Abstract

The European Railway Traffic Management System (ERTMS) has introduced a significant enhancement in the operation of the railway network, in terms of robustness and efficiency. A main characteristic of the ERTMS is the adoption of the Global System for Mobile Communication for Railway (GSM-R) as the method of train-to-ground communication. As the operation of the signalling system in ERTMS requires a reliable and seamless GSM-R connection, the site planning for the GSM-R data communication system is a critical task in the development of the ERTMS railway network. In this thesis, a mathematical GSM-R modelling methodology is proposed for formulating and solving the site planning problem for GSM-R Base Transceiver Stations (BTSs), which is aimed at providing reliable GSM-R coverage for a railway network, while reducing the construction and operation cost of the infrastructure. Optimisation algorithms are also proposed in this thesis for solving the GSM-R BTS site planning problem. In addition, an integrated simulation platform has been developed for simulating and validating the GSM-R communication system in the railway simulation environment. The result shows that the optimal result generated by the proposed methodology can provide identical reliability as that of the BTS site plan of an existing ERTMS railway network. The author of this thesis thus provides a methodology that can reduce the effort involved in BTS site surveys, when planning a GSM-R network. Mathematical optimisation and simulation validation can reduce the time required for the BTS site planning process.
