Modelling Urban Traffic Air Pollution Dispersion
The prime aim of this research is to support decision making, e.g., air quality impact analysis, human health assessment, through spatially modelling traffic-induced air pollution dispersion in urban areas at street level. Based on the information needed in decision making, a framework for a street level air quality decision support system is established, which is composed of basically three pa...
متن کاملAnalysis of air quality data near roadways using a dispersion model
We used a dispersion model to analyze measurements made during a field study conducted by the U.S. EPA in July–August 2006, to estimate the impact of traffic emissions on air quality at distances of tens of meters from an eight-lane highway located in Raleigh, NC. The air quality measurements consisted of long path optical measurements of NO at distances of 7 and 17m from the edge of the highwa...
متن کاملAssessment of Air Quality Trends Near Roadways
Executive Summary: In this project our group set out to determine what effect, if any, an air monitor's distance from the roadway had on the measured air pollution levels of carbon monoxide, nitrogen dioxide, and fine particulate matter (PM2.5). The group was also searching to see if we could identify pollution emitters using wind data. "Fine particles," such as those found in smoke and haze, a...
متن کاملProximity Plus Pollution: Understanding Factors in Asthma among Children Living near Major Roadways
Compact urban development would reduce urban sprawl, leading to shorter driving distances and ultimately less regional air pollution. But it would also mean greater housing density in a given area, potentially increasing the number of residences near major roadways. Given that exposure to traffic emissions near roadways is strongly associated with asthma and related symptoms in children, a new ...
متن کاملResolving local-scale emissions for modeling air quality near roadways.
A large body of literature published in recent years suggests increased health risk due to exposure of people to air pollution in close proximity to roadways. As a result, there is a need to more accurately represent the spatial concentration gradients near roadways to develop mitigation strategies. In this paper, we present a practical, readily adaptable methodology, using a "bottom-up" approa...
