A Comparison into the Factors Affecting Urban Rail Systems: Local, Express, and High-Speed Rail in Tunnels at a Great Depth in a Metropolitan Area

Abstract

In this study, the factors influencing the choice of the type of urban railroad transportation in the metropolitan areas of Korea were analyzed. As the populations of metropolitan areas are expanding, the importance of rail transportation, which has a high travel reliability in terms of travel time, has increased, and various types of railroad systems have emerged accordingly. This study was focused on the choice behavior of travelers on local and express trains that use the same track and differ only in the number of stations and operating times. To compare the choice behavior of travelers between local and express trains, factors such as the waiting time on the platform and the in-car travel time were considered. We also investigated the system choice behavior for an existing express subway and high-speed rail trains in tunnels at a great depth in terms of horizontal access time (walking), vertical access time, in-vehicle travel time, and travel fare. For a high-speed rail built underground at a great depth of 50 m, the stated preference survey was designed, and data were collected in consideration of the Great Train Express being promoted in the Seoul metropolitan area by the Korean government. The results of this study are expected to be considered important data for improving the rail system design from the user’s perspective to increase the demand for urban rail transportation in metropolitan areas.

How to Measure the Impact of Walking Accessibility of Suburban Rail Station Catchment Areas on the Commercial Premium Benefits of Joint Development

“…The three-dimensional walking network can improve the walking accessibility and increase pedestrians' willingness to choose routes by reducing the OD distance [26]. Enhancing the integrity of the pedestrian network can counter the effects of traffic congestion, and the city's surface streets should be integrated with underground spaces, above-ground flyovers, and public transportation infrastructure [27].…”

A conceptual non-stop operation strategy for urban rail transit: a case study of São Paulo’s monorail line

“…Non-stop does not require significant investments in infrastructure, such as the construction of new rail tracks, or lines, which can be expensive and less attractive if built deep into the ground, thereby taking longer to reach (Lee et al , 2021). However, it does require locomotives capable of dynamic coupling (DC) – coupling and decoupling at non-zero speed – allowing passengers to safely walk over to another wagon to either skip or stop at the next station.…”
