The invention discloses a method for detecting traffic flow anomalies. The method comprises the following steps: acquiring three-dimensional geographic position information data of all vehicles on a monitoring route; dividing the monitoring route into a plurality of monitoring road sections, and determining the normal vehicle capacity of each monitoring road section; according to the three-dimensional geographic position information data of all the vehicles, the actual vehicle number of the current monitored road section is counted, and the actual vehicle number of the current monitored road section is compared with the normal vehicle capacity; wherein if the actual vehicle number of the current monitoring road section is larger than the normal vehicle capacity of the current monitoring road section, it is judged that the traffic flow of the current monitoring road section is abnormal. According to the method for detecting the traffic flow anomaly, the three-dimensional geographic position of the vehicle can be accurately determined, and the number of vehicles on the monitored road section is determined according to the three-dimensional geographic position information of the vehicle, so that the accuracy of a traffic flow anomaly detection result is improved.

    本发明公开了一种检测交通流量异常的方法,包括:获取监测路线上的所有车辆的三维地理位置信息数据;将所述监测路线划分为多个监测路段,并且确定每个监测路段的正常车辆容载量;根据所有车辆的三维地理位置信息数据,统计当前监测路段的实际车辆数,并将当前监测路段的实际车辆数与正常车辆容载量进行对比;其中,如果当前监测路段的实际车辆数大于当前监测路段的正常车辆容载量,则判断当前监测路段交通流量异常。本发明提供的检测交通流量异常的方法,能够准确的确定车辆所处的三维地理位置,并且根据车辆所处的三维地理位置信息确定监测路段上的车辆数,从而提高交通流量异常检测结果的准确性。
