Abstract

The modern radio-based railway signalling systems aim to increase network capacity by enabling trains to run closer to each other. At the core of such systems is train on-board computer (discrete) responsible for computing and controlling the speed (continuous) of the train. Such systems are best captured by hybrid models, which capture discrete and continuous system aspects. Hybrid models are notoriously difficult to model and verify, in our research we address thisproblem by applying hybrid systems’ modelling patterns and stepwise refinement for developing hybrid train speed controller model.
