The invention provides a method and device for determining an abnormal road section of a road area and a storage medium. The method for determining the abnormal road section of the road area comprisesthe steps of acquiring trajectory data of a plurality of historical orders, and determining yaw information of the plurality of historical orders according to the trajectory data; according to the trajectory data and the yaw information, obtaining a plurality of target starting and ending points in the road area and trajectory mode information of each target starting and ending point; and determining an abnormal road section of the road area according to the track mode information. The technical scheme of the invention is different from a road network anomaly detection method for excavating road network anomalies through a statistical model and the like by taking road section flow as an index in related technologies. According to the technical scheme, the problems of yaw information, complexity of road network space, uneven road section heat distribution and the like are considered, the abnormity is positioned through the track mode information of the multiple target starting and ending points, the situation that the abnormity of the road section is judged only through the flow of the single road section is avoided, and the accuracy of road section abnormity positioning is improved.

    本发明提出了一种道路区域的异常路段确定方法、装置及存储介质。其中,道路区域的异常路段确定方法包括:获取多个历史订单的轨迹数据,根据轨迹数据确定多个历史订单的偏航信息;根据轨迹数据和偏航信息,获取道路区域内的多个目标起止点以及每个目标起止点的轨迹模式信息;根据轨迹模式信息,确定道路区域的异常路段。本发明的技术方案不同于相关技术中以路段流量作为指标通过统计模型等挖掘路网异常的路网异常检测方法,本发明的技术方案考虑了偏航信息、路网空间的复杂性及路段热度分布不均匀等问题,通过多个目标起止点的轨迹模式信息定位异常,避免仅由单个路段的流程判断该路段的异常情况,提高了路段异常定位的精确性。
