
Too often databases are built without the end user in mind.
As technologies evolve, such as remote sensing and GIS it is unclear how they
relate to transportation and so we wait.
Demonstration projects are needed to add value for the transportation
community.
6)
Comfort with existing tools
: DOTs have historically met
their business needs using CAD and CASE.
As we redefine the policies for transportation and integrate
issues such as context sensitive design, congestion relief, and watershed
approaches, the need for data on the larger landscape becomes more relevant.
However, a barrier between software users still exists.
5.
What do you believe are the critical pieces that must be in place
to ensure success in this area?
1)
Easy access to base data
: Accessibility involves access to the software and data, tools to facilitate
use of the software and data, training, and technical support.
Accessibility is facilitated by standard location references
to allow pulling together data from many sources.
Keys to successful data accessibility include:
training in the use of standard location references, identification
of data stewards with assigned responsibility for maintenance of location
references, policy that demands adherence to location standards, and enforcement
of the policies.
2)
A data clearinghouse
: A collection of base data
including geo-referenced imagery, base maps, needs inventory, facilities inventory,
... together with metadata that
describes it.
3)
Interagency cooperation
: Cooperative partnerships
between agencies to pool resources to develop better, more accurate data
than can be done individually.
Washington State is pursuing this through the National Spatial Data Initiative
framework data theme development.
Development is underway for Cadastral, hydrography, transportation, and geo-referenced
imagery. A committee of executives
is forming to facilitate implementation of cost effective, collaboratively
developed spatial data management solutions.
4)
System hardware
: Adequate I/T infrastructure
to support spatial data tools.
This includes standards for software, standards to define how to access
software and data, network and server resources to handle large volume spatial
database, especially images.
5)
Regulatory applicability
: It is unclear whether regulatory
and funding agencies accept the resolution and accuracies for funding and
permitting decisions. Further
clarification could facilitate additional willingness to fund and support
spatial data applications and technologies.
6)
Funding:
Federal and state agencies need to clarify when, where and
how it is appropriate to funding data and application development.
Should specific spatial technologies be identified through
reauthorization? Should information
technology funding be specifically identified?
7)
Pilot projects
: We continue to support the
National Consortium on Remote Sensing in Transportation.
These pilot projects are instrumental in helping the
transportation community continue to evaluate the use of new and emerging
technologies. We are staring
to see the analysis and cost benefit assessment from these projects.
3. Overview of Trends on the
Value of Data
Stacy Fehlenberg
, Environmental Scientist, United
States Environmental Protection Agency (USEPA)
Stacy Fehlenberg’s presented a description of the inter-agency efforts to
streamline the NEPA process regarding the I-69 project. I-69 is an interstate
highway that was written into the Congressional TEA-21 Transportation legislation
to connect the major U.S. centers, leading economic border crossings, the
largest seaports, and the growing air freight corridor from Canada to Mexico.
She focused on the impetus for the effort, how the efforts
were accomplished using spatial analysis, and how the participants are measuring
success.
Key issues affecting the NEPA process were lack of early communication and
coordination between the transportation and resource agencies. This lack of
communication stems from the traditional method of planning transportation
projects that invested vast amounts of time and energy into developing proposed
alignments before considering environmental impact. By the time resource agencies
saw the Draft Environmental Impact Statements (D/EIS), whatever concerns
they may have and however accommodating the DOT may want to be, it was often
simply too late to make major adjustments.
By sharing information on ecological issues during the pre-planning phases,
both types of agencies had the opportunity to coordinate their priorities
while there was still time to affect them. This gave the resource agencies
the chance to present their concerns to the DOTs while there was still time
to consider them, and it also afforded the DOTs a chance to know the resource
agencies’ concerns before investing heavily in a plan that would be objectionable
to them later. This process streamlines the NEPA process in that there are
fewer surprises for the resource agencies during NEPA review, and hence less
time and money spent trying by the DOTs to accommodate their concerns. This
saves both types of agencies time and money.
It was decided that this information sharing would be done via a GIS database.
A spatial database could best compile, analyze and present multiple agency’s
data in a single, meaningful, interpretable database. The greatest constraint
to this effort was lack of consistent, quality data in digital format. Another
constraint could have been time to develop a methodology to analyze all
the data, but fortunately, an appropriate one had just been developed. Also
lucky was the availability of a GIS lab and the human resources needed to
conduct such a large-scale analysis.
The critical components to make this effort work are avocation from top
management on both sides, specific action plans, and the designation of a
single agency and single person who was responsible for the production of
the product. There were some steps that could have been taken to further
secure the project, and lessons learned as well as successes.
One specific example of the success of this project is the routing around
the Tahomey National Wildlife Refuge in NW Mississippi. The maintenance of
a wildlife corridor between the refuges was considered vital to all resource
agencies that worked in the Delta, and its disturbance would have raised considerable
objection from the reviewing and commenting agencies. By sharing the areas
of ecological concern with the DOTs and their contractors early on, the bisecting
of the Tahomey from the White River NWR was avoided.

safety, congestion, mitigation and environmental streamlining.
5. Texas Department of Transportation
Kim Hajek,
Director of Data Management, Texas Department of Transportation
Kim Hajek presented Texas DOT’s perspective of the use of spatial tools
in program delivery. Currently,
Texas DOT annually submits the Unified Transportation Plan (UTP) to the Texas
Transportation Commission. The
UTP includes projects scheduled for the current calendar year and three additional
years. The current value of the
UTP is $12 billion, approximately $3 billion a year over four years.

Kentucky Transportation Cabinet
Rob Bostrom,
Transportation Engineering Specialist, Kentucky Transportation Cabinet
Rob Bostrom’s presentation focused on the organizational aspects regarding
the application of geographic information system technologies.
Kentucky Perspective
This perspective includes, (1) some background on Kentucky’s organizational
approach to GIS and spatial data and (2) a response to the five questions
identified by TRB for the Peer Exchange.
Responses to questions are from three different groups: the Division
of Information Technology, the Programming Branch and the Division of Planning.
The source of the responses is shown in parentheses after the
paragraphs below. Kentucky
GIS Organization GIS Office: Works out of Governor’s Office of Technology (GOT). See web site at: http://ogis.state.ky.us/ . Transportation Cabinet: Division of Information Technology. A group of three people are in charge of software, documentation, supporting files, training, etc. for GIS. They are also in charge of the Highway Information System (HIS), which is the Oracle database for data going into GIS. It includes more than 300 attributes and will go to EXOR this fall). User manual describes system in great detail. Transportation Cabinet: Division of Planning. In charge of creating the GIS base maps. The base maps are 1-meter accuracy based on GPS work done by the local Area Development Districts. This division is in charge of HIS data collection and GPS data collection and is responsible for quality control. Guidelines for GPS data collection are attached. Transportation Cabinet: Division of Programming. In charge of the Cabinet’s Six-Year Plan which is the “Bible” for scheduling and tracking projects. This division has an Oracle database that is used heavily for GIS inputs. They have been a leader in GIS applications for the Cabinet. There are approximately 140 GIS users in the Cabinet and every division now uses spatial data. The district offices are also starting to use GIS. The Cabinet’s consultants make heavy use of GIS.
1.
What are some of the key issues affecting program delivery in you your state
or agency? For example, what
factors are contributing to the delay of projects and programs?
Key issue affecting the program delivery is delays in project schedules.
These delays are due to a number of factors, including: overly
optimistic original project schedules, delays in project delivery due to
environmental issues, and shifting personnel to higher priority projects.
(Programming)
Inefficient distribution of information is still a problem.
For example design changes are made in a road alignment.
This adjustment moves the alignment outside of the areas evaluated
for environmental impact. Without effective information flow back to the Environmental
Division, the project is stopped for reevaluation later when the realignment
is discovered. A centralized method of sharing spatial information (GIS)
would mitigate against this.
Lack of complete statewide information (Information Technology)
2.
How are information and new spatial data, tools and technologies helping
you address the issues and factors?
We are bringing more and more information into GIS so that people can quickly
evaluate and make more informed decisions. For example the archaeologists
now have GIS tools so they are saving between one half and two days work in
preparation for projects as compared to the past.
The use of GIS can quickly identify where data gaps occur. (Information
Technology)
We have GIS capabilities to link real time data from Oracle Preconstruction
Project Status System, and this information is used for management reports,
public presentations, and internal project tracking.
(Programming)
3.
Are there one or two specific examples where spatial data, tools and technologies
reduced program delivery timelines, facilitated consensus on project or program
alternatives or enhanced program delivery in other ways?
The high profile corridor project I-66 has used GIS heavily (see report
on web at: http://www.kytc.state.ky.us/planning/I-66%20report/I-66er.htm
). GIS was used to help build mapping to facilitate public meetings and
discussion.
Planning has also moved to GIS based mapping (see web at:
http://www.kytc.state.ky.us/planning/gisourky/index.html) and this
is greatly increasing their efficiency in map productions so they are able
to shorten the cycle between major mappings of information.
Program Management is also using GIS to help build the Six Year Plan (see
web at:
http://oraweb.kytc.state.ky.us/sypbook/owa/swb$.startup
).
Planning has used GIS successfully for the long range (20-year plan).
See web at:
http://www.kytc.state.ky.us/planning/STP.htm
. (Information Technology)
The use of new technologies provides the means of preparing several preliminary
alternate alignments for projects, which can be quickly analyzed to determine
relationships to environmental concerns and preliminary roadway quantities.
This provides with the capabilities to review more alignments
and help identify major concerns earlier in the planning phase. (Programming)
Other examples of GIS usage include traffic models using TransCAD, Census
Support/TAZUP using Maptitude, corridor studies, and map display (such as
count maps that are copied from GIS to PDF e.g. see:

)

