The invention discloses a road intersection vehicle conflict prediction method, device and equipment and a storage medium, and the method comprises the steps: obtaining a vehicle at a road intersection, and taking the vehicle as a target vehicle; predicting a driving track of the target vehicle to obtain a predicted driving track; generating a dynamic interaction frame of each target vehicle based on the predicted driving track; and predicting the vehicle conflict based on the dynamic interaction frame. By means of the method, an original rectangular frame is changed into a curve frame based on the predicted trajectory through a trajectory prediction method, complex steering behaviors during vehicle driving can be better described, and the expected driving behaviors of the vehicle can be considered so that potential conflict objects can be recognized in advance. And meanwhile, aiming at the interaction condition of the road intersection, a conflict identification method is predicted from space and time, so that the accuracy of predicting the vehicle conflict is ensured while the calculated amount is reduced.
本发明公开了一种道路交叉口的车辆冲突预测方法、装置、设备及存储介质,该方法包括:获取处于道路交叉口的车辆,作为目标车辆;对所述目标车辆的行驶轨迹进行预测,获得预测行驶轨迹;基于所述预测行驶轨迹生成各所述目标车辆的动态交互框;基于所述动态交互框对车辆冲突进行预测。利用该方法,通过轨迹预测方法,将原始长方形框改为基于预测轨迹的曲线框,既能够更好描述车辆行驶时的复杂转向行为,又能够考虑到车辆的预期驾驶行为以提前辨识潜在冲突对象。同时针对道路交叉口的交互情况,从空间和时间预测冲突的辨识方法,减少计算量的同时保证了预测车辆冲突的准确性。
