초록

기존 수도권 광역철도는 운행시간이 많이 걸리는 완행 위주의 운행을 하기 때문에 통행시간 측면에서 타 교통수단과의 경쟁력이 저하되고 있는 실정이고, 도로교통을 철도로 유인하는데 한계가 있기 때문에 급행열차 운행을 확대 운영해야 한다는 사회적 요구가 지속되고 있다. 특히 수도권 북부와 수도권 남서부 방면은 대도시 생활권 확대로 광역교통수요 증대에 따른 교통 혼잡 가중 및 통행시간 증가 등 사회적 비용이 과다 발생되고 있어 서울도심을 연결하는 급행 기능의 대중교통망체계가 필요하다. 국내에서 가장 효율적으로 급행화를 운행하는 노선은 서울지하철 9호선이며, 김포공항에서 고속터미널까지 27분 소요됨으로써 완행 44분 대비 약 40% 시간 단축 효과가 있고 혼잡도가 최대 240%에 달할 만큼 이용객의 선호도가 상당히 높다. 본 연구의 기술적 결과들은 광역철도의 급행화 방안의 수행을 위해 기여할 수 있을 것이라 기대한다.

As the existing metropolitan area metropolitan railway operates on a one-to-one basis, which leads to long travel times, its competitiveness with other means of transportation is deteriorating. Since there is a limit to attracting road traffic by rail, there is a continuing societal demand to expand express train service. Especially in the northern and the southwestern parts of the metropolitan area, a public transportation network system with express function, connecting to the city center of Seoul, is needed because of the social cost of the increase of traffic congestion and the increase of the travel time. The most efficient express service in Korea is Seoul Subway Line 9, which runs in 27 minutes from Gimpo Airport to the high speed terminal; this is a 40% shorter time compared to 44 minutes by car; the congestion in this area is up to 240%, so the preference for this train is quite high. The technical results of this study are expected to contribute to the implementation of an express service metropolitan railway.
