PROJECTIONS OF AUTOMOBILE OWNERSHIP AND USE BASED ON HOUSEHOLD LIFESTYLE FACTORS

摘要

The purpose of this research is to project to the year 2025 the total number of automobiles that would be owned by American households, (total ownership) and the total number of miles that these vehicles would be driven per day (total use) given certain assumptions about the future of U.S. society. These assumptions relate to demographic, economic, and geographical attributes of U.S. society which are relevant to the automobile. The impacts of these assumptions have been analyzed via a set of projection models which explicitly recognize the relationship between these particular attributes of society and the automobile.nPart I of this report presents an overview of the research. The results from the projections are presented in Part II. The methodology used to generate these projections is discussed in some detail in Part III.
