【摘要】 为改善传统主干线协调控制方法中存在的问题,对传统主干线协调控制算法进行了深入的研究和改进。改进算法为有效提高绿时利用率,减小车辆延误,对单路口实施了改进的模糊控制算法;同时,对主干线上车辆到来情况进行实时检测,若有大规模车队到来,则中断模糊控制器,即时疏散车队,从而实现对主干线的实时协调控制。将此算法应用于城市主干道交通协调控制,对减小整个主干线的停车延误和排队延误有很好效果,并且对路况变化具有较强的鲁棒性,适合在大中城市中推广。更多还原

【Abstract】 Urban main road coordinate control problem in intelligent traffic system is discussed. An algorithm is presented to increase the efficiency of the green time and reduce the traffic delay, by using the improved fuzzy control algorithm in each intersection. Meanwhile, the coordinate control on the urban main road is realized by interrupting the fuzzy controller, when mass vehicles come from the main road. The simulation shows that the algorithm can improve the traffic condition of the whole road successfully, and it is robust to the changing of the environment.更多还原
