The Motor Vehicle Emissions Simulator (MOVES) is USEPA’s latest available, state-of-the-art tool for estimating mobile source emissions from highway vehicles. MOVES replaced the MOBILE6 emissions model for use in State Implementation Plans (SIPs) and transportation conformity analyses. It has been used for new SIP development in Georgia since 2010, and for all Atlanta area conformity determinations after a three year grace period ended on March 2, 2013.

The MOVES modeling platform is continually being updated by USEPA. Since its initial release there have been several updates to the software platform. The following documents describe the methodologies used in the Atlanta region to prepare inputs for MOVES-based emissions analyses required under the Clean Air Act as part of transportation conformity in areas not meeting certain air quality standards.

MOVES2010 Methodologies

MOVES2010 was used for conformity determinations beginning with the adoption of the PLAN 2040 Update in March 2014. It was last used for the PLAN 2040 Update Amendment #2 adopted in August 2015.

MOVES2014 Methodologies

MOVES2014 includes more user input options and reflects the latest greenhouse gas and criteria pollutant emission standards. MOVES2014 was used to support The Atlanta Region's Plan, which was adopted in February 2016​.
