Abstract:

This data system, designed by the Oak Ridge National Laboratory (ORNL) and funded by the U.S. Department of Energy (DOE), monitors information on every light-duty vehicle (automobiles and light-duty trucks) sold in the United States since model year 1976. The data are specified in two ways. One way is on a model basis (i.e., engine and transmission combinations) and includes data on city, highway, and combined fuel economies; engine size; drive-train; fuel type (gasoline or diesel); interior volume; body type; and other vehicle attributes. The other way is on a make basis (e.g., Ford Escort, Oldsmobile 98) and includes data on sales; Environment Protection Agency (EPA) size class; the sales-weighted fuel economy; sales-weighted interior volume; sales-weighted engine displacement (cid); curb weight; and other attributes. Although it can be used as a data retrieving tool, this data system has more extensive capabilities and can be used: (1) to calculate market shares, sales-weighted fuel economy, sales or sales-weighted vehicle characteristics by EPA's size class, model year(s), manufacturer(s), manufacture division(s), and vehicle type (cars, light trucks, or combined); and (2) to list makes by user-specific criteria. The current version of the data system is completely managed by the PC Statistical Analysis System (SAS) software on IBM PC's or IBM-compatibles. Additional aspects of the system are discussed.
