Data from: Understanding real-world brake activity: A key to assessing non-tailpipe emission sources for sustainable transportation and communities

Electrification is considered a promising solution to environmental
sustainability, due to the removal of tailpipe emissions (during
operation) from the transportation sector. However, this would
not have too much effect on those non-tailpipe particulate emissions. In
addition, brake and tire wear particles are composed of various
metals, rubber compounds, and organics which includes adhesives
and have potential higher risks on the community health effects. In this
study, the research team proposes to: 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. It is expected that this study will
contribute to the improvement of non-tailpipe emissions modeling and
understanding. The findings from this study will help address the
environmental justice issues in disadvantaged communities.
