BACKGROUND

This technical report documents how the various input categories needed for successful MOVES model 

runs were developed. It covers the development of both travel-related inputs, which are based on the 

MWCOG/TPB regional travel demand model (Version 2.3. 52), and non-travel related inputs (i.e., 

meteorology, fuel supply and formulation, and Inspection/Maintenance Programs), which were provided by 

agencies from the District of Columbia, the Commonwealth of Virginia, and the state of Maryland. These 

inputs are being provided in Appendix D2 (MOVES2010a county input databases).

INPUT DATA DEVELOPMENT

Input data from ten broad categories were used in the MOVES County Manager in order to generate the 

mobile emissions inventories. The modeling sequence that was followed is graphically illustrated in Figure 

1. 

Figure 1– MOVES Modeling Process

Input data were obtained from a variety of sources (Table 1). Special emphasis was placed on the inclusion 

of local data – where available – instead of MOVES default values, which were derived from national data 

as opposed to regional/local data.

AGE DISTRIBUTION

On a triennial basis since 2005, the Departments of Motor Vehicles (DMV) of the District of Columbia, 

Maryland and Virginia supplied MWCOG/TPB vehicle registration data for use in Air Quality Conformity 

Determinations. These databases contain a broad range of attributes of the vehicles registered in the 

Washington region. 

Prior to being used as inputs in MOVES model runs, the “raw” vehicle registration data – also known as 

Vehicle Identification Numbers (VIN) – were decoded using a commercial decoding software program (1). 

Due to the structure of the decoding software program, the VIN database decoding was achieved in two 

steps: (1) the “raw” data was decoded to a Mobile 6.2-compatible format (vehicle populations distributions 

stratified in 16 vehicle classes and in 25 vehicle age categories); and (2) the Mobile 6.2-compatible vehicle 

population distributions were converted to a MOVES-compatible format (vehicle population distributions 

stratified in 13 vehicle classes and in 31 vehicle age categories) using an EPA-developed converter (2)

while following the process recommended by EPA. The vehicle population mapping process is shown in 

greater detail in Table A1 in the Attachment of this report. 

The vehicle population databases were reviewed by the MWCOG/TPB technical oversight committees and 

went through public comments prior to becoming approved for transportation planning applications. The 

2011 VIN database was formally approved by MWCOG/TPB concurrently with the 2012 CLRP Air Quality 

Conformity Determination (July 2012). Such data was originally provided by the state agencies of the 

District of Columbia, the Commonwealth of Virginia and the state of Maryland in Mobile 6.2-format for use 

in Air Quality Conformity Determination analyses. This data was also converted to MOVES-compatible 

format for inclusion in MOVES model runs. Base year 2011 emissions inventories were based on the 2011 

VIN.

AVERAGE SPEED DISTRIBUTION 

The MWCOG/TPB regional travel demand model derives travel-related outputs – such as VHT -- used for 

Air Quality Conformity by six travel markets:

1. Light Duty Vehicles/Single Occupancy Vehicles (SOV)

2. Light Duty Vehicles/High Occupancy Vehicles (HOV2)

3. Light Duty Vehicles/High Occupancy Vehicles (HOV3+)

4. Airport Passenger Trips

5. Commercial Vehicles

6. Trucks

A custom post processor (i.e., the V2.3 Post Processor) was developed in order to account for Vehicle 

Hours of Travel (VHT) stratified by three major vehicle type categories: passenger vehicles, commercial 

vehicles and heavy duty vehicles. The conversion of the VHT totals by the six travel markets to VHT totals 

by the three major vehicle type categories was done as follows: 

 Passenger Vehicles (PVs) = SOV + HOV2 + HOV3+ + Airport Passenger Trips

 Commercial Vehicles (CVs) = Commercial Vehicles

 Heavy Duty Vehicles (HDVs) = Trucks

For each of the three major vehicle type categories, hourly VHT distributions were derived by MOVEScompatible speed bins, by jurisdiction (i.e., county), and road type. MOVES calls for 16 speed bins along a 

continuous spectrum of speeds ranging from a low value of 2.5 mph to a high value of 75 mph in 

increments of 5 mph. MOVES also calls for four road types: restricted access facilities (i.e., freeways and 

expressways) in urban and rural settings and unrestricted access facilities (i.e., major/minor arterials, 

collectors and local roads) in urban and rural settings. Average Speed Distribution by the 16 MOVEScompatible speed bins was achieved as follows: 

