MOVES
MOtor Vehicle Emission Simulator
State-of-the-art modeling framework
Will replace current models (MOBILE & NONROAD)
and expand capabilities
Designed to allow easier incorporation of large
amounts of in-use data from a variety of sources
- MOBILE structure limited ability to incorporate new emissions
data
-------
Q vvEPA
Why is EPA developing MOVES?
CAA requires EPA to regularly update emission
factors and emission factor models
FORTRAN code used in MOBILE6.2 is obsolete and
increasingly difficult to maintain
Modular database structure more modern, easier to
update with new emissions, fleet and activity data
MOVES will eventually incorporate functions of the
current NONROAD model, providing a single,
comprehensive modeling system
-------

vvEPA
Why is EPA developing MOVES?
National Research Council 2000 review of EPA's
mobile source modeling program included several
recommendations that are addressed by MOVES:
- Support for smaller-scale analyses (project-level analysis)
- Improved characterization of high emitters, heavy-duty
vehicles and nonroad sources
- Improved characterization of particulate matter and toxics
- Improved model evaluation and uncertainty analysis
- Improved ability to interface with other models

-------
v>EPA
MOVES Has a Graphical User Interface
(MOVES can also be executed from a command line interface without
use of the GUI, for batch or unattended operation) o
8
-------
New Software Structure
MOBILES.2
- Written in Fortran, runs in DOS
- Many data elements hard-coded (difficult to modify/update)
MOVES
- Java/MySQL software
- Data elements stored in database tables (easy to
modify/update)
-------
More Flexibility
MOBILE6.2
- Gram/mile emission factors
- Fixed output formats
MOVES
- Gram/mile emissions factors (grams/time for some processes)
- Total emissions: inventories for specific areas and time
periods
- Easily customizable output (many levels of
aggregation/disaggregation possible)
-------
vvEPA
Multiple Geographic Scales
MOBILES.2
- Emissions rates based on regional-scale trip patterns (no
specific geographic area)
MOVES
- Emissions inventories from national level to county level to
project level
- Lookup table option for emission rates
-------

Modal Emissions
MOBILES.2 rates based on aggregate driving
cycles
MOVES rates based on "operating modes"
- Second-by-second activity is captured by the model

MOVES Uses New Data
^^M
Activity
- In-use vehicle trip patterns
- Rural area activity data
Light-duty vehicles
- Assessed millions of light-duty vehicles
- Landmark gasoline PM study (Kansas City)
- Remote Sensing Data
Heavy-duty vehicles
- More than 100 in-use vehicles from VWU
- New on-board real-world driving data from over 300
vehicles

Energy and GHG analysis
MOBILES.2 had simplistic fuel economy and CO2
calculations
MOVES is designed from the ground up as an
energy consumption model
Also estimates greenhouse gases: CO2, methane,
nitrous oxide, and CO2 equivalents of these
While the energy and emissions rates are still
officially "draft", this is the best available tool for
this type of analysis

How Do Emissions
Estimates of Draft
MOVES2009 Compare to
MOBILE6.2?
15
-------
* C.
vvEPA
Early Draft MOVES Results
Data collected since MOBILE6 released drives differences
between MOVES and MOBILES
National trends
- HC and CO emissions similar or lower than MOBILE6.2
- Total NOx emissions higher than MOBILE6.2
- Total PM emissions substantially higher than MOBILE6.2
Local results may vary
- Local fleet mix, fuels, activity are important
- Temperature drives PM emissions
For attainment analysis, relative change in emissions
between base year and attainment year is more important
than absolute emissions
16

c/t v
Q vvEPA
Why are emissions different?
^^^^^^^^^^^^^^^^m
New car and light truck emissions data
• New heavy truck emissions data
• New emissions processes not included in
MOBILES
• Updated fuel and vehicle standards
17
-------
Q vvEPA
Significant new data in MOVES
Updated emission rates
- Test results on millions of vehicles considered for MOVES
• Passenger Cars & Trucks
• Heavy Duty Trucks
New fleet & activity defaults
- National defaults:
• Vehicle fleet from state registration data, VIUS
• Vehicle Miles Traveled (VMT) from HPMS
• Driving patterns from instrumented vehicle surveys
- For local modeling, local data is likely to be most accurate &
up-to-date

Extensive analysis of Car & Light
Truck emissions
^^^^^^^^^B
HC/CO/NOx rates based on - 70,000 vehicles
randomly selected from Arizona IM program
- Able to tease out emissions from I/M and non I/M areas
Checked against data from multiple sources
- I/M data from Illinois, New York, Missouri and Colorado
- Roadside remote sensing data from several cities
- Kansas City Study
Extended to newest technology vehicles using
compliance data
- In-use emissions data manufacturers required to collect
- About 2,000 laboratory tests per year ,.«

vvEPA
Gasoline PM a major focus
Landmark study conducted in Kansas City 2004-05
to address need for improved gas PM estimates
- Collaboration between EPA, DOE, DOT, States, Auto/Oils
496 gasoline light-duty cars and trucks tested
- Model Years 1968-2005
Summer and winter testing
- ~ half of the vehicles tested each season @ ambient temps
- 43 vehicles tested in both winter and summer

