Abstract

This paper attempts to develop a method which combines a subway system with a feeder bus system in order to increase the efficiency of the performance of the subway system. The 'feasible region' where a subway system is more desirable than a conventional bus in its travel time far the CBD-bound trip is determined and the service-specification models of the two systems in this region have been formulated and analyzed in an aggregate manner. The model developed in this study is applied to the Subway Line No. 1 in Seoul. The result obtained in the analysis indicates that the combined system can be guaranteed as a desirable mode in the point of travel time and cost within the feasible region. The concept of the model will lead to a proper assessment of the system's potentials for the choice of an optimal combination of the existing transport technologies.
