Traffic signal control for arterial intersections based on flow control of window-advertisement
窗口流量控制的干线动态协调控制方法

The traffic in arterial intersections is usually over-saturated; and gridlock occurs very frequently in rush hours. In order to improve the efficiency of traffic flow control and prevent the arterial system from traffic jam, we propose a method for analyzing the available bandwidth to supervise states of the arterial traffic signal control system. On this basis, we promoted by the idea of window flow control in TCP/IP, present a scheme of traffic signal control for arterial intersections to reduce traffic congestion. Simulation demonstrates that the downstream intersections are continuously providing their effective capacity to the upstream intersections through the flow window; by this information and the current traffic demand, the upstream intersections assign green time to each traffic stream accordingly.
