Description:
Recent studies have confirmed the increased risks to human health for populations near roadways with large traffic volumes. This paper summarizes methods in which these impacts may be mitigated by infrastructure design options such as roadway configuration and roadside structures (including vegetation) that can offer additional air quality benefits beyond the reduction of direct emissions from motor vehicles. These study results also show that some roadway design features, such as elevated road sections without barriers or vegetation, may lead to increased air pollutant impacts downwind from the road. This paper also provides a summary of potential policy implications and applications for implementing these methods to further protect human health and welfare.
