The invention relates to a traffic conflict prediction method and device, computer equipment and a storage medium, and the method comprises the steps: collecting the driving sequence information of a to-be-detected vehicle through a road side sensor, and determining the to-be-detected vehicle is located in an intersection region according to the map information corresponding to the intersection; obtaining central point distances of at least two to-be-measured vehicles in the corresponding intersection area, and for each central point distance, fitting according to the driving sequence information to obtain a predicted driving track of each to-be-measured vehicle corresponding to the central point distance when the central point distance is greater than a corresponding distance threshold value; according to the prediction driving track corresponding to each central point distance, the traffic conflict in the intersection area is predicted, high-risk interaction events possibly occurring in the intersection area can be accurately predicted, early warning is carried out in time, and therefore the safety of road traffic is improved.

    本申请涉及一种交通冲突预测方法、装置、计算机设备和存储介质,通过路侧传感器采集待测车辆的行驶序列信息,在根据交叉口对应的地图信息确定待测车辆处于交叉口区域内的情况下,获取相应交叉口区域内至少两个待测车辆的中心点距离,针对每一中心点距离,在中心点距离大于相应距离阈值的情况下,根据行驶序列信息,拟合得到中心点距离对应的每一待测车辆的预测行驶轨迹,根据每一中心点距离对应的预测行驶轨迹,预测交叉口区域内的交通冲突,能够准确预测交叉口区域内可能发生的高风险交互事件,并及时进行预警,从而提高道路交通的安全性。
