Mountainous area expressway snowfall environment early warning system and method

Abstract

The invention discloses a mountainous area expressway snowfall environment early warning system. The system is formed by the following function systems of an information monitoring and collection system, an information processing system, a decision support system, an information release system, and an evaluation system which are connected to a communication system. A meteorological information monitoring and collecting sensor, a pavement condition information monitoring and collecting sensor, and a traffic flow detecting sensor are integrated into one body and are arranged in the unfavorable section of a mountainous area expressway so that a defect that a current highway meteorological monitoring station does not adapt to road area environment uniqueness, suddenness and regional performance is effectively overcome. Meteorological information, pavement condition information, and traffic flow information data are collected in real time and data support is provided for the 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 relatively optimal safety management countermeasures, and transmits to the site for release through the information release system. The safe and high-efficiency operation of a vehicle under a snowfallenvironment is finally realized.

Description

technical field [0001] The invention relates to the technical field of expressway pavement condition early warning, in particular to a snowfall environment early warning system and method for expressway in mountainous areas. Background technique [0002] The emergence of sudden severe weather has caused extensive impact on transportation. Severe weather conditions, especially snowfall, 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 fundamentally different from the severe weather monitoring in the road environment, which is reflected in the following aspects: [0004] (1) Differ...
