Logsum-type space-time accessibility measures that consider two-stage decision-making

Abstract

This paper develops logsum-type space-time accessibility measures that consider two-stage decision making and discusses the plausibility of the measures. First, we formulate the accessibility measures, employing a nested logit modeling framework. Then, we investigate the plausibility of our proposed measures through a case study. Specifically, we use the proposed measures to analyze university students' space-time accessibility to shopping opportunities. Based on the results of the case study, we argue that the space-time accessibility measures proposed in this paper can adequately gauge the degree of individuals' space-time accessibility.
