A road ultrasonic vehicle positioning and risk early warning system comprises an ultrasonic positioning and early warning all-in-one machine and an edge base station. The ultrasonic positioning and early warning all-in-one machines are arranged and installed on a road side guardrail or a stand column at intervals, and the edge base station is arranged and installed in a road side derrick case or cabinet and connected with the multiple ultrasonic positioning and early warning all-in-one machines. According to the road ultrasonic vehicle positioning and risk early warning method, a corresponding risk early warning scheme is automatically generated according to vehicle information and traffic state information, and acousto-optic early warning information is issued to guide a driver to drive safely. The method is easy to deploy and install, low in construction cost and beneficial to improvement of road traffic safety and traffic efficiency; compared with other traffic state monitoring equipment, the detection precision is high, the detection range is wide, the microscopic driving track and data of the vehicle can be obtained, and the event identification and risk prediction accuracy is high; compared with other early warning issuing equipment, the device has the advantages of automatic control, dynamic issuing of acousto-optic signals, strong warning effect and good information continuity.
公路超声波车辆定位及风险预警系统,包括超声波定位预警一体机和边缘基站;所述超声波定位预警一体机间隔部署安装在公路路侧护栏或立柱上,所述边缘基站部署安装在公路路侧抱杆机箱或机柜中,边缘基站连接多个超声波定位预警一体机。公路超声波车辆定位及风险预警方法,根据车辆信息和交通状态信息,自动生成相应的风险预警方案并发布声光预警信息引导驾驶员安全驾驶。本发明部署安装简单,施工成本低,并且有利于改善道路交通安全和通行效率;与其他交通状态监测设备比,检测精度高,检测范围广,可以获取车辆微观行驶轨迹和数据,事件识别和风险预测准确性高;与其他预警发布设备比,自动控制、动态发布声光信号,警示效果强,信息连续性好。
