1. The Composition of the Vehicle Fleet in the Metropolitan Washington Region Results of Applying a Vehicle Identification Number (VIN) Decoder to July 1, 2008 Vehicle Registration Data Presentation to the National Capital Region Transportation Planning Board April 15, 2009 ITEM # 11

2. 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. 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. 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

18. 18 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

19. 19 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)
