Background on MOVES3

MOVES3 is now the latest official version of MOVES and has been updated and improved from the previous version by:

  • Incorporating the latest data on vehicle populations, travel activity, and emission rates as well as updated fuel supply information at the county level.
  • Adjusting modeling to better account for vehicle starts, long-haul truck hotelling, and off-network idling.
  • Incorporating the impacts of the Heavy-Duty Greenhouse Gas Phase 2 rule and the Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule.
  • Improving the user interface to make the model easier to use and updating the platform for compatibility with newer software.

These updates ensure that MOVES3 is a state-of the-science model to estimate motor vehicle emissions and the most accurate tool for estimating emissions from the transportation sector for most purposes.
