According to the traffic signal lamp dynamic timing method and device, the passing time of the current phase and the next phase of the traffic signal lamp is dynamically controlled according to the real-time traffic flow data of the current phase and the next phase and the green light execution time of the current phase. In the dynamic timing mode, according to the green light execution time of the current phase, the traffic flow of the current phase and the traffic flow of the lower phase, whether the signal lamp executes the instruction of the next phase is controlled, the green light execution time of the current phase is larger than the minimum green light time, and the traffic flow of the current phase is zero; and when the traffic flow of the next phase is greater than zero or the green light execution time of the current phase is equal to the maximum time of the green light, controlling the signal lamp to execute the instruction of the next phase. According to the traffic signal lamp dynamic timing method and device provided by the invention, the waste of traffic signal lamp resources is solved, the idle time of the traffic signal lamp is reduced, and the traffic efficiency of an intersection is effectively improved.

    本发明的一种交通信号灯动态配时方法及装置,根据当前相位和下一相位的实时车流量数据和当前相位的绿灯执行时间,动态控制信号灯当前相位与下一相位的通行时间。动态配时模式时,根据当前相位的绿灯执行时间、当前相位车流量、下相位车流量的大小,控制信号灯是否执行下一相位的指令,当前相位的绿灯执行时间大于最小绿灯时间,当前相位的车流量为零,下一相位的车流量大于零时或者当前相位的绿灯执行时间等于绿灯的最大时间时,控制信号灯执行下一相位的指令。本发明提出的一种交通信号灯动态配时方法及装置解决了交通信号灯资源的浪费,减少了交通信号灯的空放时间,有效的提高了路口的通行效率。
