Who could benefit from this research

Could help

Ideal participants are DC residents, especially those in neighborhoods with high traffic emissions and asthma or air pollution concerns.

Less likely to help

Individuals not directly affected by traffic-related air pollution or without asthma may see less direct benefit.

What this research studies

This project looks at how road pricing could influence traffic, air pollution, and health in DC. Researchers will combine neighborhood input with data on NO2 and PM2.5 to understand potential benefits and unintended effects outside the pricing area. The work uses big data approaches to map emissions and health impacts and to inform policy decisions that could affect daily commuting and access to transportation. Results could guide city leaders in designing road pricing that improves air quality while minimizing harms to vulnerable communities.

Why it matters

Potential benefit: If successful, the study could help implement road pricing in a way that improves air quality and reduces asthma-related burdens for DC residents.

How similar studies have gone: Policy-focused air quality studies have shown that targeted interventions can affect emissions and health, though effects may vary by location.
