Washington State Department of Transportation

In 1983, WSDOT, the University of Washington, and Washington State University formed a partnership that established TRAC. TRAC provides a link among the government, university researchers, and the private sector. For WSDOT, TRAC acts as a liaison, connecting those who need applied research with those at the universities best suited to conduct it.

WSDOT’s Research & Library Services Office hosts Webinar Wednesdays, a series of bimonthly, one-hour webinars highlighting WSDOT research results. Each webinar showcases a research project whose results could eventually be implemented statewide or in other states. Since March 2017 this popular program has covered a wide range of transportation topics, from engineering to the environment, construction to conservation, and policy to preservation.
