MOVES (Motor Vehicle Emission Simulator) - Frequent Questions
How can I reduce the long time needed to run the Nonroad emission factor post-processing scripts?
Can N2O (nitrous oxide) emissions be estimated in the MOVES Nonroad model?
How do I get carbon dioxide equivalent (CO2e) results for Nonroad equipment?
Does MOVES2010a incorporate anticipated improvements in VOC emission factors resulting from improved fuel economy?
Using MOVES2010, I am unable to generate VOC emissions using my runspec with the newly updated MOVES default database (MOVESDB20100515). If I change the MOVES configuration setting to point to the old MOVES database (MOVESDB20091221), then VOC emissions a
What is the difference between extended idling and normal idling? Is it possible to get distinct idling emission output for any vehicle type? Can this be done in the emission rate mode, or only inventory mode?
When I use the 20100515 default database with MOVES2010, the evaporative components for methane (CH4) don't show up on the Pollutants and Processes panel. They do when I switch back to the 20091221 database. How do I get methane for the evaporative proces

What does MOVES assume for future year fleet fuel efficiency?
Why doesn't my output VMT match my input VMT?
Why in my nonroad results do I have a fuelTypeID not listed in the FuelType table?
How do I get emission factors or inventory totals for Nonroad equipment aggregated by the various categories used by MOVES?
How can I be sure MOVES is providing the information I asked for? For example, when I do a run for just source/fuel type diesel ? refuse truck and look at the MOVES execution table for that run, I can see that in addition to refuse trucks, activity was ge
How can I get MOVES to indicate what emission processes and fueltypes I am modeling? For example, when I do a run for just source/fuel type diesel ? refuse truck; the output does not differentiate emissions by processID or sourceType.
How do I output the population of each of the 13 MOVES sourcetypes sub-classified based on the fuel type?

How can I calculate the emission rates for a particular speed (e.g. 28.3mph) when using the "Emission Rates" in MOVES. The emission rate output is provided by speed bin.
How can I determine the impact of speed on vehicle emissions?
