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 findings as the backup information for further policy implementations in order that both existing airports, Haneda and Narita, are effectively utilized. Stated preference experiments were conducted using internet-based questionnaire survey. Experimentally control combinations included three attributes: airfare; access time; and flight frequency. Respondents were asked to choose their most preferable air tickets from choice sets as they made their decisions between two airports. We conducted a cluster analysis in order 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 in overall airport choices, especially for domestic experiments; and (b) frequency of service is a less significant factor.
