A distributed optimum signal scheme for dynamic traffic control

In this paper, a prototype named distributed optimum signal scheme (DOSS) is introduced. DOSS solves the generally recognized network-wide signal optimization problem using an algorithm based entirely on dynamic programming. It has been implemented and evaluated in a simulation testing environment, and the simulation results indicate significant improvements compared to a well-timed fixed-time control and an actuated signal. DOSS fully exploits a microscopic simulation technology. It is designed to provide a feasible computational framework applicable to dynamic traffic control (DTC) in conjunction with Advanced Traffic Management Systems (ATMS) and Advanced Traveler Information Systems (ATIS).
