Optimal Railroad Operations Considering the Complementary Service with Domestic Flights

Abstract

This paper discusses optimal railroad operations considering the complementary service with domestic flights. As an index of consumer's convenience, we formulate the consumer surplus of rail and aviation passengers calculated from the given train frequency on railway links. GA is applied to find the best mixture of number of daily train frequencies for each link maximizing the consumer surplus, with the basis of the given aviation service. We set the service level of aviation links based on the situation in the year 2000 and 1970. From the results of the GA, we show that strengthening the railway service of middle distance band. such as access to airports, is expected, from both viewpoints of travelers' convenience and operators' profitability.