What barriers or constraints have you encountered in gaining support for
spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
The biggest challenge is cultural. Many people fear change. If you can show
the users how their jobs will be easier or better, then most will accept it.
The Cabinet has a clear commitment to capturing spatial data. The real challenge
is in building it so that it is sharable enterprise-wide.
There is also a high learning curve associated with these technologies.
We have to help guide and train the users so that the technology can be more
easily incorporated into their work process. (Information Technology)
Our constraints have not been from lack of new resources and technologies,
but has come from the lack of “buy in” from the project managers to keep project
information updated in our Oracle Preconstruction Status System.
Having the GIS capabilities have helped convince the project
managers of keeping data updated, because they are seeing exhibit maps and
reports being provided to management personnel.
(Programming)
5.
What do you believe are the critical pieces that must be in place to ensure
success in this area?
The individual agencies need to be better informed about the “big picture.”
We are constantly making decisions to create a “quick-fix” that ends up creating
more work in the long run than if we had taken a more enterprise approach.
(Information Technology)
We must ensure that our employees stay current on new technologies, by providing
required training and new software/hardware.
We must let our employees “think outside the box,” so they
will develop new and better ways of doing their work, which will help us in
the overall project and program delivery.
(Programming)
Management support
.
Historically, data collection has been viewed as a necessary task, but a
less important, sideline activity that can be done by under utilized, under
trained, staff who are also perceived as less than important.
This has changed in recent years as a result of the Cabinet
putting a higher priority on data collection, GIS, GPS, and other related
activities.
Resistance to change or build shared systems.
In the past, data collectors themselves have been reluctant to implement
new techniques or technology.
"We've always done it this way" is still heard.
Ownership has been fragmented since each of the 12 districts
has a unique way of viewing or addressing data needs. This mindset has been
eroding away over the past few years.
Middle and upper management understand the need for data for
accountability, to gauge the performance of the highway system, and ultimately
improve the highway programming process. (Planning)
7. Maryland State Highway Administration
Bill Walsek,
Chief, Highway Information Services Division, Maryland State Highway Administration
Bill Walsek presented Maryland’s perspective on the application of spatial
technologies and developing an agency-wide spatial resource.
1.
What are some of the key issues affecting program delivery in your state
or agency? For example, what
factors are contributing to the delay of projects and programs?
Highway projects are increasingly being evaluated from multiple perspectives.
While providing additional highway capacity to handle the
growth of travel is still the major driving force that spawns the idea for
a project, other criteria frequently play a significant role in determining
what will be built. Highway
projects are not only being evaluated based upon their potential to move
people but their societal impacts as well.
In examining a project’s impact, emphasis is placed upon notifying the potentially
affected public and soliciting comments on the project.
Additionally, assessments of the project’s impact on the environment
and nearby historical and archeological resources are important determinants
of the final scope of the project.
Maryland’s attempt to manage and limit suburban sprawl has resulted in the
enactment of legislation collectively referred to as Smart Growth.
The central idea behind Smart Growth is that the State and
local governments cooperatively identify boundary areas in which there is
existing sizable development and supporting infrastructure.
These geographies are called Priority Funding Areas.
Development growth is encouraged to stay within these defined
limits by the State’s refusal (with limited exceptions) to fund highway projects
outside of these boundaries.
Lastly, the Maryland State Highway Administration is increasingly viewed
as having not only a role in building and maintaining highways but also managing
the operation of its highway system.
Over time this role has grown in importance as the growth of
State’s population and vehicle miles traveled (VMT) has outpaced that of highway
capacity growth. The agency
has an Advanced Traffic Management System (
ATMS), called CHART, that monitors traffic flows over the major highway
routes and responds to congestion and delay causing incidents and helps restore
the highway system to normal condition.
2.
How are information and new spatial data, tools and technologies helping
you address the issues and factors?
Most of these issues and factors require relevant data to be assembled and
are used to evaluate how a project might potentially impact one or more segments
of society. Prior to having an
on line agency wide GIS these data were in scattered locations and in differing
formats and it was a time consuming effort to aggregate the data.
The agency’s GIS, delivered to over 450 desktops via the network, is now:
·
Reducing the time for:
-
Aggregating Data – From 1 ½ weeks to 2 hours for environmental data
-
Identifying and notifying impacted public – From 8 weeks to 4 hours
-
Analysis of cumulative impacts
·
Improving the quality of analysis
·
Boosting the confidence of key decision makers
The CHART system uses GIS to both provide the traveling public with real
time map displays of highway system conditions as well as in operations management
by mapping the location of key resources (snow plows, emergency response vehicles)
and depicting highway system conditions during weather related events.
3.
Are there one or two specific examples where spatial data, tools and technologies
reduced program delivery timelines, facilitated consensus on project or program
alternatives or enhanced program delivery in other ways?
Having the State’s tax map and assessment database as a GIS spatial layer
has greatly reduced the time to identify affected property owners and create
a database for project mailings.
What used to take about eight weeks for a major project now only takes about
four to six hours.
Having over 25 environmental, cultural, historical, and other spatial data
sets accessible to everyone on an agency server, has greatly reduced the time
necessary to identify the broader impacts of a project.
What used to take about one and one half weeks to assemble
by manual means now can be done in about two hours.
4.
What barriers or constraints have you encountered in gaining support for
spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
In Maryland we have been fortunate that senior management was an early advocate and supporter of developing spatial data tools and services. Senior management envisioned GIS as an important component of the project development process and actively pushed the agency towards creating these tools.
As a result Maryland’s barriers to GIS development were more related to
aspects of building a GIS capability.
Activities which were key to this effort were:
·
Developing a long range GIS strategy – Technology, Organization, Funding
·
Developing a Technology Infrastructure
-
Networking the agency
-
Building the GIS data warehouse
-
Building an easy to use GIS analysis tool
·
Obtaining Funding
·
Fostering a culture of data sharing
5.
What do you believe are the critical pieces that must be in place to ensure
success in this area?
Developing an agency wide spatial data resource is a major effort involving
significant commitment of staff time and money.
Without question having the active support and backing of
senior management is critical to the success of such an endeavor.
With this as a foundation, a long-range plan should be crafted
and consensus reached on what should be built.
The experience in Maryland revealed the following were important
contributors to the successful development of an agency wide GIS.
·
Senior Management Support and resource commitment
·
Inter and Intra agency data sharing
·
Creating a GIS section, a GIS data warehouse, an agency wide GIS analysis
application
·
Training
·
A networked agency
·
A common linear referencing system
8. Pennsylvania Department of Transportation
Frank DeSendi,
Geographic Information Division,
Bureau of Planning and Research,
Pennsylvania Department of Transportation (PENNDOT)
Frank DeSendi, of PENNDOT, reported on the specific application of spatial
analysis tools in PENNDOT.
1.
What are some of the key issues affecting program delivery in
you state or agency? For example,
what factors are contributing to the delay of projects and programs?
The Pennsylvania Department of Transportation (PENNDOT) has several key
issues affecting program delivery.
One of the most frustrating critical path issues has been environmental
review involving cultural resources.
The Department needs to coordinate with the Pennsylvania Historic
and Museum Commission (PHMC) on cultural features.
Reviews include archaeological and historic sites, their
significance and integrity.
The PHMC is a very small commission, processing is slow.
But the biggest shortcoming has been the nature of the data.
Most of the data is paper only; folders are often in use and
unavailable. Only one fragile
set exists for the state. There
are seven separate sets of maps, but none comprehensive.
Many of the materials are physically deteriorating.
Access is restricted, compounded by normal business hours
availability. Along with limited
workspace and inherent travel time, the entire review process was fraught
with inefficiencies, high costs, errors, and oversights.
2.
How are information and new spatial data, tools and technologies
helping you address the issues and factors?
Spatial data tools have begun liberating the cultural resource data.
Although the database is not fully populated (the archaeology
coverage is completely mapped, historic buildings will be completed by 2004),
the use of spatial tools has essentially put the resources on one map.
Therefore, business practices by PENNDOT environmental managers
have changed dramatically. Maps
are being served up across an Intranet.
By clicking on a site, data items are available.
Some digital data, maintained by the PHMC, was previously
maintained on a large mainframe that required programmer time for reports.
In a GIS supported relational database, simple queries permit
sorting or grouping. The environmental
people are enabled to ask their own questions.
Spatial tools have led to early answers, estimates, and scoping.
Maps can be taken to the field without assistance; better
decisions are being made in minutes.
Business practices at the PHMC have been greatly altered too.
Storing data spatially has forced a rigor on the PHMC in the
area of data collection and management.
Previously, the PHMC looked at the data on a case-by-case basis.
Now they can examine preservation, priorities, and eligibility
from a broader perspective.
The PHMC can now ask: Is it important, how much effort do we want to put
into preservation, is it the last one, how many in this region, and what is
the long-term survivability of the property after reviewing the DOT program
with spatial tools.
3.
Are there one or two specific examples where spatial data, tools
and technologies reduced program delivery timelines, facilitated consensus
on project or program alternatives or enhanced program delivery in other ways?
Since the utilization of spatial tools began, communication with the PHMC
has improved. Both sides are
looking at the same information.
The number of ‘gotchas!’ has greatly declined.
During consultations with the Museum Commission, it was common
for the agency to point out certain files or information was missed.
Consultant fee savings are being realized.
PENNDOT staffs now serve as a ‘middlemen’ for cultural resource
data. Department consultants
are supplied with enough information to begin the environmental reviews without
traveling to the PHMC to secure the data.
4.
What barriers or constraints have you encountered in gaining
support for spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
There have been few barriers or constraints in gaining support for spatial
data, tools, and technologies.
GIS activities at PENNDOT were established and benefits realized when the
cultural resource project began.
PENNDOT environmental staff and top management at the PHMC shared the vision
of a cultural resource GIS tool.
The Department provided the financial and technical resources to plan, develop,
implement, and support the initiative.
The PHMC was a partner in the development of requirements.
However, it was not always easy to keep PENNDOT top management
sold on the project. The first
four plus years were devoted to putting information into the database.
Therefore, no cost savings or gains were demonstrable to PENNDOT
senior management. However, they
possessed the foresight to stay with the project and permitted it to proceed.
The Department has paid for the project with transportation
planning funds. Additionally,
the US Army Corps of Engineers (USCOE) provided funding support.
They encountered the same difficulties as the DOT when building
dams.
5.
What do you believe are the critical pieces that must be in place
to ensure success in this area?
There are a many critical pieces that must be in place to ensure success.
The most important is continued top management support.
A well thought out plan, from requirements to implementation,
must be documented and progress demonstrated.
Other issues, such as software development, training costs,
and business culture must accommodate the changes brought on by spatial tool
utilization. Project management
data must be integrated with the cultural resources data so both can be analyzed
together. The data needs to
be portable. Users need to take
the data into the field, make modifications and upload changes into the central
database. The ultimate success
will be the construction of predictive modeling algorithms.
Additional data items such as ortho-photography, soil, slope,
and drainage must be current and available.
Finally, the end user has to want to use the system.
By developing a web enabled friendly system, training time
is minimal, users will be inclined to take advantage of spatial tools.

