열차 지연 저감을 위한 전방 회차 효과 분석

초록

The delay in train operation is one of the main factors that reduce the efficiency and reliability of urban railway system. This study aims to propose front turning-back scenario and analyze the effect of train delay reduction. The front turning-back scenario is defined as turning a train in the reverse direction of the existing operation line in front of turning-back station. The simulation analysis is performed based on the network and operation data of Shinbundang line under various disturbance conditions. The results show that the front turning-back algorithm can be reduce the average delay time by about 18.3~38.4% compared to normal turning-back operation. Especially, the front turning-back algorithm is expected to contribute to a reduction of the operation delay in the high-density urban railway network.
