The capability of regional and seasonal factors to account for the variation observed in on-road fuel economy shortfall is examined. The analysis characterizes the seasonal trends in geographic regions of the US and develops a preliminary regionalization procedure. A predictive model of the regional/seasonal variations in shortfall from national annual-average conditions was developed. The regionalization procedure incorporates three major in-use fuel economy effects: vehicle-specific intensity of use (average miles per day); cyclical monthly variations for three US temperature zones; and annual differences associated with local population procedure is demonstrated using the General Motors 1980 Postcard Survey of in-use fuel economy.
