Description:
A growing number of epidemiological studies conducted throughout the world have identified an increase in occurrence of adverse health effects for populations residing, working or attending school near major roadways. In addition, several air quality studies have identified increased concentration levels of certain pollutants near high traffic volume roads. The U.S. EPA has begun a research program investigating the relationship of traffic activity, environmental conditions, and near road air quality. This paper investigates the influence of noise barriers, vegetation and other roadside structures on air pollutant configurations near the road.
