AIR-RAIL INTER-MODAL NETWORK DESIGN UNDER HUB CAPACITY CONSTRAINT

Abstract

Recently, while building or expanding of a large hub airport becomes controversial in economic, social and environmental facets, the idea of inter-modal substitution of short-haul air spokes by high-speed trains (HST) becomes a realistic option. This paper aims to analyze what shape of inter-modal network is efficient, and how beneficial it would be on passengers. Genetic Algorithm is applied to find the best mixture of Haneda Airport’s operation capacity allocation to domestic destinations and the spatial configuration of HST network, maximizing the consumer surplus of Japanese domestic inter-city passengers. The result of our analysis shows that HST service of 2400 km as provided in 2000 is essential for keep mobility, and that operation capacity shortage problem at Haneda is solved by additional HST service. The shape of optimal HST network becomes different according to the change of the operation capacity of Haneda.
