Summary Information

Background
Transit preferential treatments have been deployed across the United States and around the world in order to improve travel times and reliability of bus and light rail routes. Examples of transit preferential treatments include exclusive lanes and median transitways, transit signal priority, queue jumps and bypass lanes, curb extensions, and stop consolidation. The costs of transit signal priority (TSP) systems are reported below. These costs are from a synthesis report on Bus and Rail Preferential Treatments in Mixed Traffic, conducted as part of the Transit Cooperative Research Program, and as such, the costs are compiled from multiple deployment locations.
