The invention provides a road traffic early warning device, and relates to the technical field of traffic safety. The road traffic early warning device comprises an expressway, a first portal frame, a second portal frame and a third portal frame, according to the system, the speed of a rear vehicle is detected through the first tachymeter, when the speed of the rear vehicle is too high, the central processing unit judges the lane where the vehicle is located according to the first tachymeter, the central processing unit enables the displayer to display the license plate number of the corresponding vehicle, and the warning lamp flickers to remind the passing vehicle; the second tachymeter detects the speed of the rear vehicle and firstly judges whether the rear vehicle slows down or not, if the rear vehicle does not slows down or slows down insufficiently, the Beidou satellite module positions the position of the vehicle in real time, meanwhile, the GPS module judges whether navigation of the vehicle is turned on or not, and if the navigation system is in the turned-on state, the navigation prompt module prompts the running vehicle to slow down again. And early warning can be given to road traffic.
本发明提供一种道路交通预警装置,涉及交通安全技术领域。该道路交通预警装置,包括高速道路以及高速道路上安装的一号龙门架、二号龙门架与三号龙门架。本发明,通过一号测速仪检测后车的车速,当后车车速过快时,中央处理器首先根据一号测速仪判断车辆所处于的车道,中央处理器使得显示器显示对应车辆的车牌号,警报灯出现闪烁提醒经过车辆,在后车行驶过二号龙门架时,二号测速仪对后车车速进行检测,首先判断后车是否减速,如果后车仍没有减速或者降速不够,北斗卫星模块实时定位该车辆的位置,同时GPS模块判断该车辆导航是否打开,若导航系统处于打开状态,导航提示模块提示行驶车辆再次减速,能够给道路交通作出预警。
