• Abstract:
  The U.S. Department of Transportation, John A. Volpe National Transportation Systems Center (Volpe Center), Environmental Measurement and Modeling Division, provided technical support to the National Parks ; Foundation as a part of a National Park Service (NPS) project to evaluate vehicular emissions in the national parks. A Visitor Vehicular Traffic Impact Study (the Study) was performed in three California National ; Parks between August 2002 and April 2003 – Yosemite National Park, Joshua Tree National Park, and Point Reyes National Seashore - in order to collect traffic count, vehicle tracking, meteorological, Inspection and ; Maintenance Program, and fuel program data. This data was processed through the Environmental Protection Agency’s (EPA) MOBILE6.2 modeling software to produce park-specific emission factors, and weekly ; traffic count data was used with these emission factors to produce a weekly emissions inventory for each park. Alternative methods involving modal emissions models were also investigated. Mainly due to their ability ; to take into account park-specific driving cycles, modal emissions models are likely to provide results that are more appropriate for the National Parks. For further emissions modeling, a simplified approach using a ; modal emissions model is recommended. This comparison report contains a technical comparison of the three California national parks emissions inventory input data and instructions on how to produce emissions ; inventories for other parks through a simplified approach.
