SUBTASK V REPORT: CORRELATION OF FUEL ECONOMY AND VEHICLE USE. ANALYSIS MEMORANDUM

The purpose of this analysis memorandum is to determine how changes in vehicle miles traveled (VMT) level influence motor vehicle fuel economy. The motivation for, and implementation of, data selection and screening procedures are described. The methodological framework of the analysis is also developed. Development of the correlation function is presented, beginning with an improved estimate of the AMPD component for the DOE regionalization study. The form of the correlation's temperature sensitivity is determined as an intermediate stage of the analysis and investigation of non-temperature effects is conducted. The final analysis produces a correlation function that is sensitive to ambient temperature, the average AMPD level of the vehicle, and vehicle age. To illustrate the application of the gpm/AMPD correlation, a brief calculation based on estimating AMPD-standardized gpm values for analysis of in-use fuel economy shortfall is presented.
