Why Does the "hourvmtfraction" Table in the MOVES Default Database Include Fractions for roadTypeID 1 (off-network)?
See More Frequent Questions about MOVES and Related Models . The original concept for MOVES assumed that there would be some vehicle miles traveled (VMT) not accounted for in the other four road types. This remaining VMT would be accounted for in roadTypeID=1. As the model developed, it was decided…

How can I Install the NONROAD Model?
See More Frequent Questions about MOVES and Related Models . EPA no longer supports the stand-alone FORTRAN version of the NONROAD model. It likely would need to be recompiled for use in current versions of the Windows operating system. Instead, EPA has included Nonroad equipment estimates in our current MOVES…

When I Click on Produce Summary Report Following an Emission Rates Run, Why Do I Get An Error Message that says "Database Error Occurred Trying to Produce Report Header Table"?
See More Frequent Questions about MOVES and Related Models . The Summary Reporter does not work when you choose the Emission Rate calculation in the Scale panel. It only works with the Inventory calculation selection. The emission rates that you generated are found in the RatePerDistance, RatePerProfile and RatePerVehicle tables…

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?
See More Frequent Questions about MOVES and Related Models . Extended idling is a distinct emission process defined as the overnight idling of long-haul trucks with sleeper cabs at truck stops and other locations during federally required downtime. During such idling periods, these engines experience unusual loads (televisions, air conditioning…

What Drives Seasonal CO Emission Trends?
See More Frequent Questions about MOVES and Related Models . Once a vehicle’s engine/catalyst reaches operating temperature, the ambient temperature has little effect on the emissions performance of the vehicle. These “running” emission rates in MOVES have no temperature adjustment. However, during summer months at warm temperatures, MOVES assumes extensive…
