MOVES4 Update Log

This page provides a chronological listing of updates to MOVES4.

See the MOVES5 Update Log for the latest versions of MOVES.

On this page:

• MOVES4.0.2
• MOVES4.0.1
• MOVES4.0.0
• Prior versions of MOVES

In general, modelers should use EPA’s latest model, MOVES5, to take advantage of its improved capabilities and updated default values.

Users should consult the Federal Register Notice of Availability for MOVES5 and the MOVES5 Policy Guidance (both available on the MOVES latest version page) before doing any additional work with any prior version of MOVES.

Modelers continuing to use MOVES4 may use any version below. MOVES4.0.2 is more recent and incorporates the changes made in MOVES4.0.0 and MOVES4.0.1.

All versions of MOVES4 are available for download at the MOVES GitHub Releases page. Additional information on MOVES4 is available on the MOVES Versions in Limited Current Use page.

MOVES4.0.2

MOVES4.0.2 is a patch to MOVES4. It does not substantially change onroad criteria pollutant emission rates in MOVES4 at the County or Project Scales, and it is not considered a new model for state implementation plan or transportation conformity regulatory purposes.

Compared to MOVES4.0.1, emissions from MOVES4.0.2 may differ, especially if the modeler is modeling a large fraction of CNG long-haul trucks, providing start activity input for only one day type, or providing HotellingHoursPerDay input for less than 12 months.

MOVES4.0.2 includes the following updates to MOVES4.0.1:

• We repaired problems including:
  • missing PM emissions for CNG long-haul combination trucks
  • an issue when aggregating over dayID when using the summary reporter
  • a problem when importing user-supplied start activity input for only one day type
  • an issue with hotelling emissions when running on Linux
  • a problem when importing user-supplied HotellingHoursPerDay for less than all 12 months
  • an error in summary reporter when selecting certain pollutants
  • an error in the Nonroad NEI QA script
• We improved Project Scale error checking for LinkIDs less than one.
• We added the MOVES version number to window titles in the graphical interface.
• We included improvements to Project Scale runtime made for MOVES5
• We upgraded ANT to version 1.10.15

For additional technical details on these changes, see the MOVES4.0.2 milestone on the MOVES GitHub site.

MOVES4.0.1

MOVES4.0.1 is a patch to MOVES4. It does not substantially change onroad criteria pollutant emission rates in MOVES4 at the County or Project scales, and it is not considered a new model for State Implementation Plan and transportation conformity regulatory purposes. Compared to MOVES4.0.0, MOVES4.0.1 will produce slightly different results when temporal pre-aggregation is selected in County Scale runs where passenger cars are not selected. (Note, pre-aggregation cannot be used for SIP or transportation conformity purposes.)

MOVES4.0.1 includes the following updates:

• We made it possible to input local vehicle population and vehicle miles travelled when using the Default Scale.
• We added a new nonroad post-processing script that generates gram per hour emission factors by source classification code and model year.
• We added a button to open the AVFT Tool from within the County Database Manager “Fuel” tab.
• We improved the documentation and functionality of the script that checks MOVES submissions for use in the National Emission Inventory (NEI).
• We added a check to most user inputs that flags importing “null” values as an error.
• We added two new command line tools currently in beta development:
  • The “MOVES Output Grouper,” which can be useful when running MOVES in a parallel computing environment. For background and information on how to use the tool, see tool’s documentation on GitHub.
  • The “Operating Mode Distribution Calculator,” which replicates MOVES default scale VMT and SHO calculations but saves the results at a greater level of detail, including by average speed bin and operating mode. For background and information on how to use the tool, see the tool's documentation on GitHub.
• In addition, we repaired minor errors:
  • We fixed two errors in the onroad speciation profile post-processing scripts.
  • We resolved a problem with temporal pre-aggregation at County Scale in runs that did not include passenger cars. (Note, pre-aggregation cannot be used for SIP or transportation conformity purposes.)
  • We resolved an error that prevented running multiple counties at Default Scale.
  • We removed an irrelevant error message at Project Scale.

For additional technical details on these changes, see the MOVES4.0.1 milestone on the MOVES GitHub site.
