The invention discloses an intersection traffic signal lamp timing method, and belongs to the technical field of intelligent traffic. The method comprises the following steps: detecting the real-time traffic flow of an intersection; based on a Webster delay model, calculating consistent delay time and random delay time of the vehicle; calculating the average delay time of the vehicles according to the consistent delay time and the random delay time of the vehicles; establishing a dynamic scheduling model by taking the minimum average delay time of the vehicles as a target function; and inputting the real-time traffic flow into the dynamic scheduling model, and solving the signal lamp distribution time when the average delay time of the vehicles is minimum. According to the method, the traffic flow under various conditions can be covered more comprehensively, and the calculation amount of the model is reduced.
本发明公开了一种路口交通信号灯配时方法,属于智能交通技术领域。所述方法包括:检测路口的实时车流量;基于韦伯斯特延误模型,计算车辆的一致延误时间和随机延误时间;根据车辆的一致延误时间和随机延误时间计算车辆的平均延误时间;以最小化车辆的平均延误时间为目标函数,建立动态调度模型;将所述实时车流量输入所述动态调度模型,求解出车辆的平均延误时间取最小值时的信号灯分配时间。本发明既可以更全面的涵盖多种情况的交通流量,又减少了模型的计算量。
