A National Assessment of the Air Quality and Health Impacts of Vehicle Travel and Electrification: Phase 1 Near Roadway Impacts and Equity Analysis

Principal Investigator Gregory Rowangould, Ph.D.
University of Vermont

This project will address limitations in the current literature surrounding air quality impacts of vehicle traffic, especially in underserved communities. The team will employ a refined near-roadway emission exposure surrogate that balances spatial precision and computational burden to estimate changes in exposure levels and health risks and the distribution of these burdens over time as EV adoption increases.
