A Modeling Framework for Near-Road Population Exposure to Traffic-Related PM2.5 and Environmental Equity Analysis: A Case Study in Atlanta, Georgia

Research Product Type

Research Report

In this study, a modeling framework for population exposure to traffic-related PM2.5 with high spatiotemporal resolution is proposed and applied to the I-575/I-75 Northwest Corridor (NWC) in Atlanta, GA, for environmental equity analysis.

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.
