Abstract

With the aim of promoting the use of metropolitan railways, the present research developed a mode choice model for evaluating its competitiveness against passenger cars. A case study was carried out with Gyeongeui and Joongang line, and the area of interest was the direct operating railway between Ilsan and Guri station where the two lines intersect. The mode choice model was a disaggregate behavior model which used Stated Preference (SP) survey data, and the plot of competition was between private passenger cars and express trains. As a result, the mode choice model was established, and this model was used to analyze characteristics of passengers' time value and elasticity. It was shown that reducing travel time is more efficient than reducing travel cost when it comes to operating express trains in metropolitan railways. Therefore, policies designed for activating the use of metropolitan railways should expand direct operating service of individual lines and run more express trains in order to minimize transfer and in-vehicle time.

본 연구는 광역전철 활성화를 목표로 승용차 대비 경쟁력 평가를 위한 수단선택모형을 개발하였다. 연구대상 노선은 수도권의 경의선과 중앙선이며, 열차운행 구간은 두 노선을 연결하는 일산역부터 구리역까지 설정하였다. 수단선택모형은 잠재선호조사(SP) 자료를 이용한 개별행태모형이며, 교통수단선택의 경쟁구도는 승용차와 급행열차이다. 연구 결과, 수단선택모형이 적정한 수준으로 도출되었으며, 이를 이용하여 통행자의 시간가치와 탄력성 값이 나타내는 특성을 분석하였다. 분석결과 광역전철에서 급행열차를 운행할 경우에는 통행비용의 감소보다는 통행시간의 단축에 주안점을 두는 것이 더욱 효과적으로 나타났다. 또한 이 같은 측면에서 개별노선간의 직결운행을 확대하고 급행열차를 운행하여 환승시간과 차내시간을 줄여주는 정책 추진이 요구된다.
