초록

본 연구는 교통카드자료를 이용하여 승객 OD를 분석하고 서울시 도시철도 최대 혼잡구간인 2호선 외선구간(사당~삼성)의 혼잡도 개선을 위한 통행 수요관리 정책을 제시하였다. 삼성역 이전 목적지 승객과 삼성역 이후 목적지를 가진 승객의 수요를 분리 유도하기 위한 기존 순환선과 삼성역까지 운행하는 단절운행 열차를 혼합으로 운행하는 대안을 제시하였다. 분석결과 순환선 탑승비율이 70%이며 순환선과 삼성행 단절 열차 투입빈도가 1:3일때 최고 11.3%의 혼잡도 개선효과가 있는 것으로 분석되었다. 2호선 혼잡구간을 통과하는 수요를 분리하는 수요관리 대안은 최소의 비용으로 혼잡도를 개선함과 동시에 승객의 쾌적성 개선을 가져올 것으로 기대된다.

This study proposes a policy for urban railway travel demand management system in order to decrease the load factor of the Seoul metro Circle line, particularly for the segment between Sadang and Samsung stations, through analyzing the transit smart card data. We propose mixed train operations of the existing Circle line and a line that goes toward Samsung station in order to transport passengers that have two distinct groups: those with the destination of Samsung station and those with destinations after Samsung station. The introduction of a mixed train operation that encourages passengers passing through Samsung station to take a Circle line train will decrease the congested load factor by 11.3% during the morning peak hours using the mixed train operation of the Circle and Samsung lines. This policy could be an effective method to decrease the load factor and improve the comfort of rail passengers without extra investment in the railway facilities.
