Abstract

In the major operation section of urban railway, there has been occurred habitual delay, and delay propagation and spread to consecutive trains. Therefore, this delay cause the increase of operation time and irregular operation, also the increase of crowd and inconvenience to passengers. The railway operation plan is a promise to passengers and must have reliability. In the case of high frequency urban operation, dwell time have considerable influence on operational headway, so it is very important to efficiently plan and control the dwell time at stations. In this paper, the survey of the research on dwell time for urban railways is presented. The practical estimation model for minimum required dwell time, and the numerical example and validity are proposed.

도시철도 주요구간에서는 상습적인 지연 및 후행열차로의 지연파급확산으로 구간운행시분 증대 및 정시운행 불가, 나아가 혼잡증대로 인해 이용승객이 불편이 가중되고 있다. 운행계획은 승객과의 약속이자 타 자원운영계획과 연계하여 신뢰성이 확보되어야 한다. 고밀도 운행 도시철도의 경우 정차시분이 운행시격에 미치는 영향이 가장 크며, 효율적 서비스계획 수립 시 정차시분의 관리는 매우 중요하다. 본 논문에서는 도시철도 분야의 정차시분 관련 선행연구동향을 살펴보고, 국내 운영기관 환경에서 실용적으로 활용할 수 있는 최소소요 정차시분 추정모델과 실제 현장데이터를 활용하여 수치사례를 함께 제시한다.
