Description
Transit Signal Priority (TSP) is an operational strategy that facilitates the movement of transit vehicles, either buses or streetcars, through traffic-signal controlled intersections. As transportation demand increases various transportation networks are facing increasing congestion. To mitigate the high-density impact of congestion on transit operations, TSP is a significant solution and has been widely applied to improve transit service quality and increase bus ridership. TSP can be planed and implemented considering many variables to achieve several valuable benefits such as: reducing transit travel times, better schedule adherence, and better transit efficiency. The objective of this research is to develop warrants and performance standards for transit agencies to implement signal priority based on identified decision factors. The research assesses existing guidelines and provides new guidelines for TSP implementation. Furthermore, this research evaluates the effectiveness of TSP in improving the performance of public transportation bus lines. The improvements are assessed by comparing the total travel time and total delay on the same single corridor with and without TSP applied utilizing microscopic analysis. The results show significant improvements in reducing the travel times and delays for the buses as a result of applying the TSP.
