为提高过饱和交叉口通行能力及免交叉口溢流,首先设计了动态相位组合及相序确定流程,在此基础上分析确定了过饱和交叉口信号控制关键参数,并采用集散波理论与模糊控制相结合的方式,对过饱和交叉口信号控制问题进行了研究,最终形成饱和交叉口分布式关联控制方法.仿真结果表明,本文方法能够有效地抑制过饱和交叉口溢流现象的发生,并能够减少车辆在单个路口的平均延误时间. In order to improve the traffic capacity of the intersection and the intersection-free overflow, the dynamic phase combination and phase sequence determination are firstly designed. On the basis of this, the key parameters of the signal control of the supersaturated intersection are analyzed and determined. Control, the signal control problem of supersaturated intersection is studied, and finally a distributed correlation control method of saturated intersection is formed.The simulation results show that this method can effectively restrain the occurrence of overflow at supersaturated intersection Can reduce the average delay time of a vehicle at a single intersection.
