Effect of Block Division for Next-Generation Train Control to Mitigate Delay Propagation

Abstract

The mitigation of delay propagation owing to excess dwell time at stations is crucial for ensuring stable transport in high-frequency urban train services. Previously, we assumed that only one train could enter the entire station section; however, the fixed block section should be divided to mitigate further delay propagation. In this paper, a novel control method is proposed to mitigate delay propagation with multiple block sections at a station. We numerically verify the effectiveness of reducing the delay time based on case studies. The results reveal that dividing the station section into multiple block sections can further mitigate delay propagation. Moreover, the results show that the block section at a station should be equally divided.
