STUDY ON A METHOD FOR MEASURING INDIVIDUAL MOBILITY USING INDIES OF AVAILABILITY OF TRAVEL MODES

Abstract

This study aims to propose a method for measuring individual mobility using new indices of availability of travel modes and examine the effectiveness of those indices. We first calculated the indices of availability of three travel modes, walking, driving a car and a car passenger, for each resident in a housing development area in the suburbs of Kobe City, based on our questionnaire survey data. As a result, residents of each age group could be classified into mobility groups which have the similar levels of availability indices, and we showed the diversity of their mobility within each age group. Next, we tried to combine the above availability indices with traditional gravity-based accessibility measures to retail stores and hospitals by residents which were calculated in the study area, and demonstrated the necessity of reflecting the diversity of individual mobility within each age group on evaluating their accessibility.
