TITLE: Preferential Signal Control Strategies for Transit Vehicles

Abstract: Transit priority is one form of preferential traffic signal control strategies provided to facilitate the flow and passage of transit vehicles including buses and rail cars. Transit priority requests are often conditional and may, for example, be granted on one or more conditions such as the absence of a pedestrian phase, the presence of a green interval, and a prescribed level of bus occupancy or degree of bus lateness.  A trend taking place is to coordinate the planning and deployment of transit priority and other preferential strategies for emergency vehicles for the purposes of developing a single, integrated traffic signal control system.
This presentation will focus on experiences and lessons learned in the U.S. and abroad in the planning and deployment of such preferential control strategies. The presentation will draw from research conducted on actual operational field tests as well as simulation analyses. 
This series is organized by the UMASS Amherst INFORMS Student Chapter. Support for this series is provided by the Isenberg School of Management, the Department of Finance and Operations Management, and the John F. Smith Memorial Fund.
