Abstract

This paper presents a novel application of static traffic assignment methods, but with a variable time value, for estimating the market share of high-speed rail (HSR) in the northwest--southeast (NW--SE) corridor of Korea currently served by air, conventional rail and highway modes. The proposed model employs a time--space network structure to capture the interrelations among competing transportation modes, and to reflect their supply- and demand-side constraints as well as interactions through properly formulated link-node structures. The embedded cost function for each network link offers the flexibility for incorporating all associated factors, such as travel time and fare, in the model computation, and enables the use of a distribution rather than a constant to represent the time--value variation among all transportation mode users. To capture the value-of-time (VOT) of tripmakers along the target corridor realistically, this study has developed a calibration method with aggregate demand information and key system performance data from the NW--SE corridor.
