ANALYZING INTER-REGIONAL TRAVEL MODE CHOICE BEHAVIOR WITH MULTI NESTED GENERALIZED EXTREME VALUE MODEL

Abstract

Travelers inevitably make multi-modal route choices — a combination of modes making a trip. It is particularly important in the analysis of inter-regional travels, including access modes, trunk modes, egress modes etc. The paper focuses on the mode choice behavior in the entire trip covering each part of the trip. This paper also aims to give contributions to the evaluation of the policies aiming to more efficient and smooth transfer between travel modes. An advanced discrete choice model called “Multi-Nested GEV (MN-GEV) Model” is formulated to capture the correlations among the elements of the inter-modal travel behaviors. The stability of MN-GEV model parameters is also examined to show the capability of the model. It is applied for the inter-regional travel survey data of Japan and the estimation results are compared with other types of discrete choice models.
