There have been countless efforts directed toward efficiently controlling the flow of vehicular traffic through an intersection. This paper describes an algorithm designed for the signal control problem that employs concepts drawn from the field of packet switching in computer networks. The novel method proposed utilizes a maximal weight matching algorithm(More)

A significant amount of delay to transit vehicles in urban areas is caused by traffic signals. Implementation of signal priority has the potential to reduce control delay caused by traffic signals. The implementation of these systems requires engineering studies that address both transit and traffic signal operations. A comprehensive program requires(More)
In the next millennium, traffic signal systems will need to address many issues, spanning a broad range of technical, social, and political boundaries. With the increase in urbanization and traffic congestion comes a greater demand to operate our roadway systems with maximum efficiency. As traffic volume continues to increase, roadway capacity will increase(More)
Transit Signal Priority (TSP) is an operational strategy to facilitate the movement of transit vehicles through signalized intersections. It is typically done by giving transit vehicles an extended green or reduced red at signalized intersections under certain pre-defined conditions (e.g., late arriving buses only). This allows for more reliable travel(More)
