Heavy-Duty Vehicle Activity for EPA MOVES
The U.S. Environmental Protection Agency?s (EPA?s) MOtor Vehicle Emission Simulator (MOVES) is a publicly available tool used by researchers and policymakers to help understand motor vehicle emission sources at a national, county, and project level. Estimates of heavy-duty activity in the previous version of the model were identified as an area in need of improvement. As a joint effort, EPA and NREL have cooperated to analyze the start and idle activity of heavy-duty vehicles using two on-road datasets: 1. Fleet DNA database from NREL and 2. CE-CERT data collected by the University of California, Riverside for the California Air Resources Board. The combined dataset includes 564 commercial vehicles and more than 23,000 vehicle days? operation and covers seven of nine heavy-duty vehicle source types defined by the MOVES. In this dataset, the detailed analytical results, as well as the corresponding metadata information, were stored to be publicly available.
