Pilot Test of the TCAPP Collaborative Decision-Making Framework Including a Self-Assessment Methodology: Washington State’s SR 509 Project

TRB’s second Strategic Highway Research Program (SHRP 2) has released a report that describes the results of a pilot test of the Transportation for Communities—Advancing Projects through Partnerships (TCAPP) collaborative decision-making tool as part of the Washington State Department of Transportation’s (WSDOT) I-5/SR 509 Corridor Completion and Freight Improvement Project. TCAPP is now known as PlanWorks.

TCAPP is designed to provide agencies and practitioners with guidance on reaching collaborative decisions as they work through the traditional transportation planning, programming, and permitting processes.

Other pilot tests were conducted in Colorado, Minnesota, and Washington State.
