Study of intersection control under saturated traffic flow based video detection

摘要

The typical intersection traffic flow control ways play poor role in saturated status, in order to resolve this problem, at first, the intersection control features under saturated status is analyzed, then by the queue length detection by video detection way, a new control way with threshold and rule is put forward, in which three control stages are included. Simulation result shows that this method has more effectiveness than the Webster's method when traffic flow is saturated.
