Integration of Ground Access to Airports in Measures of Inter-urban Accessibility

This report primarily focuses on the spatial variation of air passenger trip times through the dual transport modes, ground access to and flight routing between airports, in an empirical data-driven assessment. Expected journeys from individual census tracts in the contiguous 48 states (and D.C.) are derived by connecting each tract with its neighboring airports at which actual air passenger trips are observed, then the ground access and flight time of each observed air trip is measured, using various empirical sources. Since the locally accessible airports vary across communities, a set of accessible airports is given for each community, which is in turn a base to define the community’s local travel market with airports competing there. A community-specific relative journey time ratio is designed to evaluate the competitiveness of their nearest airport against other local competitors. The estimation allows us to explore potentially vulnerable regions by strong airport competition regarding the leakage problem [when travelers avoid using the local airport in their regions, and use other (out-of-region) airports] to take advantage of lower fares and more convenient airline services, which in the past literature has been largely investigated for multiple airport regions (MARs) within limited geographical boundaries through surveys. This effort is expected to suggest future research sites for investigating passenger travel behavior and airport competition even among local airports.
