Transit signal priority: a regional implementation

The authors describe how all parties in the Puget Sound advanced traffic management system implementation project evaluation process recognized the need for collaboration at the outset in educating one another of the interests of transit operations and urban traffic control. This collaboration continued through formal recognition of a multi agency, multidisciplinary proposal selection board to develop the system configuration and request for proposals details ans specifications, as well as participate in proposal evaluations and recommendations. It was to the benefit of all parties that the up front planning time and dedicated consensus building was necessary for successful implementation and regional acceptance of the system.
