EMISSIONS AND FUEL USAGE BY THE U.S. TRUCK AND BUS POPULATION AND STRATEGIES FOR ACHIEVING REDUCTIONS

This paper presents an approach to modeling the United States truck and bus population. A detailed model is developed that utilizes domestic factory sales figures combined with a scrappage factor as a building block for the total pupulation. Fuel consumption and HC, CO, NO2, CO2 and particulate matter emissions for gasoline and diesel engines are of primary interest. The model details these parameters for the time span 1958-2000 in one-year increments. It is concluded that a combination of the three strategies, substitution of diesel engines for gasoline engines in new vehicles, field retrofit of pre-1968 vehicles, and more stringent emissions restrictions would result in the greatest reductions of fuel consumption and emissions in future years.
