Planners and researchers increasingly are concerned with how residential environments relate to auto ownership and travel. We quantified accessibility and walkability, to examine relationships of trips and modes to auto ownership and residential location. We applied the results in travel demand modeling for various scenarios, including a recent forecast linking land use and demographic changes, travel behavior, emissions and air quality. We found that where the built environment rates high on such measures as density, connectivity, pedestrian and transit facilities, and other features of highly walkable and accessible areas, people own fewer vehicles but make more trips. Although such environments also are associated with greater likelihood of walking and attendant decreases in motorized modes, driving remains overwhelmingly dominant.
