Air-Rail Inter-modal Network Design under Hub Capacity Constraint

抄録

This paper aims to analyze what shape of inter-modal network is efficient in Japan, and how beneficial it would be. Genetic Algorithm is applied to find the best mixture of Haneda Airport's slot allocation to other destinations and the spatial configuration of high-speed train network, which maximize the total consumer surplus of Japanese inter-city domestic passengers, under given combinations of total slots number and total HST lines. The result of our analysis shows that HST service of 2,400km is essential for keep mobility, but Haneda slot shortage is solved by additional HST service. The shape of HST network changes from centralized one to local feeder type, when stronger substitution is expected due to strict Haneda slot capacity.
