Abstract

The invention discloses a traffic discharge pollution visualization early warning method, which includes the basic data information of the monitoring area; extracts the characteristics of the relative position information; selects the optimal air quality monitoring station and the optimal traffic road node; constructs the prediction of air pollutants model; build a pollutant concentration prediction model for any monitoring point and correct it; perform visual early warning of urban traffic pollution emissions in the monitoring area. The invention also discloses a system for realizing the traffic discharge pollution visualization early warning method. The method of the invention can perform real-time prediction and early warning of real-time dynamic air pollutants at any point in the road traffic coverage area, and the method of the invention has high reliability and good practicability.

Description

technical field [0001] The invention specifically relates to a visual early warning method and system for traffic discharge pollution. Background technique [0002] In recent years, with the deepening of industrialization and urbanization and the increasing popularity of private cars, the problem of air pollution in my country has become increasingly serious. The air quality is deteriorating day by day, which has an important impact on the health of urban residents and the economic development of society. With the increasing popularity of intelligent algorithms such as machine learning and deep neural networks, the use of intelligent algorithms to predict air pollutants based on environmental big data has great potential in assisting relevant departments in decision-making, improving environmental protection efficiency, controlling the spread of pollutants, and realizing industrial regulation. important value. In the area covered by urban roads, exhaust emissions during ve...
