THE INFLUENCE OF THE PRICE OF GASOLINE ON VEHICLE USE IN MULTIVEHICLE HOUSEHOLDS

Two-thirds of the households in the United States that own motor vehicles own two or more. Multiple vehicle ownership permits households to substitute travel by fuel-efficient vehicles for travel by inefficient vehicles in response to higher fuel prices. Travel demand equations were estimated for one-, two-, and three-vehicle households by using disaggregate data from a monthly diary of vehicle use from April 1978 to March 1981. Three individual equations and a combined equation for small cars, large cars, and trucks were estimated. Price and fuel efficiency elasticities were allowed to vary according to the type of other vehicle owned by the household. In response to a 25 percent increase in gasoline price, the model predicts a 5 percent decline in vehicle use, but only a 0.2 percent increase in overall fuel efficiency is due to shifts to smaller vehicles.