What we've learned about Car &
Light Truck emissions
^^^^^^^^^^^^^
New standards have been successful in reducing
deterioration of HC/CO/NOx emissions
On-Board Diagnostic (OBD) systems are a
contributing factor to lower deterioration
- Owner response to repair identified malfunctions is better than
MOBILES projected, particularly in non-l/M areas
Gas PM emissions are much higher than MOBILES
projected
- Higher in-use deterioration
- Significant increase at cold temperatures

Heavy Duty Diesel emissions
updated based on real world data
MOBILES relied on certification data
- Engine tests only
Much research on in-use trucks since MOBILES
- CRCE-55
• 75 trucks on chassis dynamometer
• Only real-time PM data of it's kind
- On-Board Measurement: -350 trucks on road
• Provided most robust assessment of NOx emissions available
Extended idle, crankcase, starts, tampering & mal-
maintenance factored in (not in MOBILES)
23
-------
vvEPA
What we've learned about Heavy
Duty Diesel emissions
NOx
- In-use emissions moderately higher than MOBILES projected
- Extended idle (hoteling) emissions are significant
• And projected to grow as percent of NOx inventory
PM
- Significant speed effect
• MOBILES did not model any speed impacts
• Large increase in emissions at lower speeds vs. MOBILES
- Crankcase emissions significant

Analysis of Local Area Impacts
^^^^^^^^^^^^^^^^^M
Did preliminary comparison of MOVES and
MOBILES using surrogate local data to represent 3
different urban counties
- Local data very limited, may not be consistent with what states
will actually use
Local data varied by:
- Fleet age distribution
- Fraction of light and heavy duty VMT
- Local fuel specifications
- Meteorology
- Other input factors
25
-------
I/M program data shows MOBILE6
underestimated NOx emissions from
light trucks
On-road data on heavy trucks shows
higher emissions than MOBILE6
estimated from cert data
Extended idle emissions become
significant share of heavy-duty
inventory in future

What It Means
Higher NOx and PM emissions mean mobile sources have
bigger role in attainment
Percent reduction from base year is key to attainment
analysis
- PM2.5 shows higher overall emissions and higher % reductions
• Effect on attainment demonstrations could be positive
- NOx shows higher overall emissions but lower % reduction
• Harder to show attainment
• Future NOx control measures will have a bigger impact
States may need to redo some motor vehicle emissions
budgets to meet conformity requirements with MOVES
30

Q vvEPA
I/M Effects In MOVES
^^^^^^^^^^^^B
Benefits are comparable to MOBILE6 now,
but will shrink over time.
- Conservative M6 OBD assumptions not supported
by data
• CRC did comprehensive survey of MIL response in non-l/M
areas
• Found high response even after warranty
- Our analysis of I/M program data confirms that OBD
works

-------
vvEPA
Draft MOVES2009 - Limitations
Draft model
- No official use requiring Draft MOVES2009
- Cannot be used for SIPs or conformity analyses
Does not include all data or features planned for
official MOVES2009 and has known and unknown
bugs, for example:
- Motorcycle emissions not yet included
- Plan to add more flexibility for VMT input
- Known bugs in refueling vapor and spillage processes and
project level scale
35
-------
&EPA
Why release Draft MOVES2009?
^^^^^^^^^^^^^^^^m
Help us identify problems with MOVES
Provide feedback on whether MOVES meets user
needs
- What we can do to improve it?
Identify guidance issues
Start learning MOVES now to be ready to use final
MOVES2009 as soon as it is released
- Use MOVES2009 for SIPs due in 2012 and 2013
36
-------
vvEPA
Official MOVES2009
Official MOVES2009 planned for release at the end
of 2009
Will be official version of MOVES foron-road
vehicles outside of California
Use will be required for:
- State Implementation Plans (SIPs)
- Regional conformity analysis
• Following regional conformity grace period of 3 to 24 months
- Project level conformity analysis for PM and CO
• Following project level conformity grace period
• NEPA analysis (e.g., air toxics)
37
-------
vvEPA
Easing the Transition to MOVES
^^^^^^^^^^^^^^^^^^H
Improved handling of different domain sizes
- Added GUI for nonattainment area and project level analysis to
allow users to specify local inputs
Developed data importers which:
- Ease conversion of MOBILE inputs to MOVES inputs
• More to come
- Allow input of data as text files
Writing future guidance documents
- Technical guidance will address when and what type of local
input is needed
38
-------
vvEPA
Levels of Analysis in MOVES
^^^^^^^^^^^^^^^^^^m
• MOVES is designed to work at macro, meso, and
micro scales
These translate into different geographic domains:
- National
- Nonattainment Area or County
- Project
Added GUI to Draft MOVES2009 for local inputs for
nonattainment area and project level analysis
39
39
-------
vvEPA
Default County Level Data in Draft
MOVES2009
National domain will produce results for the nation,
specific states, or specific counties
- Current default county level data in MOVES is a mix of
national defaults, national data disaggregated to county level
with adjustment factors, and local data from various sources
- Users cannot rely on default county level data to be accurate
or up to date and it should not be used for SIPs or conformity
analysis
For SIPs and regional conformity analysis, users
should select the county domain and enter local
data using the County Data Manager
40
-------
vvEPA
What Are MOVES Data Importers?
^^^^^^^^^^^^^^^^^^^^^
Software interfaces that can create alternate databases, tables,
and data records for use by MOVES
Draft MOVES2009 includes data importers to simplify creation
of local input files
Advantages
- Do not require knowledge of database commands and syntax
- Can assure the updates are made only to the appropriate tables
- Can require complete information from users, preventing data
gaps
- Can include some error checks
- Can be designed to convert data from MOBILES to MOVES format
41
-------
vvEPA
Future Guidance Documents
EPA expects to release several guidance
documents that will help with the transition for
final MOVES
- MOVES Technical Guidance for SIPs and conformity
- Project Level Conformity Guidance for PM
- MOVES SIP and Conformity Policy Guidance
Will release draft guidance for comment sometime
after release of Draft MOVES2009
Final guidance documents will be available when
Official MOVES2009 is released

