Effectiveness of vegetation and sound wall-vegetation combination barriers on pollution dispersion from freeways under early morning conditions
Pollutants in tailpipe emissions can be highly elevated around roadways, and in early
mornings the pollution plume can extend hundreds of meters into surrounding
neighborhoods. Solid sound walls and vegetation barriers are commonly used to mitigate
noise, but they also help mitigate near-road air pollution. Here we assess the effectiveness
of barriers consisting of vegetation only and of a combination of vegetation and a solid
sound wall (combination barrier) in reducing pollution concentrations downwind of roads …
