Current Funding/Program Status
All in-process work is fully funded
No additional dedicated FHWA funding expected for
NGSIM
What does this mean for the future of NGSIM?
Considerations for Looking Forward
The FHWA NGSIM program is a recognized success story
• Transforming FHWA from market competitor to market
facilitator
• Providing high-quality trajectory data sets and new
algorithms to address long-standing issues in congestion
modeling
• Facilitating collaboration between users, modelers and
software vendors
Long-term preservation of NGSIM momentum requires
revisiting the nature of the FHWA role and the
organization of the NGSIM community
• Current top-down, FHWA-funded model will not be sustained

NGSIM Next Steps:
High-Level Options
Option 1: FHWA Funds, Leads
• Continue under current funding and organizational structure
– option not viable without new funding
Option 2: FHWA Walks Away
• Sends a signal to the market that FHWA is no longer
interested in fundamental simulation fidelity
• NGSIM assets (data sets and algorithms) potentially lost
Option 3: NGSIM Community
• Deploy some current NGSIM funding to establish a selfgoverning, self-sustaining community
• Preserves current assets and community connections
• Provides opportunity for future simulation-related data sets
and algorithms

Why Pursue NGSIM Community Option?
NGSIM program is proven and mature, but there is
more work to be done
• Additional dataset and algorithm needs – recurring and nonrecurring congestion
• Untapped potential to significantly improve transportation
analyses and decision-making
• NGSIM is in an efficient “product development” mode
NGSIM has broad support from simulation
community to continue
Opportunity to leverage existing FHWA investment in
NGSIM for long-term benefits to decision-makers

Proposed NGSIM Community:
Principles for New FHWA Role
Provision of NGSIM core functions
• Staffing for organizational activities will not be FHWA-funded
• Repository and tool management will not be FHWA-funded
• FHWA will become community member, not community director
Accommodating new simulation-related research
• Algorithm development and dataset collection will not be funded
from an NGSIM-specific FHWA program
• NGSIM provides permanent home for quality data sets, algorithms
developed under an umbrella of potential funding sources
− NCHRP/TCRP, SHRP-II, UTC, non-NGSIM FHWA programs
− NGSIM-organized partnerships
• NGSIM provides mechanism to promote simulation-based research
by issuing simulation research needs

NGSIM Community:
Strawman Organizational Structure
Self-governing, self-sustaining model
• Community members are individuals, not organizations
• All community functions are performed by members
− No cost to join
− No remuneration (from the community itself) for participation
− No funding passes through community structure
• No FHWA veto power, community is self-governing
• Community leadership roles based on meritocracy:
“those that do, lead”
Organization structure based in part on successful
models from Information Technology field
Transitioning to NGSIM Community:
Proposed Next Steps
Community outreach and refinement of vision
(winter/spring 2007)
• Presentation at NGSIM meeting at TRB
• White paper on proposed organizational structure in Spring 2007
NGSIM Stakeholder Conference (spring/summer 2007)
• Gain consensus on community structure
• Develop community management by-laws
• Reprioritize algorithm and dataset needs
Develop NGSIM-UTC Partnerships (2007)
• Region X UTCs (Idaho, Washington, and Oregon) developing
Signalized Intersection Behavior Algorithm
• Develop additional NGSIM-UTC partnership opportunities
Full transition to NGSIM community by fall 2008
