Improved Traffic Signal Priority for Transit

Traffic congestion and traffic signals cause significant delay and increase operating costs for on-street transit service. Signal priority has been a promising method to improve transit operations and service quality, but it has not seen widespread deployment in North America. The resistance to implementation has often been based on a concern that overall traffic performance may be unduly compromised when signal timing, intended to optimize traffic flow, is overridden to provide a travel advantage to transit vehicles. The objective of this project is to develop and test improved transit priority algorithms for traffic signal controllers and systems taking into account various levels of hardware sophistication, operating characteristics, and transportation management strategies.
