Project Brief / Introduction:

Traditional monitoring systems (i.e., fixed-site air quality stations) or satellite-based estimates are insufficient to capture the microenvironmental and temporal variability of individual pollution exposure. Wearable air pollution sensors, combined with GPS-enabled mobility tracking, offer a promising approach to measure real-time personal exposure in real-world environments.

This pilot study among XanhSM scooter delivery drivers will generate practical and technical evidence to support larger population-based studies in Vietnam. It will also provide baseline evidence for future evaluations of transportation electrification policies. Beginning in 2026, Hanoi will implement a district-by-district ban on gas-powered motorcycles, starting within Ring Road 1, creating a timely opportunity to assess the health impacts of transport electrification in a low- and middle-income country context.

Findings from this study will inform the design of longitudinal studies before and after the ban, the assessment of socioeconomic and equity implications for vulnerable populations, and future evaluations of similar policies, including potential bans on gas-powered cars in Hanoi and Ho Chi Minh City.
