Cellular automaton model for moving-like block system and study of train's delay propagation

Based on the NaSch traffic model, we propose a cellular automaton traffic model for moving-like block system to simulate the railway traffic. We simulate the traffic phenomenon of delay propagation. We also investigate how the main facts including the length of location unit, train time interval and initial delay affect the delay propagation of trains.
