The invention discloses a road high-precision positioning system and method, and the system comprises a vehicle position collection module which is used for collecting the vehicle position information on a road; the road shape collection module is used for collecting road shape information; the road surface early warning module is used for acquiring a parameter value of a corresponding road, comparing the parameter value with a corresponding threshold value and generating lamp display state information; the data transmission module is used for transmitting the lamp display state information, the vehicle position information and the road shape information to the central control module; and the central control module is used for generating a control instruction based on the vehicle position information, the road shape information and the lamp display state information, and regulating and controlling the lamp display state of each road surface early warning module based on the control instruction. When sudden surface water and liquid accumulation, icing, accident fire disasters and road surface collapse deformation occur on a road, the system can timely send out remote display early warning to a driving vehicle, so that larger accidents are avoided, and the purpose of assisting safe driving is achieved.

    本发明公开了一种道路高精度定位系统和方法,包括:车辆位置收集模块,用于收集道路上的车辆位置信息;道路形状收集模块,用于收集道路形状信息;路面预警模块,用于获取对应道路的参数值,并将参数值与对应的阈值进行比较,并生成灯显状态信息;数据传输模块,用于将灯显状态信息、车辆位置信息、道路形状信息传输至中央控制模块;中央控制模块,用于基于车辆位置信息、道路形状信息、灯显状态信息生成控制指令,并基于控制指令调控各个路面预警模块的灯显状态。在道路出现突发性地面积水积液、结冰、事故火灾及路面坍塌形变时,本发明能够对行驶车辆及时发出远方显示预警,避免引发更大的事故,达到辅助安全行车的目的。
