The technical problem to be solved by the invention is to provide a crossroad traffic signal lamp time adaptive adjustment method. The method comprises the steps that a traffic flow observer monitorstraffic flow information of straight going and left turning in each direction of a crossroad in real time, and inputs the information into a controller; the controller receives the flow information ofvehicles going straight and turning left in all directions at the crossroad in real time, takes vehicle retention information (estimated by the controller according to the previous lamp time and thetraffic flow) of each intersection and the traffic flow information of each direction as input conditions, applies an improved genetic algorithm, takes the minimum vehicle retention at each intersection as an optimization target, and optimizes straight going and left turning lamp time of each direction; and the controller sends an optimal lamp time distribution scheme to the traffic signal lamps respectively, so that adaptive adjustment of the traffic signal lamps is realized, and the purpose of minimizing vehicles left at each intersection is achieved. According to the method, the structure is simple, and traffic jam can be effectively relieved.

    本发明专利要解决的技术问题是提供一种十字路口交通信号灯时自适应调节方法,通过交通流量观测器实时监测十字路口各向直行和左转的车辆流量信息,并将信息输入控制器;控制器实时接收十字路口各向直行和左转车辆流量信息,以各路口车辆滞留信息(控制器根据上一个灯时以及车流量估算)和各向车流量信息为输入条件,应用改进遗传算法,以各路口滞留车辆最小为优化目标,进行各向直行和左转灯时优化优化;控制器将最优灯时分配方案分别发送给交通信号灯,实现了交通信号灯的自适应调节,达到各路口滞留车辆最小的目的。该方法结构简单,可有效缓解交通堵塞。
