The invention discloses a highway in-transit vehicle operation risk early warning method and system based on vehicle-infrastructure cooperation. The method comprises the steps that a road section where a vehicle is located is recognized in real time; whether the driving speed of the vehicle is smaller than the speed limit value of the road section is judged, and if yes, early warning is not carried out; and if not, a set early warning mode is selected to carry out early warning reminding on the vehicle. According to the invention, real-time updating of road section state information data can be avoided, and vehicle operation risk early warning of any road section at any time is realized.

    本发明公开了一种基于车路协同的公路在途车辆运行风险预警方法及系统,包括:实时识别车辆所处的路段;判断车辆的行驶速度是否小于所处路段的限速值,若是,则不进行预警;若否,则选择设定的预警方式对车辆进行预警提醒。本发明能够避免路段状态信息数据需要实时更新,实现了任何路段、任何时间的车辆运行风险预警。
