Mountain highway icing environment early warning system and method

Abstract

The invention discloses a mountain highway icing environment early warning system. The system is composed of the following functional systems connected to a communication system, namely an informationmonitoring and acquisition system, an information processing system, a decision support system, an information release system and an evaluation system. A meteorological information monitoring and acquisition sensor, a pavement condition information monitoring and acquisition sensor and a traffic flow detection sensor are integrated together, and are arranged in the most unfavorable low temperature environment sections of a mountain highway, so that the defects that an existing highway meteorological monitoring station is not adapted to the road region environment difference, emergency and regionality. Meteorological information, pavement condition information, and traffic flow information data are acquired in real time to provide a data support for the information processing system. The decision support system comprehensively determines a relatively optimal safety management countermeasure by giving consideration to safety, traffic level and economic indicators based on an analysis result of the information processing system, the safety management countermeasure is transmitted to the site for release through the information release system, and finally the safe and efficient operation of icy roads is realized.

Description

technical field [0001] The invention relates to the technical field of expressway pavement condition early warning, in particular to an early warning system and method for icing environment of expressway in mountainous areas. Background technique [0002] After the road surface is covered with ice, the coefficient of friction decreases sharply, and the anti-wet skid performance decreases, which increases the frequency of accidents due to increased braking distance and out-of-control operation of vehicles. Statistics show that 13.5% of fatal accidents and 25% of traffic accidents are caused by poor road surface wet and slippery conditions. In the icy or snowy weather environment, due to the lubricating effect of ice and water, the contact friction between the tire and the road surface is reduced, and the traffic accident rate caused by the decrease in road performance will increase by 25%. Timely and accurate acquisition of meteorological information, road surface informatio...
