  • Why Does the "hourvmtfraction" Table in the MOVES Default Database Include Fractions for roadTypeID 1 (off-network)?

    See More Frequent Questions about MOVES and Related Models . The original concept for MOVES assumed that there would be some vehicle miles traveled (VMT) not accounted for in the other four road types. This remaining VMT would be accounted for in roadTypeID=1. As the model developed, it was decided…

  • How Can I Incorporate Local Data Into My MOVES-Nonroad Run?

    See More Frequent Questions about MOVES and Related Models . We recommend not modifying the internal tables of the MOVES-Nonroad model to incorporate local data, as this can lead to unintended consequences. Instead, you can apply local activity and population data by: Executing a nonroad run in Inventory mode for…

  • Can I model emissions from Electric, Fuel-Cell, and Hybrid Vehicles and Equipment in MOVES?

    See More Frequent Questions about MOVES and Related Models . Electric vehicles and equipment do not generate tailpipe or evaporative emissions like conventional vehicles. However, these vehicles do consume energy, leading to greenhouse gas emissions, and they generate brake and tire particulate matter (PM) emissions. MOVES includes electricity as a…

  • Is MOVES the best tool for my work?

    See More Frequent Questions about MOVES and Related Models . EPA’s MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for U.S. mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics. States other than California must…
