The invention discloses a road intersection traffic signal lamp signal timing optimization method and system. The method comprises the following steps: acquiring vehicle passing data of a current road intersection and vehicle passing data of a previous road intersection; judging whether the current traffic flow generates a collective wave scene or not; if the aggregated wave scene is generated, judging whether the aggregated wave scene is generated after a set time range from the lighting moment of the green light or generated at the lighting moment of the green light; if yes, determining a first phase difference of the traffic signal lamp according to the acquired data; if yes, determining a second phase difference of the traffic lights according to the acquired data; if the aggregation wave scene is not generated, determining a third phase difference of the traffic signal lamp according to the acquired data; and according to the determined first phase difference of the traffic signal lamp, the determined second phase difference of the traffic signal lamp or the determined third phase difference of the traffic signal lamp, performing retiming on the traffic signal lamp of the current road intersection, and outputting a retiming result.

    本发明公开了道路交叉口交通信号灯信号配时优化方法及系统,获取当前道路交叉口的车辆通行数据和前一个道路交叉口的车辆通行数据;判断当前车流是否产生集结波场景;如果产生集结波场景,就判断集结波场景是距离绿灯亮起时刻设定时间范围之后产生的,还是绿灯亮起时刻产生的;如果是前者,则根据获取的数据确定交通信号灯的第一相位差;如果是后者,则根据获取的数据确定交通信号灯的第二相位差;如果未产生集结波场景,则根据获取的数据,确定交通信号灯的第三相位差;根据已确定的交通信号灯的第一相位差、交通信号灯的第二相位差或者交通信号灯的第三相位差,对当前道路交叉口的交通信号灯进行重新配时,输出重新配时结果。
