The invention relates to the technical field of equipment control, and provides a traffic signal lamp control method and device, terminal equipment and a storage medium. The method comprises the following steps: acquiring driving state data of each vehicle at a traffic intersection, wherein the driving state data comprises a future driving direction of the corresponding vehicle at the traffic intersection; inputting the driving state data into a trained signal lamp control model for processing, and controlling a signal lamp at a traffic intersection through a state action value function output by the signal lamp control model; wherein the signal lamp control model is a graph neural network obtained through training based on a deep reinforcement learning algorithm, nodes of the graph neural network are phases of signal lamps, and feature data of the nodes are driving state data of vehicles of all passable lanes under the corresponding phases; the state of the deep reinforcement learning algorithm is driving state data of the vehicle, and the action is each phase of the signal lamp. The method can improve the timing accuracy of the signal lamp, thereby improving the vehicle passing efficiency.

    本申请涉及设备控制技术领域,提出一种交通信号灯的控制方法、装置、终端设备和存储介质。该方法包括:获取交通路口中每个车辆的行驶状态数据,行驶状态数据包括对应车辆在交通路口的未来行驶方向;将行驶状态数据输入至已训练的信号灯控制模型进行处理,通过信号灯控制模型输出的状态动作价值函数,对交通路口的信号灯进行控制;其中,信号灯控制模型为基于深度强化学习算法训练得到的图神经网络,图神经网络的节点为信号灯的各个相位,各个节点的特征数据为对应相位下所有可通行车道的车辆的行驶状态数据,深度强化学习算法的状态为车辆的行驶状态数据,动作为信号灯的各个相位。采用该方法能够提高信号灯配时的准确度,从而提升车辆通行效率。
