2.16.2.1. MOVES Driver Script

The inputs to the MOVES Driver Script (Runspec_generator.pl) include the temperature and humidity conditions output from Met4moves and two additional inputs, the RunControl and RepCounty files. The RunControl file contains pollutant selections and the file path location to the Met4moves output. The RepCounty file contains file path locations to user-created MOVES-formatted inputs for age distribution, fuel supply and formulation, inspection and maintenance programs, county level population and annual VMT for each representative county. Precise formats of the RunControl and RepCounty files can be found in the Section 8.9.2.2.2, “Representative County File for MOVES Driver Script” and Section 8.9.2.2.1, “Run Control File for MOVES Driver Script”.

2.16.2.2. MOVES Post-processing Script

A MOVES Driver Script to automates the MOVES run setups and prepare two kinds of batch files. When launched, the batch files instruct MOVES to:

  • import data into MySQL County Scale databases

  • run MOVES for each runspec file

The resulting RatePerDistance (RPD), RatePerVehicle (RPV), RatePerProfile (RPP), and RatePerHour (RPH) tables contain all the conditions needed for regional modeling using SMOKE modeling system.

Once a MOVES batch run completes, MOVES populates the four output lookup tables with formats listed in Table 2.10, “MOVES Emission Rate Lookup Table (MOVES Format)”. A MOVES Post-processing Script (Moves2smkEF.pl) in Perl interacts with MySQL to modify the default formats shown in Table 2.10, “MOVES Emission Rate Lookup Table (MOVES Format)” into a text ASCII-format readable by SMOKE, shown in Table 2.11, “MOVES Emission Rate Lookup Table (SMOKE Format)”.

The MOVES Post-processing Script converts the MOVES format Emission Rate Lookup Table to the SMOKE format Emission Rate Table by performing the following:

  • Parses the state-county FIPS code from linkID, zoneID or TemperatureProfileID and stores it as a unique field, FIPS.

  • Removes fields that are uninformative to SMOKE, including the MOVES source type, fuel type and road type, hourID in RatePerDistance, TemperatureProfileID in RatePerProfile.

  • Reduces the output database table size by performing a cross-tab query on the pollutant emissions, listing each pollutant in a separate field rather than in a single column with a higher number of data records. The script also sorts the lookup tables by countyID, monthID and SCC for more efficient processing in SMOKE.

  • Optionally calculates additional output pollutants or species by applying user-specified formulas to MOVES-created emission factors.

  • Write out to the ASCII-formatted four processed SMOKE-ready MOVES lookup tables [RatePerDistance (RPD), RatePerVehicle (RPV), RatePerProfile (RPP), and RatePerHour (RPH)].
