Transit Signal Priority in the Boston Region: A Guidebook

Posted 1/19

This guidebook consolidates national best practices and the experiences of local staff in planning and implementing transit signal priority (TSP). TSP is a strategy to reduce delays to transit vehicles at traffic signals to reduce transit travel times and improve transit reliability. Although many entities in the Boston region are participating in efforts to implement TSP, it can be a challenge to communicate and coordinate a project across the various agencies involved. Moreover, while resources, case studies, and best practices about TSP are available from across the country and around the world, there has been little documentation of TSP planning and implementation experiences in the Boston region.

The guidebook contains the following:

  • An introduction to TSP, including an overview of the benefits of TSP
  • A summary of existing and planned TSP projects in the Boston region
  • Metrics that planners and officials can use to identify and prioritize potential intersections for TSP
  • Information on the process of inventorying signal timing data, field equipment, and communications infrastructure in preparation of designing a TSP system
  • Information on how to create a system that takes advantage of existing equipment, some of the techniques that can be used to prioritize transit vehicle movement, and an overview of costs that have been observed for TSP projects in the United States and Canada
  • Metrics that planners and officials can use to evaluate the performance of implemented TSP projects
  • Keys to success that highlight strategies and themes to consider when working on TSP projects
