Abstract

Improving the Mobility of Non-Drivers Using Proximity to Destinations
Track: Transportation
Author(s): Robert Case

Research had shown that the mobility of non-drivers is significantly lower than that of their driving counterparts, and that land use--specifically proximity to destinations--impacts non-driver mobility. But the impact of proximity to destinations on non-driver mobility had not been directly measured. Therefore, a survey was designed, implemented, and analyzed to measure this impact. In this paper, data from the survey conducted in the Hampton Roads region of Virginia--augmented with a new GIS technique for calculating the attractiveness of nearby destinations--are used to measure the mobility impact of proximity to destinations. The GIS proximity technique combines a component of 4-step transportation modeling with Esri distance measurement. It is the first known study to identify and quantify factors which increase the mobility of all non-drivers (i.e. adults of all ages who do not drive), and the first known study to calculate the impact of proximity to destinations--directly measured--on the mobility of non-drivers.
