A Train Traffic Control Algorithm for Metropolitan Area Lines

Chikara HIRAI, Norio TOMII


  In the metropolitan areas of Japan, a large number of commuters concentrate in rush hours. Once a train has delayed for some reasons in these areas, the delay tends to augment. This is because the larger a train delays, the more passengers wait for the train to make the dwell time longer at each station. In order to avoid such augmentation of delay, train dispatchers adjust train intervals by appropriately delaying the train running ahead of the delayed train. This operation is called "Train Interval Adjustment." At present, train dispatchers conduct train interval adjustment without quantitative information on passengers or definite criteria. In this paper, we propose an train interval adjustment algorithm. When compared with the present train interval adjustment without information on passengers, the proposed algorithm effectively improves the efficiency of train operation control.
