Traffic Analysis Roundtable

The Traffic Analysis Roundtable (TAR) brings state departments of transportation and the Federal Highway Administration (FHWA) together to solve shared traffic analysis challenges, advance practical research and strengthen the use of emerging tools, data and methods.

Led by the Colorado Department of Transportation and supported by FHWA, TAR is a national Transportation Pooled Fund (TPF) study, TPF-5(578).

How TAR Works

Working together to advance traffic analysis

TAR helps participating agencies pool knowledge, expertise and resources to address challenges that are difficult to solve alone by:

  • Identifying shared priorities

    Members name common traffic analysis needs and emerging challenges.

  • Advancing practical research

    TAR coordinates research and resources on priorities that benefit many states.

  • Sharing knowledge and building capacity

    Members exchange practices, tools and expertise through research, peer exchanges and training.

A national community of practice

TAR connects state DOTs, FHWA and transportation professionals to exchange knowledge, address shared technical challenges and strengthen traffic analysis practice.

Participating agencies: Colorado DOT (lead), Kentucky, Maryland (MDOT SHA), Michigan, Missouri, Nevada, Ohio, Oklahoma, Texas, Virginia, Washington and Wisconsin, with the Federal Highway Administration.
