Abstract

On-road vehicle traffic is one of the largest sources of hazardous air pollutant emissions in the United States (U.S.) and underserved communities are consistently found to bear a disproportionate share of exposure to on-road vehicle traffic emissions. In this study, we present an updated analysis of the U.S. near-roadway population using traffic data from 2018 and 2020 census data, refined equity analysis methods, and new emission density exposure surrogates. Results suggest that people of color and those with low incomes are disproportionately exposed to higher levels of air pollutants along roadways in the U.S
