The invention provides an intelligent signal lamp timing optimization method, device, equipment and system, and a medium. The method comprises the steps: obtaining real-time traffic flow information of an intersection; calculating the queue length of vehicles waiting for passing corresponding to each phase according to the real-time traffic flow information; inputting the length of the vehicle queue waiting for passing corresponding to each phase into a fuzzy controller to obtain the street lamp duration required by each phase, and selecting the phase corresponding to the longest street lamp duration as the next phase; performing reinforcement learning according to the next phase to adjust the time amount of the street lamp duration required by each phase, and outputting a signal lamp instruction to the signal lamp of the intersection according to the time amount. According to the invention, real-time signal lamp timing optimization can be carried out on a single crossroad, so the traffic jam in an urban road traffic peak period is effectively relieved, the red light waiting time of vehicles in a road traffic low peak period is reduced, the signal lamps are more intelligent, and the flexibility is better.
本申请提供的一种智能信号灯配时优化方法、装置、设备、系统和介质,通过获取一路口的实时车流信息;依据实时车流信息计算各相位对应等待通行的车辆队列长度;将各相位对应等待通行的所述车辆队列长度输入模糊控制器得到各相位所需的路灯时长,并将最长的路灯时长所对应的相位选择为下一相位;依据下一相位进行强化学习以调整各相位所需的路灯时长的时间量,并据以向该路口的信号灯输出信号灯指令。本申请能对单个十字路口进行实时的信号灯配时优化,进而有效缓解城市道路通行高峰期的交通拥堵,减少道路通行低峰期车辆的红灯等待时间,使信号灯更加智能化,具有更好的灵活性。
