The invention discloses a complex underground road driving safety risk road vehicle targeted early warning method comprising the following steps: carrying out identification and trajectory tracking on a vehicle to obtain a vehicle identification tracking result; based on the vehicle identification tracking result, determining the traffic safety field intensity at the target point in the road space; and if the field intensity of the traffic safety field at the target point exceeds a set threshold value, taking the vehicle closest to the target point as a risk vehicle, and sending early warning information to the risk vehicle. According to the invention, the driving safety risk of the vehicle on the road section can be comprehensively sensed, and the early warning information is accurately pushed to the risk vehicle, so that the operation safety level of the complex underground road and the three-dimensional traffic is improved.
本发明公开了一种复杂地下道路行驶安全风险路车靶向预警方法,包括:对车辆进行识别与轨迹跟踪,得到车辆识别跟踪结果;基于车辆识别跟踪结果,确定道路空间内目标点处的行车安全场场强;若目标点处的行车安全场场强的大小超过设定阈值,则将与目标点距离最近的车辆作为风险车辆,并向风险车辆发送预警信息。本发明能够全面感知路段上车辆的行驶安全风险,准确推送预警信息至风险车辆,从而提升了复杂地下道路及所在立体交通的运行安全水平。
