U.S. Department of Transportation
Research and Innovative Technology Administration
Background
Influenced by several different efforts:
 In 2008, an “issues brief” by NSGIC called for the creation of TFTN
 OMB Circular A-16 identifies the USDOT as the “lead agency” for
the “transportation theme” of the National Spatial Data Infrastructure
(NSDI).
 Emerging USDOT data requirements for geospatial data for all
roads, such as accident reporting for enhanced safety and bridge
inventory.
 Aligned with several initiatives such the emerging federal
Geospatial Platform concept. - one element of the “geospatial
portfolio”

TFTN Concept
“Creation and maintenance of high-quality, nationwide
transportation data that is in the public domain”
□ An initial focus on street centerlines, but eventually multi-modal
□ Nationwide data spanning all states and territories
□ All roads, not just Federally funded roads
□ Provides a common geometric baseline
▪ Road naming
▪ Persistent segment ID numbering
▪ Advanced functionality is built on top of baseline
□ Data is in the public domain and readily shareable

4
Strategic Planning Effort - History
RITA/BTS agreed to fund and manage the effort
Funds obligated and contractor selected in October 2009
□ Koniag Technology Solutions
□ Applied Geographics
Suffered through many contracting glitches associated
with “end-of-year” money
Contract finally awarded in March 2010

5
Strategic Planning Effort – The Process
Identify and engage stakeholders
Define requirements, challenges and opportunities
Document progress already made
□ Existing Datasets
□ Best Practices
□ New Ideas
Explore implementation issues
Evaluate funding sources

6
Stakeholder Outreach - Presentations &
Workshops

7
Stakeholder Outreach - Interviews
• Safety
• Highway Performance Management System
• Intelligent Transportation Systems
• Asset Management
• Deputy Director of RITA

8
Trends from the Workshops and Interviews
 Near Unanimous Support
□ All of those interviewed and most of those who attended the
workshops have indicated their support for this effort
 Learned of a number of similar efforts underway that
benefit from TFTN
 Safety could be a key to the success of TFTN
□ A geospatial representation of ALL ROADS is needed to meet
many of the USDOTs Safety Initiatives
□ A geospatial representation of ALL ROADS is needed for
emergency response
□ Lots of federal money for safety initiatives

9
Trends from the Workshops and Interviews
 “Think Regionally Act Locally”
□ States and counties are beginning to look beyond their borders
□ States and counties are the authoritative data source for their
transportation data
 “Can you live with that?”
□ The Stakeholders have different needs
□ Need to find a baseline that works with everyone
□ Once the baseline is established, the consumers can add their
own “special sauce”

10
Baseline Geometry with “Special Sauce”
 The specifics of what’s included in “baseline geometry”
requires further definition
 Initial, minimal components might be:
□ Road naming
□ Basic attributes (e.g. functional classification)
□ Persistent segment ID numbering
 Seeking additional ideas and input from stakeholders on
what’s feasible
 “Special sauce” can be content and/or capabilities

11
Variety of stakeholders adds their own “special
sauce” on top
•TFTN: Common baseline foundation
of geometry, basic attributes
•State DOTs: Linear Referencing System (LRS)
•State DOTs: advanced attributes
•Private Sector: full routability and
immersive imagery
•USGS: Enhanced cartographic display and
labeling
•US Census: Polygon topology for census
geographic units
•State E911: Addresses

12
A Potential Model for TFTN - HPMS
 FHWA reporting requirements for the Highway
Performance Monitoring System (HPMS) include the
submission of a geospatial network of all Federal-aid
roads by each State DOT
 Current reporting requirements for the HPMS could be
expanded to require all roads
□ Detailed HPMS attributes would continue to be provided for only
Federal-aid roads
□ Annual nature of HPMS reporting provides a data update
mechanism
□ USDOT works with states to develop basic standards
□ Reporting requirement would enable states to utilize FHWA
funding for creation and maintenance of inventory