What are some of the key issues affecting program delivery in
you state or agency? For example,
what factors are contributing to the delay of projects and programs?
·
Communication with districts, MPOs, local agencies, legislature

3.
Are there one or two specific examples where spatial data, tools
and technologies reduced program delivery timelines, facilitated consensus
on project or program alternatives or enhanced program delivery in other ways?
The integration of the program, inventory and highway crash databases through
GIS enabled immediate mapping of high accident locations (HAL).
This provided a two-year improvement in access to HAL sites,
which enabled a more thorough and complete analysis of safety project selection.
Estimated benefits due to projected decrease in accidents
are approximately $ 1,000,000 annually.

What barriers or constraints have you encountered in gaining
support for spatial data, tools and technologies?

10. Minnesota Department of Transportation
Jonette Kreideweis
, Director of the Office of Transportation
Data and Analysis, Minnesota Department of Transportation
Jonette Kreideweis presented the Minnesota perspectives on the application
of spatial data tools and specifically for the streamlining of the cultural
resource reviews.
INTRODUCTION
The Minnesota Department of Transportation (Mn/DOT) has been actively looking
for opportunities to capitalize on spatial data, tools and technologies for
some time. There are a number
of enterprise information projects underway to build a new location data model
and convert the department’s mainframe Transportation Information System (TIS)
to Oracle and expand its mapping capabilities.
There also are a number of more specific GIS applications under development
that are being designed to enhance aspects of the program delivery process.
Like many states, Minnesota is involved in a major initiative
aimed at streamlining the time it takes to plan, design and construct highway
improvement projects. This presentation
will focus on two examples where GIS related tools are helping improve and
streamline project development activities in the Minnesota Department of Transportation
(Mn/DOT). The first example
highlights an application that our department built in cooperation with FHWA
to streamline the cultural and historical review process in Minnesota.
The second example will show how Mn/DOT Metro Division personnel
are working to develop an electronic Environmental Assessment Worksheet that
includes linkages to spatial data.
Mn/Model: Streamlining Cultural Resource Reviews Using GIS
For many years, our department experienced severe delays in obtaining approvals
and clearance from the Minnesota State Historic Preservation Office.
While some highway improvement projects required simple reviews
of project documentation, others required very time consuming and costly field
reviews and surveys. In addition,
there never seemed to be enough staff in our department, and among partner
agencies and external consultants, to speed up the work and keep up with
a growing construction program.
In response to this situation, Mn/DOT began working on a project called
Mn/Model. It is a statewide
GIS-based archaeological predictive model for Minnesota.
Total costs were about $4.5 million, including geomorphic mapping.
It was developed for our department with funding from FHWA over the course
of five years. Improvements
and the programming for new layers of information are continuing, however
at a much smaller scale.
Mn/Model is a tool that indicates the probability of encountering an archaeological
site anywhere in the State of Minnesota.
Its purpose is to help avoid impacts on archeological sites,
streamline the review process and focus expenditures for historic preservation
in areas that are likely to yield the biggest benefits.
Mn/Model was developed using Arc/Info GRID and S-Plus statistical software.
The grid cell size is 30 meters, which is about the same resolution
as the department’s 1:24,000 scale base map.
The model assumes that the present environment can serve a
surrogate for past environments.
Values of environmental variables were analyzed using stepwise multiple
logistic regression. The results
of the regression model were applied to the existing landscape and classified
into probability classes.
A number of factors were analyzed using GIS methods.
For example, the presence of know archeological sites, land
elevation, soil type, the vertical distance to water and distance to the nearest
stream sites were all calculated to identify areas that have a high probability
for cultural, historic and/or archeological significance.
GIS based maps were developed to show the results of applying the model.
Color gradations from gray (showing those areas with unknown
site potential) to orange, red and brown were used to show those areas where
there is suspected to be a medium or high probability for finding cultural
and historic resources.
The map is used as the primary tool for site avoidance and survey design.
It is useful because it makes explicit the extent of archaeological
knowledge. As the results of
more surveys are mapped, the gray (unknown) areas should shrink.
Working with the State Historic Preservation Office and the Office of the
State Archeologist, Mn/DOT staff jointly developed consensus definitions for
four primary categories of archeological constraints. These categories include:
·
Areas to avoid, which include Indian burial mounds and earthworks.
·
Areas requiring control, which include National Register Sites and sites
considered eligible for the National Register.
In these areas, control involves the recovery of artifacts.
·
Areas with limitations, which include all other known sites and high and
medium site potential areas in landscapes suitable for preservation.
Field surveys will be required before highway construction
can commence in these areas.
·
Areas with no known constraints, which include areas that have already been
surveyed, have no known constraints and low site potential.
Mn/Model is used for project scoping, project review and survey design for
all kinds of projects, including new alignments, minor alignment changes,
road widenings, bridge replacements, and corridor studies.
District personnel involved in scoping studies consult with
Mn/DOT archeologists.
Mn/DOT archeologists interpret the model and make recommendations to project
designers, who in turn incorporate Mn/Model considerations into their designs.
The department uses the results of Mn/Model as the basis for a programmatic
agreement with the State Historic Preservation Office.
Based on Mn/Model results, decisions are made regarding which
individual highway improvement projects will be subject to more extensive
surveys and which will be automatically granted historical and archeological
clearance.
Mn/Model has made cultural resource reviews more efficient.
There is faster turn around for project reviews.
Fewer mitigations are being required and fewer memorandums
of understanding between our department and the State Historic Preservation
Office are being written. As
a result, the project has resulted in significant cost savings. Cultural and
historical surveys are expensive and in Minnesota there are only certain times
during the year when they can be done.
If cultural and historic sites can be predicted and avoided early
in project planning it can greatly minimize field survey needs.
The response to Mn/Model has been overwhelmingly positive.
It has demonstrated that archaeological predictive models
can make an important contribution to cultural resource management.
In summary, significant time and cost savings are resulting
from:
·
Better data and tools for cultural resource reviews.
·
Reductions in archeological survey costs by more focused design.
·
Design of projects that from the beginning seek to avoid impacts on archeological
sites.
Additional information on the Mn/Model project may be found at the web site:
http://www.mnmodel/dot.state.mn.us
.
Mn/DOT Metro Division’s Electronic Environmental Assessment Worksheet
Mn/DOT Metro Division staff is taking the Mn/Model concept and applying
it in a more generalized manner to prepare electronic environmental assessment
worksheets for highway improvement projects.
These electronic environmental assessment worksheets are hyper-linked
to a variety of layers of environmental data that are being integrated and
mapped using GIS tools and applications.
This effort began in response to several issues.
First, Mn/DOT Metro Division project designers and planners
were encountering project delays due to what came down to not having the “right
data” at the “right time”. In
addition, traditional project documents were time-consuming to prepare, costly,
relied on a variety of inconsistent data sources, and were hard to copy and
share. Project decisions were
being held up because partner environmental agencies simply didn’t trust or
understand where Mn/DOT staff was coming from.
The solution has been the development of electronic, on-line environmental
assessment worksheet document.
These documents are:
·
Prepared in Word
·
Available on the WEB, including features to share agency comments on-line.
·
Hyper-linked to GIS products.
The GIS products are based on data sources identified early in the process
and mutually agreed upon by the environmental agencies that will be reviewing
the document later. Data elements
include:
·
Street series maps, aerial photo and USGS topographic maps.
·
Soil surveys
·
Generalized current land use
·
Future land use
·
Water resources, floodplains and wetlands
·
Elevation and soil types
·
Bridges, culverts, streams and water erosion
·
Hazardous waste and identified contaminated properties
·
Accident data
·
Traffic volumes
·
Nearby resources, trails and recreation areas
·
Identified contaminated properties.
Mn/DOT Metro Division staff has used the new tools for several projects
and there seems to be great promise for streamlining environmental review.
CONCLUSION
These two examples show how GIS data, tools and technologies are helping
to streamline program delivery activities in Minnesota.
They are successful for four primary reasons:
·
They are specifically designed to address current problems and they are
producing measurable results.
·
They focus on standardizing, sharing and making key data available early
in the highway design process.
·
They use maps and spatial data to highlight specific areas where impacts
should be avoided or minimized.
·
They were developed in partnership with internal and external agency partners
involved in process reviews and approvals.

