The invention provides a traffic signal lamp state prediction method and device, equipment and a storage medium, and relates to the technical field of traffic data processing, and the method comprises the steps: obtaining a first historical video of an entrance direction of a preset traffic intersection in a first historical time period before the current time, and carrying out the prediction of a traffic signal lamp state according to the first historical video; generating a first historical vehicle tracking trajectory in the entrance direction, determining a first historical vehicle state of the target lane corresponding to the entrance direction from the first historical vehicle tracking trajectory and a first historical vehicle motion trajectory from the entrance direction to the corresponding exit direction, and determining a target lane according to the first historical vehicle motion trajectory and the first historical vehicle state. And predicting the current state information of the preset traffic signal lamp at the current time by adopting a pre-constructed state model of the preset traffic signal lamp in the entrance direction. By optimizing the state model of the preset traffic signal lamp, the predicted current state information of the preset traffic signal lamp at the current time is more accurate.

    本申请提供了一种交通信号灯状态预测方法、装置、设备及存储介质,涉及交通数据处理技术领域,该方法包括:获取预设交通路口在当前时间之前的第一历史时间段的进口方向的第一历史视频,根据第一历史视频,生成进口方向的第一历史车辆跟踪轨迹,从第一历史车辆跟踪轨迹中确定进口方向对应目标车道的第一历史车辆状态,以及从进口方向至对应出口方向的第一历史车辆运动轨迹,根据第一历史车辆运动轨迹以及第一历史车辆状态,采用预先构建的进口方向的预设交通信号灯的状态模型,预测预设交通信号灯在当前时间的当前状态信息。通过对预设交通信号灯的状态模型的优化,使得预测出预设交通信号灯在当前时间的当前状态信息更加准确。
