초록

대도시 고밀도 도시철도에서는 상습 열차운행 지연과 혼잡으로 승객의 불편과 불만이 커지고 있다. 도시철도는 열차운행의 비정규성과 수요의 불확정성 등 지역간 철도와는 다른 특성을 가지고 있다. 도시철도 운영회사에서는 실적자료를 기반으로 열차운행품질과 혼잡도와 같은 서비스품질을 집계하여 관리하고 있다. 그러나 수요와 승객행태에 따라 열차운행이 동적으로 변하는 특성을 가지고 있어 실제 느끼는 서비스품질을 표현하기에는 한계가 있다. 본 논문에서는 승객 관점에서의 서비스품질을 계량화하고, 도시철도에서 수요에 따른 정차시분 및 열차운행상태의 동적변화를 예측할 수 있는 시뮬레이션 방법과 지연/혼잡 해소방안에 대한 실제 사례를 기반으로 운행서비스품질의 변화를 예측할 수 있는 방법론을 제시한다.

In the major operation sections of the urban railway, there has been habitual delay, and delay propagation; another problem is the increase of crowds and of inconvenience to passengers. The urban railway has different characteristics from rural railways, such as uncertainty of demand and irregularity of train operation. In urban railways, recently, operators manage quality indicators of service using operation results, such as the delay of train operation and the congestion of trains. However, because the urban railway has characteristics in which demand, passenger behavior, and train operation mutually affect each other, it is difficult to express the quality of service that passengers actually feel. In this paper, we suggest a quality indicator of service from the viewpoint of passengers, and present a demand responsive multi-train simulation method to predict dynamic dwell time and train operation status; we also use simulation results to consider changes in the quality indicator of service.