13
Obstacles Associated With This Model
 FHWA has to change the HPMS Reporting
Requirements to include all roads in the geospatial
submission
 States are not required to work with neighbors for
connectivity
 No USDOT resources currently available for
aggregation, assembly and publication of a nationwide
data set
 The level of quality/accuracy varies from State to State

14
Potential Vision for TFTN
ProduceCatalyze &
Standardize
Aggregate
& Publish
USDOT
via HPMS
• HPMS annual reporting requirement
• Opens funding
• Develops standards
• Products support broader US-DOT
business needs, such as Safety
• Ability to provide funding support to
local entities
US Census
via TIGER
• Existing, branded product
• Existing staffing resources for
nationwide data integration
• Expertise in nationwide data
assemblage
• Expertise in nationwide data
publishing
OpenStreetMap
Opportunity for
authoritative sources
to detect data

Potential Benefits of TFTN
Different benefits to different groups of stakeholders

16
Examples of what have we heard so
far…

17
At the ESRI User Conference
 Short-term and long-term considerations
□ Short term: don’t forget several nationwide datasets currently exist
▪ TIGER
▪ Commercial
▪ OpenStreetMap
□ Longer term: design and build something new
 HPMS is not resourced to make a seamless nationwide data
set
□ Look at other “process models” too!
□ Public/private partnership
□ Build on TIGER
□ Volunteered Geographic Information (VGI)
□ Something “outside-the-box” that we have yet to imagine

18
Census Bureau Interview Takeaways
 TIGER is a mature product
□ Many users depend on it for a variety of applications
▪ National broadband mapping (for Census geometry)
 Significant improvements in latest TIGER files
□ Positional accuracy improved (7.6 meter)
□ Substantial input from local sources incorporated
□ Research into potential for OpenStreetMap
 Planning for more frequent updates (depending on funding)

19
USGS Interview Takeaways
 Requirement for nationwide roads in The National Map
(TNM)
 TIGER did not meet TNM requirements
□ Positional accuracy
□ Depictions of interchanges and dual-carriageways
□ Attributes
□ Costs to retrofit TIGER were prohibitive
 Have currently replaced TIGER with TeleAtlas data
□ Competitive price, but restricted use
□ Looking at OpenStreetMap and other alternatives, long-term
 The National Hydrography Dataset (NHD) provides a
positive example of Federal-State collaboration

20
At the NSGIC Annual Conference
 Develop a matrix of common requirements and approaches
– “what are the shared needs and commonalities?”
 Develop an inventory of what each state has for statewide
street centerlines
 Develop several success stories as 1-2 page fact sheets,
perhaps as “tiered” levels of success
 The Census Bureau considers itself to be a “Data
Integrator,” not a Data Producer per se; boundaries are the
“real issue” for Census Bureau, not roads; DOTs might
need greater detail
 Next Generation 911 is and will be a big driver for GIS-
based initiatives to build statewide street centerline data
sets to support automated routing

21
GIS Pro Takeaways
 Data Sharing is two way relationship
□ “Co-dependency” can lead to success
 Increased involvement in planning process from local government
stakeholders is desirable
 Public/Private Partnership: “knotty issues” of licensing will need to
be addressed.
□ 2004 study from National Academy of Science titled “Licensing of
Geographic Data and Services” could be a resource.
 Needs to be an emphasis on identifying what is in the core,
common base of TFTN (vs. special sauce).
□ US Census pointed to “Federal Survey” of 19 agencies that identified their
common needs as a starting place.
 Baseline data elements should not be complex; added complexity
can affect the success of the project

22
The Road Ahead
 More interviews, meetings, surveys, case studies, etc.
 Through these, we will:
□ Identify what’s working, what’s needed – current practices,
requirements, strategies, standards, documentation
□ Identify institutional constraints, capacity, operational authority,
motivation, benefits, etc.
□ Formulate strategies for implementation
□ Identify potential sources of funding
