Mountain highway rainfall environment early warning system and method

Abstract

The invention discloses a mountain highway rainfall environment early warning system. The system is formed by an information monitoring and acquisition system, an information processing system, a decision support system, an information release system and an evaluation system which are connected to a communication system. In the invention, a meteorological information monitoring and acquisition sensor, a road condition information monitoring and acquisition sensor, and a traffic flow detection sensor are integrated into one body and are arranged in the typical section position of a highway in amountain area. The defects of current highway meteorological monitoring station and road domain environment differences, burstiness and area disharmony are effectively overcome. Meteorological information, road surface condition information, and traffic flow information data are collected in real time and data support is provided for an information processing system. According to the analysis result of the information processing system, the decision support system considers safety, a traffic level and an economic index, comprehensively determines a relatively optimal safety management countermeasure, and transmits to the site for releasing through the information release system. The safe and high-efficient operation of a pavement under a rainfall environment is finally realized.

Description

technical field [0001] The invention relates to the technical field of early warning of road conditions of expressways in mountainous areas, in particular to an early warning system and method for rainfall environment of expressways in mountainous areas. Background technique [0002] With the change of global climate conditions, sudden severe weather occurs frequently, resulting in the influence of weather conditions on transportation is becoming more and more extensive. Severe weather conditions, including heavy rainfall, have brought huge losses and hidden dangers to road transportation and safety. Timely and accurate acquisition of meteorological information, road surface information, and traffic information in the road area environment is crucial to determine effective control measures. [0003] At present, although the monitoring stations of the meteorological department are relatively complete, they are not suitable for the needs of traffic services, and are fundament...
