对局部交通拥挤的干道,传统的干线绿波协调控制效果不佳。本文研究了一种对信号相位动态配时的协调控制方法,通过考虑停车线前的排队数及下游路段的有效容量来优化绿灯时长、相位差。采用遗传算法对其进行求解,并使用VISSIM对干线进行仿真验证。结果表明,该方法有利于局部拥挤的疏散。
On the part of the traffic congestion in the trunk, the traditional trunk green wave coordination control effect is not good. In this paper, a coordinated control method of dynamic timing of signal phase is studied. The green light duration and phase difference are optimized by considering the number of queuing before stopping line and the effective capacity of the downstream link. The genetic algorithm was used to solve the problem and VISSIM was used to simulate the trunk line. The results show that the method is conducive to local congestion evacuation.
