Technical Field

The invention relates to the field of traffic road facilities, in particular to an inclination early warning method and an inclination early warning system for a road sign.

Background

In recent years, the operating mileage and traffic flow of the expressway in China are continuously increased, and a large number of signs are arranged at high speed and used for indicating various driving information such as direction, speed and the like and putting some advertisements. These signs may be due to years of maintenance, subsidence of the foundation, lack of location, typhoons, earthquakes, and the like. Resulting in a physical tilt of the sign.

At high speed, when the sign board declines, if the degree is serious, and the height of the passing vehicle is higher, such as a truck, an off-road vehicle and the like, the passing height allowance of the vehicle is insufficient, and severe traffic accidents are easy to happen; particularly, when the vehicle passes at night or in foggy days, a driver cannot timely perceive the vehicle, and when the vehicle is found to be in a state, the vehicle is braked within insufficient time, and finally the vehicle collides with the indicating board, so that traffic accidents are caused, normal traffic operation is influenced, and certain economic loss is brought. How to find the sign slope in the very first time to the sign slope information is sent to the vehicle of passing by, tells the maximum height data that the vehicle allows to pass, makes things convenient for the driver to judge the risk in advance and handles in advance, has become the technical problem that needs the solution.
