The embodiment of the invention discloses a traffic signal control method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining the state information of a current stage of a current intersection; receiving a control action of the previous stage of the adjacent intersection of the current intersection; determining an average value of the codesof the control actions of the previous stage close to the intersection; and determining the control action of the current stage of the current intersection based on the state information of the current stage of the current intersection and the average value of the codes of the control action of the previous stage of the adjacent intersection, thereby taking the interaction between all intelligentagents and the traffic flow environment as a random game problem. The dimension of an action space is reduced through average field approximation, the interaction problem of the intelligent agent andother intelligent agents is converted into the interaction problem of a certain average effect of the intelligent agent and an adjacent intelligent agent, and the problem of dimension disasters is avoided.

    本公开实施例公开了一种交通信号控制方法、装置、电子设备及可读存储介质,其中,该方法包括获取当前路口的当前阶段的状态信息;接收所述当前路口的临近路口的前一阶段的控制动作;确定所述临近路口的前一阶段的控制动作的编码的平均值;基于所述当前路口的当前阶段的状态信息和所述临近路口的前一阶段的控制动作的编码的平均值,确定所述当前路口的当前阶段的控制动作,从而将全体智能体与交通流量环境的交互作为一个随机博弈问题,通过平均场近似来减小动作空间的维度,将本智能体与其他智能体的交互问题转化为本智能体与临近智能体的某种平均效应的交互问题,避免了“维度灾难”问题。
