The invention provides a traffic abnormal event detection method and device. The method comprises the steps: collecting driving track data of a vehicle in a target tunnel through a plurality of piecesof video detection equipment, and enabling the plurality of pieces of video detection equipment to be arranged at intervals at a preset distance from an entrance to an exit of the target tunnel; determining a lane changing behavior of the vehicle according to the driving track data; generating a lane changing behavior record of the vehicle according to the driving track data and the lane changingbehavior; determining a congestion event and/or an abnormal event in the target tunnel according to the lane change behavior record. According to the invention, problems that in the prior art, traffic events such as serious congestion and traffic abnormality in a tunnel cannot be accurately detected to the lane level, and the detection granularity is not fine enough can be solved; and in a tunnelscene, the traffic event occurring in each lane in the tunnel is detected in real time through the driving track data collected by the multiple video detection equipment on the tunnel.
本发明提供了一种交通异常事件检测方法及装置,其中,该方法包括:通过多个视频检测设备采集目标隧道中车辆的行驶轨迹数据,其中,所述多个视频检测设备从所述目标隧道的入口处至出口处以预定距离间隔设置;根据所述行驶轨迹数据确定所述车辆的变道行为;根据所述行驶轨迹数据与所述变道行为生成所述车辆的变道行为记录;根据所述变道行为记录确定所述目标隧道内的拥堵事件和/或异常事件,可以解决相关技术中对隧道内的严重拥堵、交通异常等,无法精确至车道级别的交通事件检测,检测粒度不够精细的问题,在隧道场景下,通过隧道上多个视频检测设备采集的行驶轨迹数据,实时检测隧道内每个车道发生的交通事件。
