摘　　要：交叉口作为城市交通系统中的重要节点,其运行效能的优劣直接影响到整个路网的交通顺畅度。对此,本文结合交通信号灯控制系统发展现状,提出一种面向区域路网的信号灯协调控制策略。以Webster相位配时算法为基础,通过基于VISSIM软件的仿真实验,发现该策略能够利用区域路网的车流量分布逐级确定绿波干道并对绿波干道所在的交叉口相位进行时差调和,使其形成理想的绿波带。对比固定配时策略和基于单一路口的信号灯动态配时策略,本文提出的基于区域路网的信号灯协调控制策略能够降低车辆延误,提升路网通行效率,可以为城市智能交通信号灯的建设提供参考。As an important node in urban traffic system,intersections have a direct impact on the traffic smoothness of the whole road network.Based on the current situation of traffic signal control system,this paper proposes a coordinated control strategy of traffic signal based on regional road network.Based on Webster phase timing algorithm,through the simulation experiment based on VISSIM software,it is found that the strategy can make use of the distribution of regional traffic flow to determine the green wave road step by step and coordinate the phase of the intersection where the green wave road is located,so as to form an ideal green wave belt.Compared with the fixed timing strategy and the dynamic timing strategy of signal lights based on a single intersection,the coordinated control strategy of signal lights based on regional road network proposed in this paper can reduce vehicle delay and improve road network traffic efficiency,and can provide a reference for the construction of urban intelligent traffic lights.
