Welcome to TRAC


The Washington State Transportation Center (TRAC) is a cooperative, interdisciplinary transportation research agency.

Its members, Washington State University (WSU), the University of Washington (UW), and the Washington State Department of Transportation (WSDOT), formed TRAC in 1983 to coordinate transportation research efforts—both state and commercial, public and private—and to develop research opportunities both nationally and locally. TRAC acts as a link among government agencies, university researchers, and the private sector.

TRAC researchers conduct projects in the areas of

Bridges and structures
Construction management
Ferry systems
Freeway and arterial management
Freight transportation
Geotechnical engineering
Health and transportation
Highway design and safety
Intelligent transportation systems
Knowledge management
Multimodal travel
Technolgy transfer
Traffic engineering
Transportation planning
Vehicle design and operation.

Please see the 2012-2013 TRAC Biennial Report to read about our most recent projects. For a paper copy, contact our main office at 206-543-8690 or trac@uw.edu.
