Network-based train-following model and study of train’s delay propagation

Abstract

Based on the cellular automaton concept, this paper presents a train-following model for the moving block system with different types of trains running. We apply the model to the rail network and simulate the running of trains. We also simulate the traffic phenomenon of delay propagation in moving block system. We investigate how the main factors including train deliver time interval and initial delay affect the delay propagation of trains. The simulation results are compared with the theoretical results to verity the reliabity and feasibility of the model.
