In order to evaluate our predictions of emissions, we plan to use MOVES by Environmental Protection Agency (EPA), that estimates emissions for mobile sources.\cite{epa} It does so by taking various inputs which are as follows:
· Scale: In this we need to select whether the model is Onroad or NonRoad. Then we need to select which database we want to use. There is a default national database which has some default state and allocation factor. Then we need to select the calculation type whether it is emissions for a region or emissions per unit activity.
· Time span: This includes selection of different aggregation levels of time by year, month and day of week (weekdays or weekends or both).
· Geographic bounds: Here we need to specify whether analysis at what level – nation, state, country, zone, etc.
· Vehicle equipment: This requires user to select combinations of fuels (like diesel, CNG) and source types (like Passenger car, Motorcycle).
· Road Types: There are bunch of options here like urban, rural, etc.
· Pollutants and processes: Here we need to select the pollutants for which emissions are calculated along with processes (like Brakewear, start exhaust)
· Input Database: We can either use the default database or we can create our own. MOVES uses MYSQL database.
· Output: We need to select units for output. Also location for storing results needs to be specified.
After the model is run, the output can be viewed in a summary report. We will use this report as a reference to compare our results. Following figures show MOVES output for a test run on their inbuilt database.
