The invention belongs to the technical field of traffic control, and particularly relates to a traffic signal control method and device, a computer readable storage medium and a terminal device. The method comprises the steps of in a vehicle-road cooperation scene, carrying out traffic signal control according to an initial signal timing scheme; when more than one bus priority request is received,executing a signal priority duration dynamic decision, wherein the signal priority duration dynamic decision is based on the phase structure and the phase sequence of the initial scheme; taking the green light durations of every two adjacent stages as optimization variables and the minimized weighted vehicle average delay as an objective function, determining the optimal switching time point between the current green light phase stage and the next green light phase stage; and performing traffic signal control according to the result of the dynamic decision of the signal priority duration. According to the present invention, the operation efficiency of buses and common social vehicles can be considered, and the optimization problem of bus signal priority duration dynamic decision is established, so that the maximum control benefit is obtained.
本申请属于交通控制技术领域,尤其涉及一种交通信号控制方法、装置、计算机可读存储介质及终端设备。所述方法在车路协同场景中,按照初始的信号配时方案进行交通信号控制;当接收到一个以上的公交优先请求时,执行信号优先时长动态决策,所述信号优先时长动态决策基于所述初始方案的相位结构和相序,以每两个相邻阶段的绿灯时长为优化变量,以最小化加权车均延误为目标函数,确定当前绿灯相位阶段和下一绿灯相位阶段之间的最佳切换时间点;按照所述信号优先时长动态决策的结果进行交通信号控制。通过本申请,可以兼顾公交车辆和普通社会车辆的运行效率,建立公交信号优先时长动态决策的最优化问题,从而获得最大的控制效益。
