MOVES (MOtor Vehicle Emissions Simulator) is a computer program designed by the US Environmental Protection Agency (EPA) to estimate air pollution emissions from on-road mobile sources. EPA created MOVES as a state-of-the-art model for estimating emissions from all on-road vehicles including cars, trucks, motorcycles, and buses. MOVES can be used to estimate exhaust and evaporative emissions as well as brake and tire wear emissions from all types of on-road vehicles for any part of the country, except California. Officially released in 2010, the MOVES model version MOVES2010 officially replaced the previous on-road emissions model, MOBILE6.2. Subsequently, EPA has made minor revisions to this version in releases of MOVES2010a and MOVES2010b.
- MOVES2010a Regional Level Sensitivity Analysis (December 2012) – Prepared by Volpe National Transportation Systems Center for FHWA, this document discusses the sensitivity of various input parameter effects on emission rates using MOVES2010a at the regional level. Pollutants included in the study are CO, NOx, PM2.5, and VOCs.
- Modifying Link-Level Emissions Modeling Procedures for Applications within the MOVES Framework (September 2010) - Prepared by Eastern Research Group, Inc. for FHWA, the primary goal of the study was to ease the transition to the MOVES model by providing both a road map for developing updated emissions inventories, as well as an analysis of the likely impacts of the transition on the emissions inventories themselves.

Policy & Guidance
- MOVES2010b Questions and Answers (PDF) (April 2012) - This document highlights the differences between MOVES2010b and earlier versions of MOVES and explains EPA policy on using MOVES2010b in State Implementation Plans and Transportation Conformity Analyses.
- Policy Guidance on the Use of MOVES2010 and Subsequent Minor Revisions for State Implementation Plan Development, Transportation Conformity, and Other Purposes (PDF) (April 2012) - This document describes how and when to use the MOVES2010 (and subsequent minor revisions like MOVES2010b) for SIP development, transportation conformity, general conformity, and other purposes.
- Using MOVES to Prepare Emission Inventories in State Implementation Plans and Transportation Conformity: Technical Guidance for MOVES2010, 2010a and 2010b (PDF) (April 2012) - This document provides guidance on appropriate input assumptions and sources of data for the use of MOVES2010, MOVES2010a, and MOVES2010b in SIP submissions and regional emissions analyses for transportation conformity purposes.
- Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas (EPA, December 2010) - Guidance for modeling the local air quality impacts of certain transportation projects on the PM2.5 and PM10 national ambient air quality standards (NAAQS). This guidance is to be used by state and local agencies to conduct quantitative PM “hot-spot analyses” for new highway and transit projects that involve significant diesel emissions.

Fact Sheet (HTML) or (PDF)
- Using MOVES in Project-Level Carbon Monoxide Analyses (EPA, December 2010) - This guidance describes how to use the MOVES emissions model to estimate CO emissions from transportation projects, including roadway intersections, highways, transit projects, parking lots and intermodal terminals.
- Federal Register Notice of Availability: Official Release of the MOVES2010a and EMFAC2007 Motor Vehicle Emissions Models for Transportation Conformity Hot-Spot Analyses and Availability of Modeling Guidance (December 2010) – This notice approves MOVES2010a for PM and CO hot-spot analyses (and EMFAC2007 for PM hot-spot analyses in California) with a 2-year conformity grace period. EPA also announced the availability of its final PM hot-spot guidance and CO project-level MOVES guidance.
- MOVES2010 Mobile Source Emissions Model: Questions and Answers (PDF) (December 2009) - This document describes the model and provides general information for model use.
- Federal Register Notice of Availability: Official Release of MOVES2010 Motor Vehicle Emissions Model for Emissions Inventories in SIPs and Transportation Conformity (March 2010) - This notice approves the use of MOVES2010 in official SIP submissions and starts a two-year grace period before MOVES2010 is required to be used in new regional emissions analyses for transportation conformity determinations outside of California.
- EPA/FHWA MOVES Training - EPA and FHWA will be offering MOVES training in a number of different formats. Course descriptions and availability are listed on EPA's website.
- EPA/DOT Training for Quantitative PM Hot-Spot Analyses - EPA and DOT have developed a three-day training course on implementing EPA's "Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas. This technical, hands-on course is geared toward state and local agency staff and will focus on using emission models (including EPA's MOVES model) and air quality models (AERMOD and CAL3QHCR) for quantitative PM hot-spot analyses.
