Modeling and Inventories
MOVES (Motor Vehicle Emission Simulator)
EPA's Office of Transportation and Air Quality (OTAQ) has developed the MOtor Vehicle Emission Simulator (MOVES). This emission modeling system estimates emissions for mobile sources covering a broad range of pollutants and allows multiple scale analysis.
MOVES2014. MOVES2014 is the latest version of MOVES and includes the benefits of the Tier 3 rule as well the impacts of other EPA rulemakings promulgated since the last MOVES release, new emissions data, and new features that users have requested. MOVES2014 also includes the NONROAD2008 model, allowing for modeling of both on-road and nonroad mobile sources within the MOVES platform.
Please find the latest guidance on Using MOVES for State Implementation Plans (SIP) and Transportation Conformity here:
