摘要：AbstractIn oversaturated condition, traffic queues that are unavoidable persist from cycle to cycle and the queue management capability is a critical feature in signal control. Inappropriate signal control and queue management strategies may lead to spillover and starvation with serious disruptive consequences. Compared with minimizing delay and stops in uncongested condition, the control policy in oversaturated condition comes to maximize system productivity and fully utilize storage capacity. This paper describes one dynamic control model to adjust the green phase duration, offset and cycle length by considering the saturation level, the queue length management and propagation along the arterial corridor. A VISSIM simulation test of one arterial corridor in City of Edmonton is used to validate the efficiency of the proposed control model.
