Modelling and Simulation of ERTMS for Current and Future Mobile Technologies

Nowadays, train control in-lab simulation tools play a crucial role in reducing extensive and expensive on-site railway testing activities. In this paper, the authors present their contribution in this arena by detailing the internals of their European Railway Train Management System in-lab demonstrator. This demonstrator is built over a general-purpose simulation framework, Riverbed Modeler, previously Opnet Modeler. The authors' framework models both European Rail Traffic Management System (ERTMS) subsystems, the Automatic Train Protection application layer based on movement authority message exchange and the telecommunication subsystem based on Global System for Mobile Communications - Railway (GSM-R) communication technology. The authors provide detailed information on their modelling strategy. The authors also validate their simulation framework with real trace data. To conclude, under current industry migration scenario from GSM-R legacy obsolescence to IP-based heterogeneous technologies, the authors' simulation framework represents a singular tool to railway operators. As an example, they present the assessment of related performance indicators for a specific railway network using a candidate replacement technology, long-term evolution (LTE), versus current legacy technology. To the best of the authors' knowledge, there is no similar initiative able to measure the impact of the telecommunication subsystem in the railway network availability.
