Urban road traffic pollutant emission monitoring system

Abstract

The invention provides an urban road traffic pollutant emission monitoring system. The system comprises a data collection subsystem, a data analysis subsystem and an information publishing device, wherein the data collection subsystem is used for collecting and processing traffic pollutant emission data on each traffic road and corresponding traffic flow, road alignment and weather information; the analysis module is used for analyzing the data sent by the data collection subsystem, quantitatively and qualitatively analyzing the influence mechanism of traffic flow, road alignment and weather on traffic pollutant emission, mining the inner link between the traffic flow, road alignment and weather and traffic pollutant emission and outputting an analysis result of the inner link; and the information publishing device is used for displaying the analysis result.

Description

technical field [0001] The invention relates to the technical field of pollution monitoring, in particular to an urban road traffic pollutant discharge monitoring system. Background technique [0002] Exhaust emissions from motor vehicles are closely related to traffic flow behavior. Frequent acceleration and deceleration of vehicles in the process of going straight, changing lanes, overtaking, and turning will lead to increased pollution emissions. Existing research has not yet systematically and quantitatively revealed the impact of traffic flow behavior on it. , most studies focus on the qualitative analysis of the importance of fuel consumption, road types, start-up braking, signal control, speed control, one-way traffic, and bus priority to traffic pollutant gas emissions from a macro perspective. Only a few studies analyze traffic flow behavior and pollutant gases However, it does not involve the internal and external micro-factors of traffic such as road alignment des...

[0002] Exhaust emissions from motor vehicles are closely related to traffic flow behavior. Frequent acceleration and deceleration of vehicles in the process of going straight, changing lanes, overtaking, and turning will lead to increased pollution emissions. Existing research has not yet systematically and quantitatively revealed the impact of traffic flow behavior on it. , most studies focus on the qualitative analysis of the importance of fuel consumption, road types, start-up braking, signal control, speed control, one-way traffic, and bus priority to traffic pollutant gas emissions from a macro perspective. Only a few studies analyze traffic flow behavior and pollutant gases However, it does not involve the internal and external micro-factors of traffic such as road alignment design and weather changes, which affect traffic flow behavior, and then they affect the emission level of traffic pollutant gases, which will inevitably lead to one-sided or erroneous part of the existing research theory
