Stated Preference Analysis of Air Travelers' Multiple-Airport Choice Behavior in Tokyo Metropolitan Area

Abstract

The objective of this research is to investigate the main factors underlining air travelers' choice behavior in Tokyo Metropolitan area's multiple-airport system and apply these finding as the backup information for futher policy implementations in order that both existing airport are effectively utilized. Stated preference experiments were conducted using internet-based survey. Experimentally controlled combinations included three attributes: airfare; access time; and flight frequency. Respondents were asked to choose their most preferable air tickets as they make their decisions between two airports. We conducted a cluster analysis to segment the respondents by their attitudes and estimated a discrete choice model for the respondents representing the population living in the Tokyo Metropolitan region. The results indicate that: (a)airfare and access time are significant factors, especially in domestic experiments; and (b) frequency of service is less significant factor.
