Abstract

In this paper, we compare the transportation performance of a given railway for three types of signaling system: fixed-block signaling, moving-block signaling and train-convoy signaling. The transportation performance is evaluated from two aspects: track capacity and robustness to delays. The transportation performance is computed using numerical method and a new cellular automaton model is proposed to simulate the behavior of a train. The simulation results show that train-convoy signaling can improve track capacity and robustness to delays, at the same time, compared to fixed-block signaling and moving-block signaling.
