The invention discloses a vehicle running road risk early warning method, device and equipment and a storage medium. The method comprises the steps of obtaining historical track sequences of all traffic objects in a target road section collected by a road side unit, inputting the historical track sequences of all the traffic objects into a preset interaction feature extraction model for processing to obtain interaction features representing interaction information between the traffic objects, and for each traffic object in the target road section, extracting the interaction information between the traffic objects; the behavior of the traffic object at the next moment is predicted based on the historical track sequence of the traffic object, the interaction characteristics and the map information of the target road section, and when the traffic object has an abnormal behavior, an early warning signal is sent to a target vehicle in a lane influenced by the abnormal behavior in the communication range of the road side unit through the road side unit. The behavior of the traffic object in the target road section can be predicted in advance, abnormal behavior early warning is given out in advance, sufficient processing time is provided for the target vehicle, and the road traffic safety is improved.

    本发明公开了一种车辆运行道路风险预警方法、装置、设备及存储介质。方法包括:获取路侧单元采集的目标路段内所有交通对象的历史轨迹序列,将所有交通对象的历史轨迹序列输入预设的交互特征提取模型中进行处理,得到表征交通对象间交互信息的交互特征,针对目标路段内的每一交通对象,基于交通对象的历史轨迹序列、交互特征和目标路段的地图信息,预测交通对象在下一时刻的行为,在交通对象出现异常行为时,通过路侧单元向路侧单元通讯范围内受异常行为影响的车道内的目标车辆发送预警信号,能够提前预测目标路段内交通对象的行为,并提前发出异常行为预警,给目标车辆充足的处理时间,提高道路交通安全性。
