AUTOMOTIVE ENERGY FORECASTS: IMPACT OF CARPOOLING, TRIP CHAINING, AND AUTO OWNERSHIP

Using data from a 1970 statewide home-interview survey, base year (1975) automotive fuel consumption is calculated for urban, small urban and rural areas of upstate N.Y., as a function of trip rates by purpose, trip length, auto occupancy, auto ownership and automotive fuel efficiency. The upstate area of N.Y. consumes about 3.0 billion gallons of gasoline annually. Forecasts are then made of automotive fuel use at a 1980 baseline, and the impact of various carpooling and trip chaining policies on automotive fuel consumption. The policies analyzed are those generally given the greatest public support. Results show that, while difficult to achieve, a 25% increase in carpooling for work and shop trips would save about 5.8% of 1980 automative transportation energy. Trip chaining policies oriented at weekday and weekend non-work travel would save 10-13%. Several actions ("carpool coordinators", and "transportation audit") are suggested for consideration as ways to achieve these savings. /Author/
