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.
