Development of Inputs, Outputs, and Procedures
for EPAs Draft MOVES2009 Model

• Sunil Kumar and Eulalie Lucas
• MOVES Task Force Meeting
• MWCOG
• August 18, 2009

2

• MOVES Model Introduction
• MOVES - Motor Vehicle Emission Simulator
• MOVES - a complete emissions estimation package.
  Produces total emissions.
• Mobile6.2 - only emissions factors, which were
  processed outside the model to calculate total
  emissions.
• MOVES Extensive set of input files produces
  emissions at three (3) different levels
  National, County/Regional and Project
• MOVES Input files Importers, Revised
  processes from Mobile6.2, Totally new features.

• MOVES Local Data Needs
• Required Local Datasets
• Fuel Characteristics
• Meteorology
• I/M Program
• Age Distribution (Registration data)
• Population of MOVES Vehicle Types
• (for each county or region in a calendar year)
• Total Base Year VMT for HPMS Vehicle Types
• (for each county or region in a calendar year)
• VMT Fraction across MOVES Road Types for each
  MOVES Vehicle Types

• Required Local Data Sets Status
• 1. Fuel Characteristics
• Local data available. Appropriate fuel
  formulation can be identified from the list
  provided with the MOVES model.
• 2. Meteorology
• Local data available. Needs minimal formatting
  for MOVES application.
• 3. I/M Program
• Local data available. Needs minimal formatting
  for MOVES application.
• 4. Age Distribution (Registration data)
• Local data available.
• Two options for MOVES application
• A. Use EPA tool to convert existing age
  distribution data available by Mobile6 vehicle
  types (1-25 years old) into MOVES vehicle types
  (0-30 years old).
• B. Develop age distribution data by MOVES vehicle
  types (0-30 years old).

Annual VMT by HPMS Vehicle Types (MOVES Allocation)
Motorcycle
Passenger Car
Other 2 axle-4 tire vehicles
Bus
Single Unit Trucks
Combination Trucks
Development of annual VMT use NEI method or HPMS
approach?

7. VMT Fraction Local data

• VMT fraction - input data format for Mob6
  MOVES are very different
• Mob6 COG/DTP VMT fractions
• Distributed across 16 Mob6 vehicle types 1 set
  each for Network, Local roads, and Auto access to
  transit facilities (Total 3 sets of VMT
  fractions)
  (DTP VMT fraction
  Mob6 VMT fraction modified with local truck
  fraction)
• MOVES VMT fractions
• Distributed across 4 MOVES road types
  (Urban/rural restricted/unrestricted)
• 1 set each for 13 individual MOVES vehicle types
  (Total 13 sets of VMT fractions)
• Development of MOVES VMT fractions
• Use NEI method ?
• HPMS approach?

Summary Needs Status of Local Data
MOVES Inputs Status of Local Data
Fuel Characteristics Local data available. Appropriate fuel formulation can be identified from the list provided with the MOVES model.
I/M Programs Local data available. Needs formatting for MOVES.
Meteorology Data Local data available.
Age Distribution Mobile6 based local data conversion to MOVES format possible. Direct local data development in MOVES format preferred by EPA.
Vehicle Type Population Vehicle population data available by Mob6 vehicle types can be converted to MOVES types using EPA provided conversion formula (EPA formula based on national level data).
Vehicle Type VMT Local data available by FHWA facility types. Need annual VMT by HPMS vehicle types. Needs to be developed (using NEI assumption ?).
VMT Fraction VMT fractions across FHWA facility types available. Need VMT fraction across MOVES road types for each MOVES vehicle types. Needs to be developed (using NEI assumptions ?).
Ramp Fraction Local data available.
Speed Distribution Local data not available.
