A real-time, decentralized, smart and scalable, adaptive traffic signal control system that optimizes and coordinates highly dynamic traffic flow in complex (grid-like) urban road networks. Here it is applied to the tight-coupled intersections at Pittsburgh, PA. The simulation shared the same core control engine with the field implementation of surtrac smart traffic lights that saved the average travel time over 25%.
The core control engine of Surtrac includes schedule-driven intersection control (SchIC) [1] and decentralized coordination mechanisms [2].
