The invention discloses a traffic light dynamic timing method, which comprises the following steps of: 1, setting an initial timing scheme and a timing period; 2, reading traffic condition data of each intersection; 3, acquiring the number of queuing vehicles every two seconds in each lane group detection region; 4, calculating the difference between the number of queuing vehicles in each lane in a current timing period and the number of queuing vehicles in the lane in a previous period; 5, calculating the sum of the difference values of the number of the queuing vehicles in each lane, and dividing the difference value of the number of the queuing vehicles in each lane by the total difference value; and 6, adjusting the green light duration corresponding to each lane to be the product of multiplying the original green light duration by 1+a ratio of the difference values of the number of queuing vehicles. The invention further discloses a traffic light dynamic timing system, which comprises an initialization module, an identification module, a detection module, a calculation module, and a dynamic timing module. According to the traffic light dynamic timing method and the traffic light dynamic timing system, the traffic light timing scheme can be adjusted in real time according to the traffic flow condition so as to accurately manage the intersection traffic in real time, and the method and the system can be widely applied to the field of intelligent traffic.

    本发明公开了一种交通灯动态配时方法,步骤如下:1:设置初始配时方案和配时周期;2:读取各个路口交通状况数据;3:获取各个车道组检测区域每隔2秒的排队车辆数;4:计算当前一个配时周期内各个车道的排队车辆数与上一个周期内该车道的排队车辆数的差值;5:计算各车道排队车辆数差值之和,再将各车道车辆排队车辆数差值除以总差值;6:将各车道对应绿灯时长调整为原绿灯时长乘以1+排队车辆数差值比率。本发明还公开了一种交通灯动态配时系统,包括:初始化模块;识别模块;检测模块;计算模块;动态配时模块。本发明能够根据车流量情况实时调整交通灯配时方案,以精准、实时地对路口交通进行管理,可以广泛应用于智能交通领域。
