Abstract
When a train is delayed because of a disturbance, the time interval between successive trains increases andhigh-frequency metro lines can become unstable. Time interval control is therefore necessary in preventing such instabilities.
In this paper, we propose an optimal interval control algorithm that is easy-to-implement and that guarantees systemstability. In the proposed method, the controlled trains are determined from the time interval deviations between successivetrains; the control algorithm for staying time is designed by use of a discrete traffic model to ensure an optimal time intervalbetween successive trains. The results of a computer simulation are also given to demonstrate the validity of the proposedalgorithm.
