Problems solved by technology

[0003] Existing traffic pollution health risk assessment methods are usually based on coarse-grained traffic activity data, and the accuracy of the assessment results is low. Population is another key input variable for pollutant health risk assessment, and the health risks of different groups of people are quite different. , the existing health risk assessment methods cannot distinguish the characteristics of the population, and cannot achieve refined health risk assessment

Abstract

The invention provides a traffic pollution health risk assessment method and system. The method comprises the following steps: acquiring driving data and meteorological data of a research area; calculating the pollutant emission intensity of each road segment according to the driving data; dividing the research area into a plurality of sub-areas; calculating the pollutant concentration of each sub-region according to the meteorological data and the pollutant emission intensity of the road segment; classifying the crowds in the research area based on age and / or gender; acquiring risk parameters of each type of people, wherein the risk parameters are used for representing influence differences of pollutant concentrations on different types of people; and evaluating the health risk of each type of people based on the pollutant concentration and the risk parameter of each sub-region. According to the method, high-resolution pollutant emission intensity and risk parameters of differentiation of different crowds are taken as input, so that the health risk assessment precision is improved.

Description

technical field [0001] This application relates to the technical field of environmental health, in particular to a method and system for assessing traffic pollution health risks. Background technique [0002] Traffic emissions are an important urban problem facing the world and an important source of urban pollution. In recent years, China's ground transportation has developed rapidly, and the number of motor vehicles has increased sharply. The air pollution caused by this emission is serious, and the PM produced 2.5 Seriously endanger human health. Given PM 2.5 As a serious threat to human health, it is the research focus of those skilled in the art to assess the health risks caused by traffic pollution. [0003] Existing traffic pollution health risk assessment methods are usually based on coarse-grained traffic activity data, and the accuracy of the assessment results is low. Population is another key input variable for pollutant health risk assessment, and the health ...