GIS Program Manager, Virginia Department of Transportation
Dan Widner presented a summary of spatial analysis activities in the Virginia
Department of Transportation.
1.
What are some of the key issues affecting program delivery in your state
or agency? For example, what
factors are contributing to the delay of projects and programs?
Accessibility to information:
Much information remains today in “stovepipes” of data repositories that
are limited in their accessibility across the enterprise.
This is caused in part by the lack of implemented data standards
and also by the lack of truly integrated information systems, both spatial
and non-spatial.
Reliability of information:
Since not all data is accessible across the enterprise and not necessarily
standardized, questions arise about the reliability of available information.
Disparate and duplicate means of tracking data:
This follows the “reliability of information” above in that at the local
level personnel utilize the best tools available.
This may not be consistent across the enterprise due to a
variety of skill sets, abilities, and comfort with certain technologies.
As information “funnels downward” to a single statewide source,
processing time and data quality become issues that must be addressed, taking
valuable time in the process.
Spatially enabling data throughout the enterprise:
In a large organization such as the DOT, where data is distributed
throughout the organization in many locations and formats, it can be difficult
to consistently standardize location information so it can meet the demands
of greater accuracy and precision that new spatial technologies are capable
of offering.
2.
How are information and new spatial data, tools and technologies helping
you address the issues and factors?
Standardization of location information, facilitation of access to information,
and consistent technologies:
By standardizing location information across the enterprise, access to
information is improved. This
makes it easier to integrate a variety of data sources.
Once data is integrated more uniformly, newer web-based
technologies can provide a consistent approach across the board.
3.
Are there one or two specific examples where spatial data, tools and technologies
reduced program delivery timelines, facilitated consensus on project or program
alternatives or enhanced program delivery in other ways?
Web application for priority construction projects:
VDOT is currently going through a re-prioritization of its construction
program due to budget reductions.
Spatial data, tools and technologies have been utilized to facilitate the
decision-making process by providing ease of access to information and comparative
capabilities in an intuitive and familiar map interface.
Web enabling of environmental review process:
This is a top priority for VDOT’s environmental and data management organizations.
A “rule of thumb” applied at VDOT states that for each month
of delay to each $50 million worth of construction projects, $166,000 is added
to the cost of the project.
VDOT is working with natural resource agencies in the state to improve the
ease of access to data and information using spatial data, tools and technologies.
4.
What barriers or constraints have you encountered in gaining support for
spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
Education in the value and utility of such technologies:
Quite often personnel who have never before had exposure to spatial data,
tools and technologies do not know the value that can be provided to their
everyday business functions.
Education and exposure is the key to overcoming this deficiency.
Buy-in at the highest levels of the department:
It is absolutely crucial that management at the highest level understand
and agree with the need to implement spatial data, tools and technologies.
This then has a ripple effect upon any budget requests and
staffing needs for such implementations.
Demonstration of tangible results help in securing resources:
In the quest to secure buy-in for spatial data, tools and technologies,
a quick and effective demonstration of the power of such technologies helps
tremendously in securing the necessary resources.
Some rules of thumb are: (1) simple yet powerful applications,
(2) choose obvious areas of need, (3) ease of access and understandability,
and (4) don’t oversell your capabilities.
Understanding of the time and effort required to build spatially enabled
systems: Many potential
end users lack an awareness of the level of effort involved with the development
of spatially enabled information systems.
This can create barriers and cause a lack of confidence in
the tools and technologies.
5.
What do you believe are the critical pieces that must be in place to ensure
success in this area?
Suitable communications network with adequate bandwidth:
As more and more spatial data becomes available, the necessary infrastructure
must be in place to support large quantities of data.
Raster data in particular requires a large bandwidth.
Virginia is in the process of developing a high-resolution
statewide digital orthophoto base.
How do you share such mass quantities of imagery to those who
can most benefit from it?
User accessibility to the most accurate and timely information available:
Ease of access to spatial data, tools and technologies increases the accessibility
to data that is both more accurate and timelier.
The obvious advantages posed by the Internet point to this
fact. A good example is the Geography
Network of ESRI. Using the
Internet one can access spatial data without copying and without the necessary
overhead of data maintenance.
Spatial data technologies and the marketplace must be in step:
There is a crisis in expectation due in part to the marketing
promises that have been given by software vendors and service providers.
Often advertised toolsets are not as robust as advertised,
or are unstable, which leads to software problems becoming a limiting factor
in the implementation of truly integrated spatial data.
12. Michigan Department of
Transportation
Ron Vibbert,
Manager of Strategic System Operations and Maintenance Section, Michigan
Department of Transportation
Major program delivery issues in the Michigan Department of Transportation
(MDOT) can be characterized in two ways. First, is the ability to have design
plans ready in time for contract lettings. This is a problem, as MDOT decided
several years ago to “front load” our lettings such that we would have plans
available for lettings in the October-November time frame for the following
construction season, instead of spreading the lettings over several months.
Having larger lettings has enabled our contractors to have a better idea of
the volume of work we will be requiring for the next year and thus better
plan for their resources. As a result, we have found somewhat better project
pricing as well. The challenge however is to have the plans ready. This causes
“peaky” workloads. To some degree we have compensated for this by planning
our programs 5 years in advance, so we can get started on our project development
process in advance, and can then take advantage of the long lead times to
do the required design, right of way, and clearance work.
The second challenge is long term. Are we delivering the long-term performance
goals we have committed to? Are our actions contributing to achieving the
goals we’ve said we’ve wanted to provide to the public? And are we executing
efficiently over time? Or are we visiting the same locations over and over?
We have been using spatial technologies in various ways to help resolve
some of the longer term issues, as the shorter term ones are pretty much
contained in our design process. They do use GPS for survey work, but that
is farther along the process than where we’ve been using spatial technologies
in the more programmatic decision making processes.
Much of what can be said here sounds very much like the usual ads for GIS
technologies. We have found that our data is analyzed differently when it
is reduced to map form. Most of what we do has a spatial component, and like
a picture, a good GIS based map is worth volumes of text and numbers, making
conclusions explainable to policy makers.
Additionally, our data quality has improved too. When people see their data
on a map, we’ve found that they usually comment that “your GIS program is
wrong”. We then have to show them that it is their data that is goofy and
then they go to clean it up. We have also gained further support
for GIS/GPS activities by helping folks clean up the data, and then showing
them how to use GIS technology to keep it clean.
Some of the more common areas where we’ve used GIS/GPS technologies are:
·
Environmental Clearance – Our environmental clearance staff goes directly
to our Natural Resources site to get maps of environmental features and environmentally
sensitive areas. This speeds many of our clearance processes, while since
we can reference our Natural Resources site in our analyses, our credibility
goes up as well, while the whole map requesting process has been eliminated,
at least with our DNR.
·
GPS Surveys – We established 12 high accuracy GPS stations for survey preparation.
These are used to speed the survey process, and help support the accelerated
design schedules. We make these stations available to non-MDOT contractors,
and other state agencies.
·
High Impact Project Presentations
Every year our Regional offices make presentations to executive
management about those projects to be constructed in the next year that will
have high transportation impacts on the public. These include those that will
constrain traffic and thus cause unexpected congestion, and those that will
otherwise affect considerable traffic during construction efforts. These are
made with GIS support, as that allows presentation of the activities spatially.
·
Call for Projects
Projects are proposed for construction 5 years out. These projects
are identified using a set of system-wide transportation goals, with each
Region having a strategy identified for them to use to meet the identified
statewide goal. This requires system condition forecasts to be made.
Displaying the existing and future
condition states, given the strategy and propose projects, are accomplished
using GIS technology. Further, these maps are generated using data that project/systems
managers enter into our project planning database, causing a high degree of
confidence that the data being displayed is “live”, and increasing the level
of “ownership” of the data for each system manager. The impact on our GIS
staff is that they must ensure the data is available in a form usable by
GIS software, by regular, non-GIS users.
·
Asset Management Data Collection -- MDOT, in conjunction with our county
and city political organizations, LTAP, and several MPO’s conducted a pilot
pavement condition collection project in several counties. This effort used:
–
Off the shelf GIS software
(Caliper’s Maptitude product ~ $400/vehicle);
–
Off the shelf GPS equipment
(Garman, roughly $250/vehicle);
–
A standard portable;
–
Our standard statewide
Framework products;
This effort collected pavement condition
and rudimentary roadway attributes (such as number of lanes, pavement type,
pavement condition). Since this information was collected using a GPS the
information was immediately displayable, and could be then incorporated into
our linear referencing system for subsequent use by other data collection
activities.
This pilot supports proposed legislation to collect pavement condition information
annually on our Federal Aid system, and to perform condition analyses and
begin to direct expenditures through a Transportation Asset Management Council,
also created by the legislation.
Much of our progress in implementing spatial technologies in the past has
been the result of
·
Not having standards
, mainly an underlying GIS base map. The recent delivery of the state’s
Geographic Framework project has caused a flurry of activity, and we are
overcoming this barrier because we now have a base to focus on;
·
Uncertainty about which GIS tools to implement
– Each tool has their own set of advantages, and disadvantages. We have
found that empowering users with a GIS tool they can use, and some minimal
standards, user training, and subsequent support goes a long way to building
a GIS community. We’ve discovered we cannot have a cadre of GIS ‘priests’,
and still expect to succeed;
·
Storage and distribution
, and maintenance is always an issue. And continues to be.
We are looking to implement Oracle spatial;
·
Lack of GIS savvy IT staff, and GIS savvy IT staff
. Our GIS staff is primarily user-based, being expert in the use of the
software to produce GIS based results, but not very familiar with data storage
principles or methods. Conversely, our IT staff is not GIS/GPS oriented.
This is a stretch for them as this isn’t data processing, and it’s not report
generation. This is a current hurdle we need to overcome.
We have been successful in garnering, and continuing the support for GIS/GPS
activities. This has resulted in a series of Geographic standards and usable
products, and a geographically referenced linear referencing system. We have
spent the money to locate all of our projects of the last 10 years or so,
and to provide a stable future base for referencing our roadway attributes,
as well as projects.
Other aspects of getting and keeping support for GIS/GPS activities are
that we have been able to show payoffs of using GIS in current decision-making/other
business processes. We have focused on providing solutions, not technology,
and we have been able to deliver on almost all of these.
Lastly, we have focused on enabling our users to use the technology, and
have made considerable efforts to extend GIS training to every region and
local office. We then support them with updates, basic data, and telephone
support to make sure the capabilities we provide are current and useful, and
that they can use them. We have found that our users are advocates for future
spatial activities.