VHT Distribution to Restricted Facilities (all vehicle type categories):

 Weekday VHT Distribution:

- All Day: Hourly distribution for all vehicles (as derived from the V2.3 Post Processor)

 Weekend VHT Distribution: 

- 11:00 am – 7:00 pm: Distribution across the 13 MOVES-compatible vehicle type categories 

reflecting the 3:00 pm hour on a weekday (as derived from the V2.3 Post Processor)

- 7:01 pm – 10:59 am: Distribution across the 13 MOVES-compatible vehicle type categories 

reflecting the 12:00 am hour on a weekday (as derived from the V2.3 Post Processor)

VHT Distribution to Unrestricted Facilities (all vehicle type categories plus Intercity Bus). Refuse 

Trucks, School Buses and Transit Buses were accounted separately in a section that follows.

 Weekday VHT Distribution:

- All Day: : Hourly distribution for all vehicles (as derived from the V2.3 Post Processor)

 Weekend VHT Distribution: 

- 11:00 am – 7:00 pm: Distribution across the 13 MOVES-compatible vehicle type categories 

reflecting the 3:00 pm hour on a weekday (as derived from the V2.3 Post Processor)

- 7:01 pm – 10:59 am: Distribution across the 13 MOVES-compatible vehicle type categories 

reflecting the 12:00 am hour on a weekday (as derived from the V2.3 Post Processor)

VHT Distribution to Unrestricted Facilities of Refuse Trucks: 

Refuse Trucks operate on a 3-phase cycle: Phase 1 is the period of driving from the dispatch garage to 

trash collection sites; Phase 2 is the period of the actual trash/recycle collection; Phase 3 is the period of 

driving back to transfer stations. Based on the local data provided by Fairfax County, VA, the average 

speed of Phase 1 and Phase 3 is within the MOVES Speed Bin 6 range, and the average speed of Phase 2 

is within the MOVES Speed Bin 2.

Weekday VHT Distribution (Table 2):

- 5:00 am–5:00 pm (Trash Collection): VHT hourly distribution consists of Phases 1, 2 and 3.

- 5:00 pm–5:00 am (On Road Phase): VHT hourly distribution consists of Phase 2.

ROAD TYPE DISTRIBUTION

The Version 2.3 Post Processor accounts for VMT by three vehicle types: passenger vehicles, commercial 

vehicles and heavy duty vehicles. In the MOVES environment, 13 vehicle type categories are identified. 

The challenge was to “expand” the VMT allocations (as percentages of the total) from the three vehicle type 

categories to the 13 MOVES-compatible vehicle type categories. The Version 2.3 Post Processor also 

accounts for VMT by two facility types: restricted access facilities (i.e., freeways and expressways), and 

unrestricted access facilities (i.e., major/minor arterials, collectors and local roads). The VMT allocated to 

each of the three vehicle type categories is also stratified by the two facility types.

The VMT distribution by Vehicle Class Type and Facility Type was done as follows:

 Passenger Vehicles (PVs) VMT percentages (by facility type): From the V2.3 Post Processor applied to 

motorcycles, passenger cars and passenger trucks

 Commercial Vehicles (CVs) VMT percentages (by facility type): From the V2.3 Post Processor applied 

to light commercial trucks

 Heavy Duty Vehicles (HDVs) VMT percentages (by facility type): From the V2.3 Post Processor applied 

to single unit short haul and long haul trucks, and combination short and long haul trucks

 Refuse Trucks and Motor Homes: MOVES default percent value

 Local network VMT percentages – based on local data supplied by bus operators – were applied to 

school, transit and intercity buses

Urban versus rural percentage split factors were subsequently applied to differentiate VMT allocations 

between urban and rural facilities. These factors varied by jurisdiction as they were based on the latest 

Highway Performance Monitoring System (HPMS) VMT data provided by the three state transportation 

agencies. Figure 2 graphically illustrates the process that was followed to allocated VMT percentages by 

vehicle type class and road type in a format that is MOVES-compatible.

