The invention provides a method, system and device for predicting the vehicle queuing length of an intersection and a storage medium, and the method comprises the steps: obtaining the historical vehicle queuing length of each direction, and training a traffic prediction model according to the historical vehicle traffic; and counting the saturation flow rate of the target direction in the current period, and predicting the queuing length of the target direction in the next period according to the training flow prediction model, the saturation flow rate and the historical vehicle queuing length. According to the method, the real-time positions of all vehicles are obtained through the roadside sensing equipment, the queuing length at the intersection is calculated in real time, and the vehicle queuing length in the target direction is predicted according to the historical vehicle flow.

    本发明提供一种预测交叉路口车辆排队长度的方法、系统、设备和存储介质,方法包括:获取每个方向的历史车辆排队长度,并根据历史车辆流量训练流量预测模型;统计当前周期目标方向的饱和流率,并根据所述训练流量预测模型、所述饱和流率和所述历史车辆排队长度预测下一个周期所述目标方向的排队长度。本发明通过路侧感知设备获取全量车辆的实时位置,实时计算交叉口排队长度,并根据历史车辆流量预测目标方向的车辆排队长度。