Administrator, Office of Technical Services, Ohio Department of Transportation
Jim McQuirt presented an overview of spatial analysis applications in the
Ohio Department of Transportation.
1.
What are some of the key issues affecting program delivery in
your state or agency? For example,
what factors are contributing to the delay of projects and programs?
Environmental hot spots (e.g. archeological and historical sites, wetlands,
cultural resources, contaminated sites, etc.) and Right of Way (ROW) issues
can create delays in the delivery of projects and programs.
Funding also has a major influence on what and when projects
and programs are delivered, including the large dollar amounts that are expended
on Preliminary Engineering (PE) and ROW and change orders for projects.
Identification of environmental hot spots historically has been accomplished
through a manual search of paper documents or labor intensive seek and find
surveys. The paper documents
reside primarily in two separate locations at the State Historic Preservation
Office (SHPO) and the Department of Natural Resources (ODNR); they are one
of a kind and in many cases are in poor condition.
The inefficiency of compiling usable information from the
paper documents results in higher program and project costs due to increased
delivery times and errors and oversights requiring revisiting environmental
issues.
Revisiting ROW acquisition can delay programs and projects.
Often the need to revisit is a result of changes in design
due to missed items such as utilities, sewage systems or environmental discoveries
in the planning and National Environmental Protection Act (NEPA) stages.
Lack of adequate data to effectively evaluate the impact of
a project can increase costs due to delay and acquisition costs.
Large dollar amounts are expended annually in PE and ROW activities ($40
million) and change orders ($50 million) in delivering Ohio’s $1.2 billion
construction program. Any savings
in these areas could be used to increase the annual construction program.
In addition, maximum utilization of available funds for program
and project delivery can be drastically influenced by the types of decisions
that are made in program and project development.
2.
How are information and new spatial data, tools and technologies
helping you address the issues and factors?
Several efforts are complete or are underway to convert paper documents
into formats compatible for use in GIS.
ODOT has jointly funded these efforts with SHPO and ODNR:
In the past, archeological sites were located and written on paper quad
sheets. The records were located
at SHPO and were indexed with card filing system.
ODOT would have to locate sites of interest by using the quad
sheets and the index cards.
The needed quad sheets and associated typed inventory reports were scanned
and copied and the copies were returned to ODOT for incorporation into the
planning and environmental process.
To improve this cumbersome procedure, a two-phase effort was
undertaken to convert paper documents to a digital format compatible for GIS
use. The first phase was to
create a digital file of archeological sites and associated attributes, and
is now complete. The second phase
of quality assurance/quality control (QA/QC) is now underway, to resolve inaccuracy
issues between maps and attribute databases; it is scheduled to be complete
in 2003. QA/QC is complete for
22 of Ohio’s 88 counties and is being used by environmental staff.
It has significantly reduced time and costs for preparing site
maps.
Historical sites are handled similarly to the archeological sites mentioned
above, and a current effort is underway with SHPO to create a format for GIS
use. This effort will be complete
in 2003. It will also reduce
time and costs for preparing site maps.
A wetlands inventory was created from paper maps residing at ODNR.
The wetlands were originally identified by ODNR using Landsat
photos from the mid 1980's.
Even though the ODNR interpretation of wetlands differs somewhat from both
Ohio and US EPA’s, the digital data has provided a very good planning tool
and starting point for environmental work.
As actual field surveys are completed for projects, the boundaries
of wetlands are updated from location information obtained from mobile GPS
backpacks.
Similar efforts are underway in the location of, and creation of, digital
formats for underground mines (2004), bedrock topology and geology (2002),
soil types (2006) and hydrography (Pilot complete).
As these are completed, it is anticipated that they will help
to lower program and project costs.
New technology is also being investigated by ODOT as a means to improve
program and project delivery.
A research project is near completion, which looks at using low altitude
airborne multi spectral scanning for preliminary analysis of highway project
sites. It is anticipated that
better and more cost effective results can be obtained in identifying environmental
sensitive areas such as streams and springs, ponds and wetlands, field tiles,
potential hazardous sites and archeological sites.
Light Detection and Ranging
(LIDAR) technology is also being investigated to lower project costs for
detailed mapping and design.
GIS tools are being used to analyze data from numerous other in-house data
files such as pavement and bridge condition, congestion, accident and highway
sufficiency to help develop multi-year district and county work plans.
3.
Are there one or two specific examples where spatial data, tools
and technologies reduced program delivery time lines, facilitated consensus
on project or program alternatives or enhanced program delivery in other ways?
Example 1:
The ODOT director recently testified before the Ohio Senate’s Highways and
Transportation Committee. His
testimony was in preparation for the next biennium budget.
The presentation consisted of our bridge and pavement analysis
process; it impressed the committee and assured them that the state transportation
system is in good hands. The
analysis, which so impressed them, would not have been possible without the
use of GIS and the Department’s Base Transportation Referencing System (BTRS)
efforts to establish an enterprise data warehouse.
That analysis enabled ODOT to more clearly predict our system
trends and conditions. The presentation
came at a time when legislatures in some states were attacking their DOT's
for inefficiency, Ohio instead being held up as an example to all Ohio cities
and counties seeking improve their infrastructure management.
Example 2:
GIS was used to integrate a variety of spatial data (soil, wetlands, land
use, land cover and aerial photography with highway network) from different
sources to help expedite a proposed project (GAL - Bob Evans Ave. on State
Route 7) in the city of Gallipolis.
The information was used as the basis for a Purpose and Need
Statement for a proposed new transportation facility designed to alleviate
congestion on State Route 7.
The information was also used at several public meetings to gain support
for the project, which had local opposition.
4.
What barriers
or constraints have you encountered in gaining support for spatial data, tools
and technologies? How have you
been able to secure the resources for these new data, tools and technologies?
Perhaps the largest constraint in implementing GIS in the past was the lack
of a sound enterprise level data warehouse.
One of the major barriers originally encountered was
the proprietary view of owners of the various system and/or datasets available
throughout the department.
Many of the issues and concerns were alleviated through the creation of
a committee consisting of owners of all the major systems. It was called
the Base Transportation Referencing System (BTRS) Committee and was charged
with developing recommendations regarding standards and polices for the development
of an enterprise data warehouse that would facilitate integration with GIS.
Implementation of GIS in each of ODOT’s twelve (12) districts has been a
challenge. In addition to decentralization
and other organizational changes, the Department has reduced staff by nearly
1400 employees, statewide. As
a result of reduced staffing levels, and increased district responsibility
for program and project deliveries, dedicated staff for GIS related activities
are not always available.
ODOT has standardized on SYBASE for its enterprise database; this has created
additional challenges in implementing a GIS, since the major GIS vendors don’t
support SYBASE to the level of other database vendors, such as Oracle, DB2
and Microsoft.
5.
What do you
believe are the critical pieces that must be in place to ensure success
in this area?
Top-level management support is crucial to ensuring success, as is a clear
well-defined action plan. The
action plan must be developed with input and consensus from all potential
GIS users. An accurate, integrated,
seamless and easily accessible enterprise data warehouse with local maintenance
is an absolute requirement for long success.
Finally good software, application development, training and
communication are needed to ensure current and future success of GIS.
14. Using Spatial Data, Tools,
and Technologies

Mississippi State University,
representing the National Consortium on Remote Sensing in Transportation
– Environment (NCRST-E), one of four consortia funded by Research and Special
Programs Administration’s program on remote sensing for transportation.
Key Issues
·
Funding in transportation agencies is shrinking which places increased pressure
on project delivery.
·
Agencies are directed to streamline planning and assessment processes as
well as other components of project delivery.
·
Environmental assessment and other project planning and assessment processes
can be streamlined using appropriate data.
·
Geospatial data of appropriate scale used early in projects can significantly
assist in planning, assessing constraints, and screening and presenting alternatives.
·
Funds for enterprise data development, management, and analysis application
development are very limited.
·
Developing appropriate data and enterprise resources requires considerable
investment and commitment by agency leadership. The competition for resources
within agencies can be significant and there is risk involved in investing
in enterprise GIS IT.
Data Development and Management Issues
Agencies must determine requirements for specific geospatial data types
for different applications (increasing resolution and/or collection rate/frequency):
·
Basemap
Data (NCRST-E focus)
·
Planning
Data (NCRST-E focus)
·
Assessment
Data (NCRST-E focus)
·
Design Data
·
Engineering
Data
·
Operations
Data
Data Issues
·
Digital data libraries of geospatial data layers must be distinguished from
the collection of operational time series or real time information collected
at locations.
·
Geospatial data layers must be maintained, basemap and image data refreshed,
and operational data collected at appropriate intervals to facilitate change
assessment and decision making.
·
To conduct GIS analysis of operation data, geospatial data must be available,
attributed, and relationally linked to operational data. Therefore, geospatial
base map data layers are a prerequisite to assessing operational data in
geospatial context.
·
Look at data needs from a fresh perspective and assess the accuracies and
tolerance that can actually be used in the construction process.
Many of the practices taken as standards were developed decades
ago and may not still be appropriate today.
Since very high accuracy measurements are expensive, “overmeasurement”
can be very costly so reexamination of measurement standards could have significant
payoffs.
Helpful Technologies

products in ways that are surrogate for, improve on, or substitute for, existing
processes:

