Transit Signal Priority Research Tools

摘要: This report addresses Transit Signal Priority (TSP) deployment issues. It reviews National Transportation Communications for ITS Protocol (NTCIP) 1211 Control and Prioritization (SCP) standards, defines five SCP scenarios, describes how the scenarios can be applied differently based on TSP priority operating policies. The provides an overview of a number systems, including centralized TSP, two discrete systems loop detection Global Positioning System (GPS) technologies, Adaptive (ATSP) system. A comparison different deployments, guidance necessary infrastructure required to implement these are provided. also discusses evaluation methodologies, recommended measures effectiveness (MOE’s) data performing quantitative assessment. Evaluations sites documented demonstrate benefits transit impacts traffic operations assessed using approaches. Finally, planning analysis methods, such as simulation regional modeling tools.
