Center for Activity Systems Analysis

This study uses data from the South Coast metropolitan area in Southern California to examine the effects of automobile and transit accessibility on vehicle holding, vehicle type choice and vehicle use. Household-based models are developed for the total number of vehicles available to the household, the number of vehicles per household member and per driver in the household, the choice of vehicle type for the most recently acquired vehicle and its use in terms of annual mileage. In each model, indicators of accessibility by auto and that by transit are introduced along with residential density and other indicators of residence area, and household attributes. The objective is to use statistical analysis of survey data to assess whether transit accessibility affects auto ownership, vehicle type choice or use in an automobile-dominated area.