MSU was asked to develop research to accomplish the following
tasks:
·
Evaluate
new hyperspectral image, elevation, and hydrologic data;
·
Develop
enhancements for wetland identification methods; and

Evaluate
the differences between traditional wetland mapping techniques for assessment.
4.
What barriers or constraints have you encountered in gaining support for
spatial data, tools and technologies?
How have you been able to secure the resources for these new
data, tools and technologies?
Improved software and processing algorithms are needed to extract specific
information products from geospatial image data.
Computational resources requirements for new data types, dense data, and
large areas of coverage are poorly understood and underestimated.
Existing commercial solutions do not adequately deal with data complexities
of new data types or quantity of data for large areas of coverage (web mapping,
LIDAR mass points, HIS, etc.)
5.
What do you believe are the critical pieces that must be in place to ensure
success in this area?
·
Success stories must be appropriately validated, benchmarked, and presented
to decision makers.
·
Strategic partnerships and funding approaches are required to develop appropriate
data resources (Virginia is using Wireless E911 funds for aerial photography).
·
·
Computational middleware for doing the “heavy lifting” of data processing
and analysis to extract needed information.
·
·
Data serving, storage, and archival will require significant information
technology development, investment, and planning for future needs.
·
·
Technical outreach must match research support and information technology
resources with agency projects that seek to deploy new geospatial technologies.
·
·
Technology reviews and case studies should be developed to improve technology
transfer.
·
·
Economics of geospatial data development and technology implementation must
be better documented so that decision makers may balance cost with benefit
in technology deployment.

Proposed Research: Institutional Evolution of GIS Discussion
There is a need for a "cookbook" package that could contain examples of
best practices and benefits of GIS in terms of improving transportation
development and delivery in transportation agencies. This "body of evidence"
could be used by others to present and sell the benefits of GIS and other
spatial tools. This could be accomplished by the committee or through an
NCHRP Synthesis project
Another Peer Exchange to follow up on the benefits discussion was discussed.
The follow up peer exchange could be held approximately 6 months from this
peer. Another discussion item
could be the above-described "cookbook". Examples of benefits may include
actual quantifiable benefits or be expressed in terms of added value to the
agency.
There was discussion of the need for an NCHRP project to investigate how
business process reengineering must take place in State DOTs in order to better
manage data for decision making using the constantly emerging spatial technology
tools. Some of the items brought
up by Ysela Llort should be investigated though this mechanism
(e.g.
inclusion of freight and multimodal considerations, institutional arrangements
necessary for success, federal partner involvement, integration of performance
measures, data accuracy, and data analysis.)
An idea for another Peer was also discussed: the role of Roadway Information
Systems; why state DOTs collect what they do and why.
It was agreed that this committee is not the only body that has a stake
in the topic of GIS and turning data into information for decision making.
Others include AASHTO, GIS communities, federal agencies,
and others.
17. Compilation of Benefits from Spatial Analysis Technologies
At the conclusion of the meeting, the Peer Exchange participants were instructed
to develop a list of benefits accruing from the applications of spatial analysis
technologies to agency operations.
These benefits were identified by Peer Exchange participants and
are not a comprehensive listing of benefits within their agencies.
Benefit categories and the identified benefits follow: Benefit
Categories
Environmental Analysis Accident Mapping
And Analysis Roadway Inventory

Communications And Customer Service Cartography/Mapping Organizational
Communication Internet Road
Conditions Maintenance And
Operations Right-Of-Way/Land

