Abstract:The District Depart of Transportation (DDOT) is designing and implementing a transit signal priority (TSP) system at over 190 signalized intersections where many project intersections are located within the downtown core area. This will be the first major bus TSP implementation in an urbanized and grid system in the United States. Most TSP systems are applied to linear roadways, and therefore there is knowledge gap nationally on the effects of multiple bus routes and multiple TSP calls on traffic in a downtown roadway network. This project will develop a microsimulation model of a portion of the study area to assess, test, and refine TSP strategies in a dense urban environment. The simulation will assess the application of the District’s McCain traffic signal system and how TSP affects system operations within the roadway network.
