| Abstract |
Currently, high-speed rail KTX has been actively operating since its opening in 2004. However, as the number of operations is mostly concentrated in major bases (metropolitan cities) such as Seoul, Gwangju, and Busan, the demand for use varies greatly according to the number of operations on each line. In this study, by reviewing the current status of KTX operations for high-speed rail, the justification for expanding the number of operations was presented by analyzing the distance per rail extension, reviewing the future development plan, and the utilization rate saturation for areas with a relatively small number of operations. In addition, Pohang Station was selected to conduct a detailed analysis of related routes, and by analyzing the justification for expanding the number of operations, a more rational expansion plan was suggested. As a result of analysis in this study, in the case of the Donghae Line, the number of users per railroad extension (km) was the highest at 49 people/day compared to lines with similar number of operations, and the utilization rate was also calculated to be the highest at 104 % compared to other regions. In addition, since a number of future urban development plans are being promoted to secure the number of residents and workers that affect the number of users, it is considered that the justification for expanding the number of train operations was secured. Through this study, it is expected that the number of reasonable operations will be secured by comprehensively judging various matters other than the number of users for simple profit. |
