How do I Obtain the Populations for Each of the MOVES Source Types?
To output vehicle populations, when setting up your RunSpec select the "Inventory" calculation type from the Scale panel and the "Population" activity option from the General Output panel of the MOVES GUI.
The movesactivityoutput table in your MOVES output database will contain population data at the level of detail selected in the Output Emission Detail panel (fuel type, model year, etc.).
