• Abstract:
  Transit signal priority (TSP) is an operational strategy that facilitates the movement of transit vehicles through signal-controlled intersections. Transit vehicle delay can occur for many reasons including traffic congestion, passenger boarding and alighting, traffic signal operations, and other factors but TSP is specifically aimed at reducing delay caused by signal operations. Connected vehicle, or vehicle-to-everything (V2X), technology was deployed on UTA buses and at signalized intersections, thus enabling “smart” TSP on Redwood Road in Salt Lake County (Route 217) and along the UVX bus rapid transit (BRT) line in the Provo-Orem area of Utah. One way to maximize the efficiency of new V2X deployments is to consider locations where TSP will provide the greatest potential benefit to buses; that is, intersections where buses experience large amounts of delay. This research analyzed bus AVL data recorded every 10 seconds for UTA's 17 core routes and counted how often buses stopped at signalized intersections. Results are compiled by individual intersection, transit route, and highway corridor. These findings will help inform UTA's and UDOT's prioritization scheme for new V2X deployments by providing a data-driven and needs-based approach to Utah's V2X planning and deployment practices.
