Abstract
Effects of automobile and transit accessibility on vehicle holding, vehicle type choice, and use, are examined in this study using data from the South Coast metropolitan area. Household-based models are developed for: the total number of vehicles available to the household, the number of vehicles per household member and that 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 assess whether transit accessibility affects auto ownership, vehicle type choice, or use, in such an auto-dominated area as the South Coast region, through statistical analysis of survey data.
