Abstract

Recently, the building of an intermodal transportation system has become the most important policy in the establishment of a national-wide sustainable transport system. In the case of rail and public transport, an intermodal connecting improvement policy is essential due to the lack of trip completeness. In particular, high-speed rail has brought dramatic changes to the transportation system in Korea and the idea of high-speed rail stations as major transportation nodes to be linked to various travel modes needs to be analyzed in terms of an intermodal network. Thus, this study proposes a new connectivity analysis method to objectively and quantitatively evaluate intermodal connecting performance for high-speed rail in terms of an intermodal network around high-speed rail stations. Seoul, Busan, Ulsan, and Sin-gyeongju stations were designated for a range of spatial analyses; detailed connecting performance indexes of travel modes connecting high-speed rail stations, and the influence sphere of these stations are analyzed, except for internal transfer facilities. Finally, this study proposes a connectivity analysis method that applies the structural equation model and develops a connectivity index.

국가 전체의 지속가능한 교통체계 확립을 위한 연계교통체계의 구축이 중요한 교통정책으로 대두되고 있고 철도 및 대중교통은 통행의 완결성 부족으로 인해 수단간 연계성을 고려하는 것이 필수적이라 할 수 있다. 특히, 고속철도는 우리나라 교통체계의 획기적 변화를 가져왔고 고속철도역은 다양한 수단이 연계되어야 하는 중요한 교통 결절점으로 수단간 연계교통망 차원에서 분석이 필요하다. 이에 본 연구는 고속철도역의 연계교통망 차원에서 고속철도와 연계교통수단의 연계기능을 객관적이고 정량적으로 분석하기 위한 새로운 연계성 분석 기법을 제시하였다. 서울역, 부산역, 울산역, 신경주역을 공간적 범위로 설정하였고 고속철도 역사내의 내부환승 시설을 제외한 고속철도역과 영향권내 기 종점간을 연결하는 연계교통수단의 세부 연계기능 지표를 조사 분석하였다. 구축된 자료를 이용하여 구조방정식 모형을 적용한 연계성 분석 기법을 제시하고 연계성 지표를 개발하였다.
