An econometric analysis of vihicle use in multivehicle households
Abstract The significance of the multivehicle household in the U.S. has increased substantially in recent years to the point where over 80% of household vehicles holdings are owned by multivehicle households. Despite this fact. traditional travel demand models have not explored the determinants of individual vehicle use in such households, even though knowledge of vehicle usage allocations within household fleets is critical to subsequent fuel consumption forecasts. This paper presents a discussion of vehicle use in multivehicle households and then develops an appropriate modeling specification. The specification consists of a simultaneous equation system which is estimated using a sample of two-vehicle households from a recently conducted national survey. The estimation results proved to be quite satisfactory and the model was applied to forecast policy impacts. The results underscore the importance of income and vehicle fuel efficiency in the allocation of use to household vehicles, and suggests that the ability of multivehicle households to substitute the use of more fuel efficient vehicles for less efficient ones (thereby maintaining higher usage levels) can have potentially significant consequences for traditional vehicle miles traveled (VMT)—price elasticity estimates.
