non-tailpipe emissions

Building on their previous research on environmental life cycle assessment (LCA) for heavy-duty trucks, the researchers will conduct a social LCA analysis to assess the social impacts of battery-electric and fuel cell trucks.

In this study, the researchers will measure the gaseous emissions from the off-gassing of tires during laboratory and real-world testing conditions. The researchers will also evaluate the secondary organic aerosol forming potential from the off-gassing of tires during only laboratory conditions using state-of-the-art instrumentation.

In this study, the research team will: 1) measure real-world brake activities of a large volume of vehicles traversing major roadway segments (e.g., near signalized intersections) by leveraging advanced roadside sensing technologies, e.g., Light Detection and Ranging and/or high-definition camera, as well as deep learning-based computer vision algorithms; and 2) construct the real-world brake activity database and supplement for the non-tailpipe emissions inventory.
