Near-Road Air Quality: Insights from a U.S. DOT Five-Year Transportation Pooled Fund Study
Research shows that substantial traffic, especially diesel-powered trucks and buses, can create pollution hot spots within a few hundred meters of major roads. In recognition of the importance of addressing near-road air pollution, eight state and federal agencies pooled their research efforts on the topic, obtaining and evaluating an unprecedented amount of near-road air quality data.