Management Permits Aeronautics
Environmental Analysis
The Texas Department of Transportation’s (TxDOT) Environmental Division
also uses GIS applications for environmental assessment work related to the
following types of projects: Noise barriers, Wetlands, Navigable Waters,
Indian Homelands, Historic Registered Sites, Archeology, Black Capped Vireo
Habitat Areas, FEMA Flood plains, Impaired Water bodies, Class IV wells,
Air Quality. ( Texas)
GIS is currently being used to analyze land use, traffic flows, cultural
and natural resources impacts and to improve environmental documentation.
District planners and pre-design engineers are able to produce
maps that show construction projects by year and those that are part of
20 year plans. GIS has increased
the quality of the maps and reduced the amount of time to keep them updated.
GIS has also provided enhanced access to large amounts and many different
layers of data that were not easily available in the past.
Additionally, it has improved District personnel's ability
to try more "what if's" and improved their ability to create exhibits to aid
in program and project discussions.
Having statewide aerial, quad, county, and city maps online has
reduced the cost and time of stocking lots of paper maps. (
Minnesota)
Minnesota Department of Transportation (MnDOT) has developed a GIS application
called Mn/Model for archeological predictive modeling, natural resource mapping,
and wetland inventory/monitoring. Mn/Model is helping Minnesota Department
of Transportation identify natural and cultural resource impacts at an early
stage to better analyze alternatives or include mitigation efforts early in
the project delivery. It is
estimated that Mn/Model is resulting in savings of approximately $50,000 for
each highway project and $25,000 for each bridge project included in the
construction program that require Phase I cultural resource surveys.
In addition, Mn/Model has permitted the department to accommodate
an expanding construction program without adding additional cultural resource
personnel. In other Environmental Services activities, GIS applications are
reducing the need for field reviews by allowing specialty staff to make preliminary
evaluations using the data on servers. GIS has allowed them to prepare better
exhibits to help designers and regulatory agencies. Overall they say their
evaluations are quicker and of a higher level of detail than before. (
Minnesota)
Environmental & Related Reviews - Having over 25 environmental, cultural,
historical, and other spatial data sets accessible to everyone on an agency
server, has greatly reduced the time necessary to identify the broader impacts
of a project. What used to take
about 1 ½ weeks to assemble by manual means now can be done in about
2 hours. (
Maryland)
Mapping SMART GROWTH areas and other issues, including sidewalks, is done
with GIS, would almost be impossible without it. All archeology and historical
site information as well as Threatened & Endangered species information
is available in the GIS DataViewer, analysis would be very difficult without
it. Census and Environmental
Justice information is available in the GIS DataViewer, analysis would be
very difficult without it. Enterprise
and Empowerment zones information is available in the GIS DataViewer; analysis
would be very difficult without it.
Project Planning uses all these layers to analyze the potential
positive, as well as negative, effects of a road project.
(Maryland)
GIS provides for the integration of environmental information of use in the preliminary design phase of a roadway or structure project. This environmental information included wetlands, endangered species, archaeological sites, park districts, historical sites and water resource information. This information assists in obtaining appropriate signoffs from agencies by identifying projects within the geographic limits of sensitive areas. Efficiency Benefits result from the rapid identification of the sources of environmental impacts for action in the preliminary engineering process ($200,000 estimated annual benefits). (Illinois)
Impacts on the I-69 project: (I-69/Delta Framework GIS Effort) (
USEPA)
·
Provided consistent baseline environmental data to DOT’s, contractors and
NEPA reviewers, saving time and money to have these efforts duplicated by
each staff member.
·
Shortened primary review time of Scoping materials, DEIS, proposed alignments
and other NEPA documents by NEPA reviewers by having relevant environmental
data available and on-hand.
·
Identification of ecological and programmatic priorities for natural resource
agencies in the Mississippi Delta is leading to the development of proposals
for the creation of large-scale enhancement projects, such as habitat and
carbon banks, wetland restoration, etc, via TEA-21 funding.
These projects (still in the pipeline) will be of exponentially
greater environmental value than traditional highway mitigation efforts, as
well as streamline future highway mitigation procedures with a series of
established (and functional) banks and reserves.
Accident Mapping And Analysis
Currently using GIS to map accidents, identify locations with higher concentrations,
and target safety improvement investments. This is resulting in better analysis
and communication of potential project needs.
They are also using GIS to do data quality checks (i.e.: an
accident may be coded on a section of road, but coded to a wrong county).
(Minnesota)
Accident Analysis is speeded up using GIS. (
Maryland)
Illinois DOT’s Accident Mapping and Analysis GIS project provides the ability to display and analyze accidents on the highway network. This project is of major use to the Department in program development and in roadway operations. GIS enables not only the display of high accident locations, but also the detailed evaluation of individual accidents at these locations. Examples of accident analysis GIS displays include roadway deficiencies, intersection analysis, collision diagrams, high accident location identification and rail crossing accidents. The accident cluster sites are also analyzed with information from the roadway inventory files such as friction characteristics, lane width and truck traffic. Other relevant information includes historical trends, fatal and personal injury accidents and wet weather accidents. Efficiency Benefits directly result from the automated and rapid preparation of High Accident Location (HAL) maps that were previously manually prepared (with a two year delay in usage). Efficiency Benefits also result at the district level from the access to complete accident inventory and history. Effectiveness Benefits (better decision making) result from the accessibility and use of more current accident information and the selection of the most appropriate high accident sites and remediation strategies for program development and roadway operations activities ($290,000 estimated annual Efficiency Benefits, $1,050,000 estimated annual Effectiveness Benefits). (Illinois)
Roadway Inventory Data Management
Improves Data Accuracy – Viewing maps as opposed to tabular reports makes
the identification of data entry errors easy.
Staff can look at a map and say, ‘we didn’t do that there,
we did that here’. Improved data
accuracy means better decisions are being made.
Additionally, data QA/QC can be done in a highly productive
manner. (Pennsylvania)
The Illinois Department of Transportation (IDOT) uses GIS to access, display
and plot roadway, structure and rail crossing inventory information to verify
data for the Department’s transportation infrastructure.
Efficiency Benefits accrue from reduction in effort in accessing
inventory information. GIS
also enables the mapping of commonly queried data elements such as functional
classification, roadway jurisdiction and maintenance responsibility. Districts
experience personnel savings through access and management of inventory information
in a cartographic form. GIS enables more efficient maintenance of the spatial
link/node base resulting in direct personnel savings.
IDOT uses GIS to submit the Linear Referencing System base
map to FHWA ($210,000 estimated annual benefits). (
Illinois)
State and
federal legislative district boundaries and urbanized area limits change
with every new census. The work
to prepare new maps displaying these boundaries was very time and labor
intensive. These legislative
and urbanized area boundary revisions resulted in a large number of changes
to the road inventory data elements, which were very time consuming for district
and central office personnel to incorporate. GIS provides the capability
to prepare work maps to develop new urbanized area boundaries. In addition,
the digital incorporation enabled the automatic conversion of data in road
inventory for functional classification, legislative district and urbanized
area changes. This results
in significant central office and district personnel savings ($110,000 benefits).
(Illinois )
GIS helps verify the validity of generated Average Daily Traffic (ADT) data
with the raw traffic counts supplied by the district.
The project also provides a direct GIS interface between the
personal computer traffic count database and road inventory files.
Benefits at the district level would result from the automated
production of traffic work maps to check the reasonableness of raw traffic
counts. GIS also enables the
electronic preparation of traffic count maps for submittal to the central
office for county and state highway traffic map verification and preparation
($120,000 estimated annual benefits). (
Illinois)
Pavement Asset Management
"Zap-A-Map" currently is used by pavement engineers to produce district
maps displaying various pavement data for analysis.
(Texas)
Currently using GIS as part of the pavement management system to map, analyze,
and forecast pavement conditions and estimate needed treatment types and dates.
GIS is helping them prepare better exhibits faster to display
the results and recommended treatments. (
Minnesota)
Currently using GIS to analyze and create maps for various traffic and roadway
datasets. For example, one application
maps data on 20-year cumulative estimated Equivalent Single Axle Loads (ESALs)
and heavy commercial truck traffic to assist District Materials and Maintenance
Engineers in determining what materials to use for spot overlays and pothole
repairs. This Office maintains the department's roadway inventory, construction
history logs and a number of other core transportation data (accidents, pavement,
sufficiency, bridge, rail grade crossing, traffic counts).
GIS is helping them see data errors, provide analysis and
mapping products for customers that was not as feasible in the past. GIS
also holds promise in helping this area move more responsibilities for data
maintenance closer to local government data sources, resulting in more timely
and higher quality data. (Minnesota
)
Pavement division puts together a report on the annual pavement activities
with some maps describing where they were working and why. (
Maryland)
Illinois DOT uses GIS displays showing critical pavement performance and
inventory characteristics to assist the planning and programming process.
This includes assessment of pavement conditions such as the
Condition Rating Survey (CRS) values, distress, roughness and rut depth.
Other analysis elements included historical condition values,
latest improvement type and location of backlog for pavement condition trigger
values. Efficiency Benefits result from the automated annual production of
the CRS map using inventory data by district offices ($220,000 estimated annual
benefits). (Illinois)
Structure Asset Management
Currently using GIS to map annual overweight truck traffic permit holders
with the locations and restrictions on Minnesota Department of Transportation
bridges statewide. Users are able to instantaneously retrieve bridge hydraulic
information on bridges over water using a custom built GIS application.
Bridge Hydraulic personnel are able to view real-time waterway
information to determine river flow and flood stage using a GIS application
that ties to the USGS real time gauge station network.
This is used extensively during flood events with daily flood
stage maps being created for the State Bridge Engineer. Scour critical bridges
are mapped and the flood plans are supplemented with a GIS application.
District hydraulic personnel are able to create, store, maintain
and analyze data on non-bridge hydraulic features under Minnesota Department
of Transportation's roads. Hydraulic Engineers use specific sets of GIS data
to aid in the development of hydraulic models for bridge and non-bridge hydraulic
features. All of these examples involve time/resource reductions due to the
efficient and fast availability of necessary data to an individual's workstation.
(Minnesota)
The Illinois Department of Transportation uses GIS to display and analyze
critical bridge and structure characteristics.
GIS outputs include the identification of load ratings, structural
deficiencies, inspection status, condition history and the location of backlog
structures. Also important
is the analysis of functionally obsolete and structurally deficient structures.
Efficiency Benefits result from the automated visual identification
of structures meeting certain structural analysis criteria such as load rating,
functional obsolescence and structural deficiency. This project would also
provide external benefits to local agencies ($87,000 estimated annual benefits).
(Illinois)
Public/Legislative Communications
and Customer Service
The bridge locations from the department Bridge Inspection and Appraisal
System (BRINSAP) database were ported into GIS.
The bridges with load restrictions were identified and displayed
as a point on the GIS centerline network.
These locations were then published on the web as a
Load Restricted Bridge application.
The application provides a way to communicate to the public the
locations of hazardous structures.
The use of the BRINSAP application system and the GIS network
provided a much cheaper and faster way to communicate this information than
would have been accomplished through field inventory.
The project was completed in 3 months instead of the 18-24
months that would have been needed to inventory all bridges in the state.
(Texas)
Project Planning Maps provide a great communication tool for community meetings.
They produce these in GIS.
Design Files with Imagery provide a great communication
tool; people can see what areas will be impacted.
Using design files with imagery helps people make good decisions
about where and how plans may impact the current conditions of the area.
(Maryland)
Spatial data technologies are especially effective at legislative, public,
and media meetings. In particular,
hard copy maps help convey decisions to all levels of understanding.
For example, legislators regularly compliment the spatial
capabilities of the Department during legislative contact meetings.
They quickly grasp the roadway program in their district and
frequently request maps to hang in the office.
During a public meeting, a district engineer’s decision regarding
safety improvements at a certain intersection was challenged.
Attendees believed a more pressing need existed elsewhere.
The district engineer produced a crash map that supported
his decision by showing a higher crash rate where the work was being done.
At the same time, he showed the Department had already noted
the same location the public had identified.
(Pennsylvania)
Provides User Friendly Products – Maps enable the conveyance of information
effective to all levels of understanding.
They also are difficult to challenge.
The public at a meeting was willing to accept a map as justification
for a controversial decision.
Data QA/QC is made easy by spatial data, tools, and technologies. (
Pennsylvania)
Improves Customer Service – The some total of all the other benefits is
improved customer service.
The taxpayers are getting more productivity and better decisions for their
money. ( Pennsylvania)
Cartography/Mapping
The State Departmental Map utilizes Texas Department of Transportation’s
GIS centerline network to create the State Departmental Map in a shorter timeframe,
