The invention discloses an expressway vehicle space-time path prediction method and device, and relates to the technical field of traffic information, and the method comprises the steps: determining a to-be-predicted target expressway section, carrying out the expressway section division of the target expressway section, and obtaining a sub expressway section set; acquiring sub-passing duration when all target vehicles pass through each sub-expressway section, and calculating sub-comprehensive passing duration of each sub-expressway section; and determining an abnormal sub-expressway section based on the sub-comprehensive passing duration, further determining an abnormal influence factor of the abnormal sub-expressway section, and performing vehicle space-time path prediction based on the abnormal influence factor. Therefore, by implementing the method, the determination accuracy of the abnormal sub-expressway section set can be improved, the determination accuracy of the abnormal influence factors of the abnormal sub-expressway sections is further improved, and thus the accuracy and stability of expressway vehicle space-time path prediction are improved.

    本发明公开了一种高速公路车辆时空路径预测方法及装置,涉及交通信息技术领域,该方法包括:确定待预测的目标高速路段并对目标高速路段进行高速路段划分,得到子高速路段集合;获取所有目标车辆在通过每个子高速路段时的子通过时长并计算每个子高速路段的子综合通过时长;基于子综合通过时长确定异常子高速路段并进一步确定该异常子高速路段的异常影响因子,基于异常影响因子执行车辆时空路径预测。可见,实施本发明能够提高异常子高速路段集合的确定准确性,进而提高异常子高速路段的异常影响因子的确定准确性,从而提高高速公路车辆时空路径预测的准确性和稳定性。
