A kind of early warning system and method for icing environment of mountain expressway

Abstract

The invention discloses an early warning system for icing environment on a mountainous expressway, which is composed of the following functional systems connected by a communication system, an information monitoring and acquisition system, an information processing system, a decision support system, an information release system and an evaluation system. Meteorological information monitoring and acquisition sensors, road surface condition information monitoring and acquisition sensors, and traffic flow detection sensors are integrated and arranged in the most unfavorable low-temperature environment section of mountainous expressways, which effectively overcomes the differences, suddenness and Regional incompatibility defects. Collect meteorological information, road condition information and traffic flow information data in real time to provide data support for the information processing system. Based on the analysis results of the information processing system, the decision support system comprehensively determines the relatively optimal safety management countermeasures based on the analysis results of the information processing system, taking into account safety, traffic level and economic indicators, and transmits them to the site through the information release system for release, finally realizing safe and efficient operation on icy roads .

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...
