Effects of travel time and cost on the frequency and structure of automobile travel. Paper prepared for the 55th Annual Meeting of the Transportation Research Board TRB, Washington, D.C., January 1976.

Automoblie operating costs were found not to have a statistically significant effect on either the frequency of non-work automobile driver travel by households without access to transit for non-work travel or the frequency of automobile drivers visits to non-work destination by these households. This suggests that changes in automobile operating costs may have little effect on the frequency of non-work automobile travel by households that do not have access to non-automobile modes of transportation.
