Abstract
The operation of railway systems strongly depends on the underlying train control
system. ERTMS (EuropeanRail Traffic Management System) is a project launched
by the European Union in order to increase the interoperability of the national
railway systems in Europe. One of the two main components of ERTMS is GSMR,
a wireless communication standard based on GSM.
In this paper, we focus on the stochastic nature of GSM-R communication failures
and their possible impact on railway capacity. Firstly, we will compare the
results of our newly introduced model to the results obtainedwith a standard blocking
time model, applied by a couple of European railway infrastructure managers.
After this validation of our model, we will then use the stochastic approach in
order to evaluate the impact of GSM-R communication on the railway operation
and railway capacity with ETCS level 3. We can show that ETCS level 3 indeed
leads to a capacity increase in our setting. So, while a single GSM-R message may
be more error-prone than traditional communication, the framework of ETCS can
cope well with this imperfection.
Keywords: ERTMS, GSM-R, ETCS level 3, railway capacity.
1 Introduction
Railway systems know a long history of train protection and control, as to reduce
the risk of train accidents. Many systems include some automated communication
between train and trackside equipment. Several different, mostly national systems
