The invention provides a pedestrian clearing time calculation method based on trajectory prediction. The pedestrian clearing time calculation method comprises the steps of obtaining trajectory data of a last pedestrian entering an intersection when green flashing of a signal lamp at a preset intersection in a preset time period starts; performing conversion and standardization processing on the pedestrian trajectory data according to a preset coordinate system to obtain a pedestrian trajectory sequence; inputting the pedestrian trajectory sequence into a preset trajectory prediction model to obtain pedestrian prediction trajectory data; the preset trajectory prediction model is obtained by taking historical pedestrian trajectory data of the preset intersection as a training sample and performing training through an LSTM neural network; and obtaining predicted pedestrian clearing time according to the pedestrian prediction trajectory data. The pedestrian clearing time is set in a more scientific mode, the street crossing requirement of pedestrians is met, and pedestrian safety is guaranteed.

    本发明提供了一种基于轨迹预测的行人清空时间计算方法,包括:获取预设时间段内预设路口处的信号灯绿闪开始时最后一个进入交叉口的行人轨迹数据;对所述行人轨迹数据按照预设坐标系进行转换和标准化处理,得到行人轨迹序列;将所述行人轨迹序列输入到预设轨迹预测模型中,得到行人预测轨迹数据;所述预设轨迹预测模型是以所述预设路口的历史行人轨迹数据为训练样本,并通过LSTM神经网络进行训练得到的;根据所述行人预测轨迹数据得到预测行人清空时间。本发明用更科学的方式设置行人清空时间,满足行人过街需求,保障行人安全。
