Traffic Analysis Tools

The Traffic Analysis Tools Program was formulated by FHWA in an attempt to strike a balance between efforts to develop new, improved tools in support of traffic operations analysis and efforts to facilitate the deployment and use of existing tools. FHWA has established two tracks under the Traffic Analysis Tools Program: the deployment track and the development track.

Deployment Track

This track concentrates on the needs and concerns of the traffic analysis stakeholder community:

Development Track

Focuses on enhancing and developing models that are easier to use, more robust in their application, and more reliable in their results. Read more about the Models.

Through the FHWA Traffic Analysis Tools Program, our partners and customers will expand their use of analysis tools and innovative analysis approaches that consider a system-level approach and will enhance mobility. They will gain insight on recommended/best practices and lessons learned in operational analysis. They will gain a high level of confidence in utilizing the analysis tools for their local needs. The proactive role from FHWA, will enable analytical tools and decision-support systems to reach their full potential to support a viable transportation community in a manner sufficient to make a significant contribution to evolving traffic congestion and management problems.