Figure 2– VMT Distribution Development Process

SOURCE TYPE POPULATION

The 2011 VIN profile was used for the base year 2011 analysis.

Each vehicle population profile reflects an actual (and unique) composition of the regional vehicle fleet at a 

given point in time. The “raw” 2011 VIN data was decoded using a commercial decoding software program. 

Since the “raw” data were a 100-percent sample of the registered vehicles in the non-attainment area no 

further data expansion was needed. 

The vehicle population distributions – composition and age -- were converted to a MOVES-compatible 

format (i.e., 13 MOVES vehicle types) using the standard EPA-developed vehicle population mapping table

(Table A1 in the Appendix section of this report). 

VEHICLE TYPE VMT

MOVES requires annual VMT by six Highway Performance Monitoring System (HPMS) vehicle types

instead of the 13 MOVES vehicle types. The V2.3 Post Processor produces average annual weekday VMT

estimates by three vehicle types: passenger vehicles, commercial vehicles and heavy duty vehicles. Based

on the VMT percent by 13 HPMS vehicle types and the vehicle registration data, average annual weekday 

VMT in three vehicle types from the V2.3 post processor and the local bus, VMT estimates are split into six 

HPMS vehicle types.

The average annual weekday VMT by six HPMS vehicle types is then fed into the EPA-provided annual 

VMT converter (AAD VMT Calculator HPMS.XLS) (3) with local monthly adjustment factors and weekendday adjustment factors. The converter develops annual VMT in six HPMS vehicle types required as an 

input to MOVES with two additional outputs (i.e., ’monthVMTfraction’ and ’dayVMTfraction’). The local 

“hourlyVMTfraction” is also provided as part of the annual VMT input.

RAMP FRACTION

Local data was used to estimate the local ramp fraction using a method approved by the MOVES Task 

Force. The locally-derived percentage is equal to 8 percent of VHT, the same as the MOVES default value. 

METEOROLOGY

Meteorology data used in the base year 2011 onroad mobile emissions analysis were developed using the 

monthly average hourly data for 2011 for the Dulles and Reagan National airports. Temperature and dew 

point temperature data were averaged for each hour in each month to develop a single set of these two 

parameters for the Washington, DC-VA-MD ozone nonattainment region. Then hourly relative humidity data 

for each month were developed using the above two parameters. In this way, a regional set of hourly 

temperature and relative humidity data were developed for the period January through December for 2011, 

which were used in the MOVES2010a analysis for all counties in the nonattainment region. 

While the annual emissions analysis used meteorology data for the period January through December for 

2011, the ozone season day analysis only used data for July. 

FUEL SUPPLY & FORMULATION

The District of Columbia, Maryland, and Virginia provided fuel characteristics data in the MOVES-ready 

format. 

INSPECTION/MAINTENANCE (I/M) PROGRAMS

The District of Columbia, Maryland, and Virginia provided details of I/M programs in the MOVES-ready 

format.

STATE SPECIFIC CONTROL PROGRAMS

1. Early NLEV: The District of Columbia, Maryland, and Virginia adopted an Early NLEV program, which

is reflected in the base year 2011 emission analysis.

2. Stage II: Varies by area as follows:

 District of Columbia: Refueling vapor program adjustment- 0.9, Refueling spill program 

adjustment- 0.5 (MOVES2010a defaults)

 Maryland: Refueling vapor program adjustment- 0.7, Refueling spill program adjustment- 0.7 

(MOVES2010a Stage II database file - md_stageii)

 Virginia: 

Refueling vapor program adjustment- 0.56, Refueling spill program adjustment- 0.56

3. CAL-LEV II/ZEV Programs: Since 2011 Maryland adopted CAL-LEV II program and as such it is 

reflected in the base year 2011 emission analysis. The following auxiliary files, provided by the 

Maryland Department of the Environment (MDE), were used to model these programs in the Maryland 

jurisdictions:
