ESTIMATION OF CITY AND HIGHWAY SHORTFALL FACTORS FROM COMPOSITE SHORTFALL RELATIONSHIPS
The expansion and refinement of existing techniques used to quantify the differences or shortfall between fuel economy measured on the EPA test procedure and fuel economy achieved by consumers on the road. A method was developed that allows the specification of separate adjustment factors for the EPA urban and highway fuel economy values. The 1980 General Motors in-use fuel economy data base was used because participants were requested to indicate the percent city driving experienced since their last fuel purchase. All results were communicated through a series of letter reports. After a brief summary of the intent and results of the project, these letters are presented in chronological order.
