A CONTROL STRATEGY TO PREVENT DELAY PROPAGATION IN HIGH-FREQUENCY RAILWAY SYSTEMS

Abstract

This paper proposes a railway operation control strategy that prevents delay propagation in high-frequency railway systems. We first formulate a dynamical system of a train motion that includes two types of delay propagation models: one is a passenger boarding model at each station, and the other is a train-following model in each railway section between stations. We then introduce a feedback control method to maintain scheduled operation. It is proved that the dynamical system under the proposed method is asymptotically stable at some equilibrium states.