Road Types
For running emissions, county-level VMT
is distributed to four road types:
Rural Restricted Access (freeways and Interstates),
Rural Unrestricted Access,
Urban Restricted Access (freeways and Interstates),
Urban Unrestricted Access
A fifth road type, "off-network", is
included to capture start, evaporative
and extended idle emissions
- This is not the same as "off-network" vehicle
activity in the travel modeling world.

Emissions by Source, Age, Mode
AMOVES uses a different rate for each
combination of:
- Source,
Age group, and
Operating mode
\
Sas-LDV-MY1998 8-9 years "low-speed" coast
eas-LDT-MV2002 4-5 years "cruise/accel" (speed 25-50 mph, VSP 12-15

How MOVES handles vehicle
activity - Definitions
Vehicle Specific Power (VSP) - a measure of the
energy the vehicle is using at a moment in time
- Affected by acceleration, road grade, resistance, etc.
Operating Mode - what the vehicle is doing, i.e.,
accelerating, braking, cruising, idling
- Vehicles use different VSP in different operating modes
- MOVES defines 23 operating mode bins - combinations of
speed and VSP for different running conditions plus additional
operating modes for starts and evaporative emissions
Drive Cycle - a second-by-second description of
vehicle activity overtime, typically including
multiple operating modes
62

&EPA
Modal "Binning" Approach
^^^^^^^^^^^^^^m
Any driving pattern can be modeled
- Adds major flexibility compared to MOBILE
Allows direct use of data from many sources
Provides common emission rates for all scales
Independent validation has shown good results
even for macroscale application
64

-------
vvEPA
Running Operating Modes in
MOVES
MOVES uses second-by-second emissions data
categorized in operating mode bins based on
combination of speed and VSP
MOVES includes default operating mode
distributions based on typical driving cycles
- Different road types in MOVES have different default operating
mode distributions
Users can create other operating mode
distributions based on other driving cycles
- Unlike MOBILE, any driving pattern can be modeled in
MOVES

New Analysis Opportunities
Modal emission structure allows calculation of "Project-
level" emission changes
- Changes in operating mode distribution -> changes in emissions
Includes an "importer" to help users input project-specific
information on driving activity
- Users can enter operating mode distribution or driving pattern by link
Areas will want tools to estimate how changing road design
affects operating modes
- Adding lanes?
- Synchronizing signals?
- Replacing stop signs with rotaries?
Creates need to better characterize driving patterns -
MOVES defaults may not characterize local patterns, esp project level

anything other than all months, days and hours will cause
problems. If you choose the Time Aggregation Level Year, you
must select all months, days and hours.
Similarly, if you choose the Time Aggregation Level Month, you
must select all days and hours. If you choose the Time
Aggregation Level Day, you must select all hours.

The Calculation Type of Emission Rates on the Scale panel
will produce emission rates only for the Exhaust Running
process.
If you select only the brake wear and tire wear toggle boxes for
PM, the Distance Traveled toggle box will be inaccessible. You
will need to select another pollutant in the Running process in
order to obtain vehicle miles traveled information along with brake
wear and tire wear emissions

What Should You Do Now?
Update computer hardware
- Dual-core processor (faster is better)
- At least 1 GB memory (more is better)
- At least 40 GB storage (more is better, output files can be
very large)
- Consider setting up a distributive network (specs of
"master" computer are key)
- Windows XP or 32-bit Vista
• Current version of MySQL does not work on 64-bit Vista

What Should You Do Now?
Build staff expertise in relational databases and
MYSQL
- Not needed for simple runs
- Some basic knowledge gives users flexibility to customize
outputs and view inputs
- In-house expert would be helpful for more advanced
analysis
