EUROPEAN RAIL TRAFFIC MANAGEMENT SYSTEM

Objective

The ERTMS project is a unique opportunity to capitalize on the present progress of technology in areas ranging from data processing to wireless transmission to lay the foundation of a really innovative comprehensive system.

A definition of common standards will increasingly have a beneficial effect on the development of European competition and for meeting the needs of the networks. The evaluation of costs will be important in planning the implementation of the system.

The European system for the management of rail traffic which includes the system of command control of rail traffic constitutes an integrated project, in which the required results depends on the execution of the project as a whole.

For budgetary reasons, only a first phase comprising the overall design of the system, the evaluation of the location and communication tools as well as the development of the principal software components necessary for the use of the system, could be carried out under EURET.

But it is important that the remaining phases of the project, i.e. the development of the components, the implementation of the system and its prototyping could be started at a later date or in parallel according to the cases.

The Commission is now moving in this direction by developing the EUROCAB, EUROBALISE and EURORADIO projects.
A through state of the art study has been carried out in which all operational automatic train control systems (ATC) were detailed from a functional point of view. From this approach was derived a first list of 60 functions to be included in the Automatic Train Control System (ATC) of European Rail Traffic Management System (ERTMS) and a first list of interfaces related to the ATC.

The primary functions of ATC or ERTMS are defined as automatic train protection (ATP), automatic train operation (ATO), maintenance, logging, train status and operation support.

The interfaces related to the ATC are between it and train track, driver, interlocking, maintenance, passanger, supervision and environment.
Under the agreement established between the Railways and Industry, the Community of European Railways (CER) will supply the Functional Requirements Specification and the Overall System Design Specification. It is understood that the intended timetable is:
- Functional requirements available july 1992.
- Information flow analysis by june 1993.
- System design specification by august 1993.

Contents of the project:
The ERTMS project will define jointly with the CER the framework for the development of EUROCAB, EUROBALISE and EURORADIO. The ERTMS project and ETCS are long term programmes aimed at compatible long-term solutions.

First of all, within task 1, the contractor will consult the CER to obtain operational and functional requirements. This will enable the definition of needs to be established and lead to functional specifications. The criteria for the analyses of the technology are derived from these requirements. The contractor will analyse existing technology and technology currently under development within Europe and abroad.

The investigation of the location systems (task 2) and transmission methods (task 3) will lead to technical evaluation of suitable technology.

Derived from the harmonized requirements of the definition of needs, the functional specification and the technical evaluation of a number of different system concepts may be developed. The industry group will select one or more proposals and, in liaison with the railways, will establish (a) preferred solution(s).

Task 4 will require close integration with the other tasks 1, 2 and 3. The contractor proposes to define as far as possible the data processing architecture, the requirements of communication management and protocols, simulation and maintenance philosophies. Consideration will be given to the needs for unifying crossborder passenger information, train maintenance and diagnosis, and other related management tasks.
