Intelligent site selection system for highway meteorological observation station under complex terrain and application method

Abstract

The invention discloses an intelligent site selection system for a highway meteorological observation station under complex terrain. An analysis platform comprises a user interaction unit, a data acquisition unit, a road meteorological disaster risk assessment model unit, a space analysis unit and a big data calculation and site selection model unit. An artificial intelligence analysis technologyis used as a tool; natural attributes such as long downhill, curvature, tunnel, bridge and the like of the road are comprehensively considered. Meanwhile, meteorological disaster risks of heavy rainfall, low visibility, strong wind, freezing rain and snow and the like and actual road disasters and hidden danger factors such as road traffic accidents, agglomerate fog-prone sections and accumulatedsnow-prone sections are also considered; under the combined action of related software, scientific site selection of the meteorological observation station can be carried out through a spatial data platform and an artificial intelligence algorithm provided based on a GIS, the obtained construction site selection of the road meteorological observation station is more standard and effective, and therefore powerful scientific and technical support is provided for highway meteorological observation station network construction in China in future. Based on the method, the method has a good prospect.

Description

technical field [0001] The invention relates to the field of data analysis systems and analysis methods, in particular to an intelligent site selection system and application method for expressway meteorological observation stations under complex terrain. Background technique [0002] As of the end of 2016, my country's expressway mileage has exceeded 130,000 kilometers, ranking first in the world in total. Nearly 40% of my country's goods are transferred through expressways. In 2015, the total number of traffic accidents in my country was 187,781, the number of accident deaths was 58,022, and the property loss was 1,036.92 million yuan. Among them, there were 21,215 traffic accidents under adverse weather conditions such as rain, snow, and fog, and the number of accident deaths reached 7,159. According to statistics from the Traffic Safety Research Center of the Ministry of Public Security, more than 22% of accidents are caused by bad weather. Meteorological disasters and ...

Problems solved by technology

How to select the site of the road meteorological observation station is a necessary condition to ensure that the road meteorological observation station can play its due function after construction. Although the layout principle of the national expressway traffic meteorological observation station network has been issued, the specific location is still unclear. There is no relevant technology and method, so it will cause certain restrictions on the construction of road weather observation stations

[0003] At present, although a certain number of highway traffic meteorological observation stations have been built, which can provide a certain example for the subsequent construction of road meteorological observation stations, the data of the existing observation stations are not representative, and the observation elements are mainly conventional meteorology. Observation capabilities for elements such as visibility and road conditions that are concerned with traffic safety are obviously insufficient. Therefore, it affects the benefits of professional meteorological services for road traffic.
