文章就动态三叉型交叉路口交通信号灯的调控进行了研究,提出一个实时的交通信号灯调控策略.该策略能根据检测和预测的交通状态信息,如车流量、车辆等待时间、车流密度等,进行交通信号灯顺序和时长的优化.利用Matlab软件对该方法进行了仿真实验,分析结果验证了该调控方法的有效性. In this paper, the control of traffic lights at dynamic trigeminy crossroads is studied and a real-time traffic light control strategy is proposed, which can make traffic control based on detected and predicted traffic status information such as traffic flow, vehicle waiting time and traffic density Signal sequence optimization and time optimization.Matlab software was used to simulate this method and the results verified the effectiveness of this method.
