Title: Geofencing as a Strategy to Lower Emissions in Disadvantaged Communities

Principal Investigator / Author(s): Boriboonsomsin, Kanok

Contractor: UC Riverside

Contract Number: 17RD009


Research Program Area: Atmospheric Processes, Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels, Toxic Air Contaminants, Vulnerable Populations


Research Summary:

Previous in-house ARB research comparing the trends in traffic-related pollutant concentrations in high and low socioeconomic status communities has shown that while ambient fine particles (PM2.5) concentrations are decreasing everywhere, higher concentrations are still found in the most disadvantaged communities (DACs). Geofencing is a promising new strategy to reduce such exposures. Geofencing allows a user to define virtual spatial boundaries on top of a real-world view of a specific geographical area within which a pollution emitter, such as heavy-duty vehicles, could be triggered to employ methods to reduce emission. This project aims to identify and evaluate geofencing strategies in the heavy-duty sector that could lower emissions in DACs or other areas of poor air quality, either all the time or during specific time periods. The researchers will model emission reductions associated with the implementation of geofencing strategies in the selected study areas, relative to a baseline scenario. The results from this research will provide important information that could be used to inform the development of geofencing technologies, as well as the development of incentive or regulatory policies by ARB, that reduce pollutant emissions in DACs.
