  1. The Composition of the Vehicle Fleet in the Metropolitan Washington RegionResults of Applying a Vehicle Identification Number (VIN) Decoder to July 1, 2008 Vehicle Registration DataPresentation to theNational Capital Region Transportation Planning Board April 15, 2009 Technical Committee Item #3

  2. STUDY PURPOSE - Review of trends in region’s vehicle fleet - Assess impacts of market changes - Apply latest planning assumptions in air quality analyses

  3. TECHNICAL METHODS - Obtain data files of registered vehicles in D.C, MD and VA • Apply ‘VIN Decoder’ software to read files and tabulate according to vehicle type, weight, fuel use and year of manufacture • Identify vehicle composition and changes since first use of decoder with 2005 data • Develop input files for EPA’s Mobile 6 model • Re-estimate emissions factors for forecast year analyses in current air quality conformity assessment

  4. STUDY RESULTS • Composition of vehicle fleet in 2008 • Number of registered vehicles • Vehicle type • Cars, SUVs, heavy duty trucks • Hybrids • Age of Vehicles • Changes through time

  5. Data Sources • Vehicle Registration Data for the Washington Region as of July 1, 2008 from DC Department of Motor Vehicles, Maryland Motor Vehicle Administration, and Virginia Department of Motor Vehicles • VINPOWER Vehicle Identification Number (VIN) decoder software from ESP Data Solutions • National vehicle fleet data projections from “Fleet Characterization Data for Mobile 6” by Environmental Protection Agency, September, 2001

  6. Vehicle Type Definitions • Passenger Vehicles (Less than 6,000 lbs): Passenger Cars and Motorcycles • Light Duty Trucks (Less than 8,500 lbs): Sport Utility Vehicles, Pickup Trucks, Panel Trucks • Heavy Duty Trucks (8,500 lbs and above): Tractor-Trailers, School and Transit Buses, Trash Trucks

  7. CONCLUSIONS: 2008 VS. 2005 FLEET Factors Tending to Reduce Emissions: - Hybrid vehicles increasing dramatically (although still small in absolute numbers) - Passenger cars vs. SUVs trends reversed, i.e., new car purchases increasing at the expense of SUVs and light trucks Factors Tending to Increase Emissions: - Fewer new vehicles being purchased - Emissions factors higher as a result, for both VOC and NOx > up to10% higher rates in 2010 > up to 4% higher rates in 2030

  8. POLICY IMPLICATIONS - Policy Initiatives on Capitol Hill (e.g., Cash for Clunkers) - EPA Programs (e.g., heavy-duty truck retrofits and re-powering) - DOE Energy Conservation Programs (e.g., Idle-Reduction Technologies)
