USE OF DISAGGREGATE DATA TO EVALUATE GASOLINE CONSERVATION POLICIES: SMALLER CARS AND CARPOOLING

A microdata base of vehicle ownership and use characteristic was built from 7581 interviews of Michigan applicants for renewal of driver's licenses taken throughout the state in 1976. Analyses of gasoline efficiency in occupant kilometers per liter suggested that the greatest potential for conservation policy was to be found in commuter carpooling and a shift to smaller cars. Six scenarios for carpooling and smaller cars were defined in sufficient detail to exclude types of trips or classes of vehicle users for which these policies would present significant difficulties. The scenarios were run aggainst the 1976 data to calculate the gasoline savings and improvements in occupant kilometers per liter obtainable in the best case. Smaller reductions in liters were found than would be predicted from gross estimates, but considerable consistency was found in the pattern of hypothetical responses of different sub groups of drivers distingushed by income or the urbanization of their home area, despite large differences in gasoline consumption. It is suggested that suburban drivers could provide 25 percent more gasoline savings than the statewide per capita average under the most optimistic scenarios analyzed. It is also suggested that the microdata techniques be calibrated to externally measured behavioral data on travel and conservation choices. (Authors)