resulting in a time savings of 3 man-months and $15,000.00 annually.
(Texas)
District Control Section Maps can now be created in 3 weeks vs. 6 months,
using the GIS centerline map ($20,000 annually).
The Texas Department of Transportation’s GIS centerline map
when combined with the TRM database (Texas Department of Transportation’s
Linear Referencing System) is an invaluable tool for reviewing location data
visually. Other examples of thematic
maps generated from TRM include:
·
HPMS sample maps for 25 Districts to aid in HPMS field reviews.
·
HPMS-LRS portion of HPMS submittal will be done in Arc.
·
NHS Maps
·
STRAHNET Map (Texas)
Texas Department of Transportation’s Travel Map is being converted to a
GIS-based application. This
will allow the Travel and Information Division (TRV) to have an accurate
and current basemap for the 2.2 million copies of the Texas Travel Map printed
annually. A detailed explanation
of quantitative cost benefits for the TRV Travel Map project is detailed
below.
·
Decrease TRV FTE time spent in duplicating data maintenance efforts
($5,000/year)
·
Decrease TRV FTE time spent managing contract for manual cartography $2,000/year)
·
Discontinue existing contract for manual cartography services
($14,000/year)
·
Produce maps within the Division for use in other TRV publications
($10,000/year)
·
Produce maps within the Division for use in other travel business functions
$10,000/year) Total Cost Savings Per Year $41,000/year
·
Estimated savings for transfer of attribution of centerline route data to
TPP for use on Departmental map
($42,000/one-time investment)
·
Estimated savings for future HCR Web Site/GIS function/eKiosk projects*
($270,495/one-time investment)
·
Current estimated savings for rescribing entire Travel Map** ($468,560/one-time
cost) Total One-Time Cost Savings $781,055
*This savings is based on the transfer of technology and knowledge from
this project to those mentioned.
The total savings figure is the sum of hours spent in analysis and design
processes and processes related to creation of data layers.
Investment in analysis of current data flow, maintenance
and update cycles; design of effective data flow, maintenance and update cycles;
identification of additional data layers necessary; creation of additional
data layers; and development of in-house GIS knowledge will provide a solid
basis for future projects.
**This savings is based on the premise that If the map is not produced through digital cartographic means, it will be necessary in the near future to have the entire map rescribed using manual cartographic methods, in order to provide consistent map quality and to ensure the ability to continue to update and print new versions of the map. The estimated cost reflects current labor and production prices. It is expected that in the future, as persons with manual cartographic skills become more scarce, this cost will increase. ( Texas)
Previously,
the Department prepared most maps manually. Due to linkage capabilities
to real time information in the road inventory database, GIS enabled the
automated production of the Key Route, Structure Number, Rail/Highway Crossing,
and Functional Classification Maps.
These maps are used extensively by many functional areas in
the Department. In addition,
GIS provided the means to access the digitized corporate limits from the
Illinois Department of Revenue rather than each municipality individually
to obtain updated annexation information. One additional cartographic benefit
is the graphical display of annual changes in inventory information that
accelerated normal cartographic production.
For example, Cartographers are able to rapidly identify and
incorporate annual changes, such as road surface type, into the county map
series. ($310,000 estimated annual benefits). (
Illinois)
The Aerial Photography Index GIS project provides
a digital index of all existing aerial photography for the Aerial Surveys
Section. GIS enables a visual
graphic showing available aerial photography at any location in Illinois.
This information is displayed overlaying Digital Raster Graphic
quadrangle maps. Efficiency Benefits
result from a reduction in time of searching through mylar overlays to determine
aerial coverages for a specific area. ($55,000 estimated annual benefits).
(Illinois)
Annual/Multi-Year
Program Development
The Annual and Mull-Year Highway programs development process involves the
extensive use of information of a geographic nature to make decisions for
the selection and prioritization of roadway improvement projects.
This process also involved the development of maps for public
hearings and briefings with the executive office. GIS provides displays
and work products to enable program development and promote communications
between districts, the central office and executive management.
Efficiency Benefits result from the automated preparation
of maps displaying such items as project length and scope, legislative districts,
program years, pavement condition, accident information and structure status.
For Effectiveness Benefits, GIS enables the more efficient analysis and
compilation of information from the separate files for more effective programming
decisions. A major benefit
is the more efficient selection of roadway resurfacing projects based on
forecasted pavement condition resulting in increased pavement life and public
serviceability. ($340,000 estimated annual Efficiency Benefits, $2,000,000
to 4,000,000 estimated annual Effectiveness Benefits). (
Illinois)
Transportation
Data Analysis
View Data in a New Way – Management has been freed from analyzing data and
making decisions from tabular reports.
Spatial tools make it easier to comprehend a large amount of
data covering a wide geographic area. (
Pennsylvania)
GIS applications are being used to locate and track freight transfer facilities
and analyze rail-grade crossing safety information.
GIS has helped improve map products and perform studies quicker
and better than in the past. (Minnesota
)
Using GIS
in analyzing and mapping transportation project investments.
This has been key in helping them produce maps for the Statewide
Transportation Improvement Program (STIP). GIS has increased the quality of
the maps and reduced the amount of time to keep them updated. GIS has also
allowed them to get access to large amounts and many different layers of
data they couldn't get at easily in the past and it has improved their ability
to try more "what if's" and improved their ability to create exhibits to
aid in program discussions.
(Minnesota)
Increases Productivity – As we are automating tasks, realizing savings
on computer programming, and making better, informed decisions, we are getting
more ‘bang-for-our-buck.’ Staffs
are available for additional duties and priorities. (
Pennsylvania)
Organizational Communication
Currently using GIS to improve coordination between functional areas. In
big organizations such as Minnesota Department of Transportation, this can
be difficult. For example, the
functional area that completes pavement maintenance (such as mill and overlay)
was not communicating well with the functional area that is in charge of pavement
striping. There were times when
a road was striped with expensive durables (which should last years), only
to have a mill and overlay later that summer.
Communication with tables and textual information was not
enough. The GIS process takes
the Access database maintained by the striping area, generates a metro-wide
map as well as individual maps for each sub-area.
The maps are distributed to the functional areas that maintain
the pavement. This provides
better coordination of effort and reduces the amount of re-work, saving time
and money. ( Minnesota)
Currently using GIS to help locate radio tower placement and analyze options.
GIS has helped them improve their map products and perform their studies quicker
and better than in the past. ( Minnesota
)
Reduces Mainframe Programming – The Department’s GIS Database works like
a data warehouse. Regularly used
data items are extracted from legacy roadway, bridge, crash maintenance, and
project systems then put into a relational client server database.
The information can then be queried using standard SQL to
generate tabular reports. In
contrast, the traditional method of extracting this information from mainframe
database flat files requires programmer time.
Jobs fail, reports are difficult to format, and a programmer’s
time is impossible to get. (Pennsylvania
)
Internet Road Conditions
Traffic Management Center – Maryland’s CHART system uses GIS to both provide the traveling public with real time map displays of highway system conditions as well as in operations management by mapping the location of key resources (snow plows, emergency response vehicles) and depicting highway system conditions during weather related events. ( Maryland )
The Internet Road Condition GIS Project automates the geographical display
of various roadway condition data.
The Department already gathered roadway condition information
such as snow coverages, lane closures, construction activity, maintenance
activity and reduced height and weight restrictions.
Some of this information is updated on an hourly or daily
basis. The Department then
disseminated this information internally and to the public via various manual
maps and the Internet in computer text listings.
GIS enables the Intranet/Internet delivery of this information
in map form for winter road condition that is by far the most accessed web
page on the Illinois Department Of Transportation web site.
The map would also be more visually informational than simple
text listings of road conditions ($5,000 estimated annual benefits, intangible
benefits - improved public communications). (
Illinois) Maintenance And Operations
The Maintenance Division of the Texas Department of Transportation is using
a GIS application to generate the end-of-year statewide maintenance report
from Maintenance Management Information System (MMIS) data. It takes a couple
of weeks to create the report using GIS as opposed to up to 8 months to do
it with Microstation and Excel as was previously done. (
Texas)
GIS is currently used to help in snowplow routing, mapping weed control
areas, and conducting snowtrap/snowfence inventories. GIS is reducing the
amount of time it takes to prepare yearly snow plow route maps and makings
it much easier to update them as things change.
Using GIS for the snowtrap inventory is helping designers
and planners track problem areas and include mitigation efforts when a project
is in the area. They are also looking at other options like living snow fences
to reduce snowdrifts and ultimately the amount of maintenance effort needed
to keep the roads open for winter travel. (
Minnesota)
Maintenance is using GIS in two ways to help manage activities, they are
making maps of daily work activities and they are mapping results from the
database (facility maintenance) monthly and annually to get an overall picture
of the activities on the roadway. (
Maryland)
Previously, certain routine or seasonal tasks were labor intensive.
With the implementation of spatial data, tools, and technologies,
many of those tasks are handled in an automated fashion.
For example ‘Snow maps’ or winter service maps display each
snowplow run and municipal agreement in a county.
Maps are placed in each truck, maintenance shed, and as public
display. Before spatial data,
tools, and technologies, this task took several staff several days to create
by hand. Now one person can set
up the maps once and the application is mostly automated for subsequent years.
(Pennsylvania)
Right-Of-Way/Land Acquisition
Mapping
The San Antonio ROW Map Locator is a web application, currently in test-phase,
that serves digital scans of right-of-way maps to the public, thus freeing
up a FTE (full-time-equivalent) that previously had to run blue-lines all
day in order to comply with ad-hoc requests. (
Texas)
Currently using GIS to manage the department’s 1:24,000 base map. Staff
also uses GIS to integrate right-of-way information with project-specific
information to help in tracking and displaying the status of right-of-way
purchasing. (Minnesota)
Identifying Property Owners affected by a project - Having the State’s tax
map and assessment database as a GIS spatial layer has greatly reduced the
time to identify affected property owners and create a database for project
mailings. What used to take about
8 weeks for a major project now only takes about 4-6 hours.
(Maryland)
Construction
Currently using GIS to improve the project notification process. Minnesota
Department of Transportation needs to mail notification of upcoming projects
and other notices to people living in and around areas where construction
projects are planned. Previously
this was done by contacting each of the appropriate counties (and/or cities),
sending them a copy of the mailing area hand drawn on a copy of a Hudson's
map book page, and waiting.
The time frame and cost varied from county to county and from city to city.
The average time was three weeks, at a cost of around $.50
per parcel. This produced hard
copy mailing labels, which staff then had to manually affix to the flyers.
If the labels had a printing error (which occurred too often),
new labels had to be requested which meant another three week wait.
The GIS process brings the parcel data with the needed addresses
directly to the project manager. It now only takes a few minutes to generate
an electronic mailing list which is a savings in both time and dollars. (
Minnesota)
Recycled Materials Locator – This is a web application in development to
let Texas Department of Transportation contractors locate recycled construction
material generator plants. No
numbers available yet on time, cost savings. (
Texas)
The Material Supplier Location Mapping GIS project displays the location
of material suppliers throughout the state.
This includes bituminous plants, quarries, concrete plants
and pipe manufacturers. This
project also provides the ability to analyze material usage and inspection
patterns. Immediate Efficiency
Benefits resulted from the automated mapping of material supplier locations
that were previously manually mapped, CADD mapped or distributed in text form
($7,000 estimated annual benefits). (
Illinois)
Plans/Records Management
The District Records Management GIS project, currently under development in Illinois DOT, would improve the storage and accessibility of district records. This project would provide a listing of all project documents related to a particular roadway section or intersection. Eventually, records would be electronically linked to geography through access to GIS. The GIS stations for this project would be in daily use for accessing project records and for management use in assessing ongoing projects. Efficiency Benefits would result from a significant reduction in time for identifying and retrieving project records. Time-consuming manual searches, especially for historical referencing, would be greatly reduced. Potential Effectiveness Benefits would result from more rapid access to accurate information to improve decision making. Implementation of this project is not anticipated until fiscal year 2004 due to the complexity of the project ($900,000 estimated annual benefits). ( Illinois)
Permits
The Illinois Department of Transportation manages a roadway permitting process
for overweight and oversized vehicles that operate on the state highway system.
This process makes extensive use of roadway and structural
inventory information. A stand-alone
mainframe system currently accomplishes this process.
Roadways are referenced by marked routes and verbal descriptions
with permit routing directions issued in text form.
This GIS project will enable the graphical display of road
and structure network barriers to define efficient routing schemes with the
preparation of visual maps. Efficiency Benefits would result from an automated
visual analysis of the network and potential Intranet/Internet applications
($120,000 estimated annual benefits). (
Illinois)
Aeronautics
Currently using GIS to locate, display and analyze airfield data. GIS has
helped Aeronautics personnel improve their map products and perform their
studies quicker and better than in the past. (
