Tools for MOVES (Motor Vehicle Emission Simulator)

The following tools are designed to help users develop inputs to MOVES and post-process the output.

Tools to develop special case MOVES inputs

LEV and early NLEV modeling information (ZIP) (4.78MB) (Updated August 2010) Some states have adopted California Low Emission Vehicle (LEV) standards.  Other states (in the northeast) that did not adopt LEV standards received early implementation of National Low Emission Vehicle (NLEV) standards for the 1999 and 2000 model years.  This package includes instructions and input files that can be used with MOVES2010 and MOVES2010a to model the emissions from these vehicles.

Retrofit Converter (Excel) (1.1MB) (Updated March 2012) The On-Road Retrofit strategy panel (described in Section 2.9.9 and Appendix D of the MOVES User Guide) allows the user to enter information about diesel trucks and buses that have installed additional emission control equipment. See EPA’s Verification program for more information about the percent efficiency of verified devices. This user-friendly file includes instructions and input files that can be used with MOVES2010, MOVES2010a and MOVES2010b to model emissions from these vehicles with retrofits. It automatically converts Diesel Emissions Quantifier and MOBILE6 vehicle categories into MOVES formats.

Tools to convert MOBILE6 inputs to MOVES formats

The following spreadsheet tools help simplify the transition from MOBILE6.2 to MOVES by taking MOBILE (or NMIM) formatted input files and converting them to MOVES format. Each spreadsheet includes detailed instructions with a more complete description of the capabilities of the spreadsheet.

NOTE: You will need Adobe Acrobat Reader, available as a free download, to view some of the files on this page. See EPA's PDF page to learn more about PDF, and for a link to the free Acrobat Reader.

Average Speed Converter MOBILE6 (XLS) (9.3MB)
This Excel file converts a MOBILE6-formatted speed distribution file to the format needed by the MOVES AvgSpeedDistribution table. The file also expands the MOBILE6 speed bin 14 to MOVES speed bins 14, 15, and 16 and converts the data from VMT-based speed bins to time-based speed bins.

Average Speed Converter NMIM (XLS) (14.3MB)
This Excel file takes all 18 NMIM-formatted speed distribution files and converts them to the format needed by the MOVES AvgSpeedDistribution table. The file also expands NMIM's speed vehicle bin 14 to MOVES speed bins 14 to 16.

RegistrationDistributionConverter_Veh16 (XLS) (5.37MB) (Rev. 02/2010)
This Excel file takes a MOBILE6-formatted registration distribution file and converts it to the format needed by the MOVES SourceTypeAgeDistribution table.

Meteorological Data Converter MOBILE6 (XLS) (393K)
This Excel file converts MOBILE6-formatted meteorological data (temperature and humidity) to the format needed by the MOVES County Data Manager to populate the ZoneMonthHour table.

Meteorological Data Converter NMIM (XLS) (229K)
This Excel file converts NMIM-formatted meteorological data (temperature and relative humidity) from the NMIM CountyYearMonthHour table to the format needed by the MOVES County Data Manager to populate the ZoneMonthHour table.

VMT Converters:

There are 8 VMT converter files that can be separated into two groups. Set 1 (those with "RoadVMT" in the title) allows the user to enter total VMT data for each HPMS road type and assign vehicle type fractions to allocate VMT on the road type; Set 2 requires the user enter the specific VMT of a vehicle type on a road type. All the files convert VMT data based on MOBILE6 or NMIM vehicle types and road types to MOVES vehicle (source) types and road types. In addition, they:

  • convert hourly VMT allocation factor data to the format needed by the MOVES HourVMTFraction table;
  • calculate distributions of VMT by road type for each MOVES source type for the MOVES RoadTypeDistribution table;
  • calculate fractions of VMT occurring on ramps for the MOVES restricted access road types to populate the MOVES RoadType table; and
  • convert the registration distribution data to the format needed by the MOVES SourceTypeAgeDistribution table (except for the Veh28 converters).

Tools to post-process output for project-level analyses

EPA has developed several scripts to automate the process of calculating MOVES emission factors for use in air quality modeling. Each script automates the post-processing steps described in Sections 4.4.7 and 4.6 of the EPA guidance document: Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas (EPA-420-B-10-040, December 2010) and Sections 2.3.7 and 2.5 of the EPA guidance document: Using MOVES in Project-Level Carbon Monoxide Analyses (PDF) (59 pp, 2M, EPA420-B-10-041, December 2010).

These scripts were previously available on this website for use in MOVES2010a. However, since the scripts have been added to the post-processing menu of MOVES2010b, they were removed from this website. Agencies using MOVES2010a may request the scripts by emailing mobile@epa.gov.

Tool to generate EMISFACT portion of an AERMOD input file

EPA has developed a tool to automate the process of generating the EMISFACT portion of an AERMOD input file using MOVES output. The tool is intended to be used as part of a quantitative PM hot-spot analysis, as described in EPA’s “Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas.” MOVES2AERMOD can be run directly through the MOVES GUI. Included in the download package are several necessary files:

  • readme.txt – Describes how to “install” the tool as well as providing instructions on using it for PM hot-spot analyses
  • MOVES2AERMOD input data
    • Link_Sources.csv – Define a mapping of MOVES links to AERMOD sources
    • Source_Area.csv – Define the area of each MOVES link
    • Traffic_Distribution – Define the peak/off-peak mapping for each of 24 hours, and four seasons
  • MOVES2AERMOD.sql – This file should be placed in the appropriate MOVES folder as described in the readme.txt file
  • Transit_exercise_out – An example database containing output from 16 MOVES runs used to test the MOVES2AERMOD tool

Download the tool: MOVES2AERMOD (ZIP) (1.78MB, October 2012)

Questions about downloading or using MOVES2AERMOD for PM hot-spot analyses should be emailed to Dresser.Chris@epa.gov.
