The invention discloses a traffic conflict identification method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring vehicle trajectory data of a level crossing of a target city in a preset time period, and road basic data of the level crossing; determining the speed, course angle and course of each vehicle according to the vehicle trajectory data and the road basic data; wherein the course angle is an included angle between the head direction of the vehicle and a preset direction; determining whether a traffic conflict occurs between the first vehicle and the second vehicle by using a preset conflict identification model based on the heading of the first vehicle and the second vehicle; wherein the first vehicle and the second vehicle are different vehicles in the vehicle trajectory data; and if yes, determining the time, the position and the conflict type of the traffic conflict between the first vehicle and the second vehicle. According to the invention, a technical problem that traffic conflict identification cannot be carried out between vehicles at a lane-level urban intersection in the prior art is solved.

    本发明公开了一种交通冲突识别方法、装置、存储介质及电子设备。其中,上述方法包括:获取预设时间段内目标城市的平交路口的车辆轨迹数据,以及所述平交路口的道路基础数据;根据所述车辆轨迹数据和所述道路基础数据确定每个车辆的速度、航向角和航向;其中,所述航向角为车辆的车头方向与预设方向之间的夹角;基于第一车辆和第二车辆的航向利用预设的冲突识别模型确定所述第一车辆和第二车辆是否发生交通冲突;其中,所述第一车辆和第二车辆为所述车辆轨迹数据中不同的车辆;若是,则确定所述第一车辆和第二车辆发生交通冲突的时间、位置和冲突类型。本发明解决了相关技术中无法对车道级的城市路口车辆之间进行交通冲突识别的技术问题。
