EUROPE-TRIS

European Railways Optimisation Planning Environment - Teleconferencing Railways Information System

EUROPE - TRIS is based on three core sub-systems: TCM, TTC and F-TTM. Each of these addresses a specific stage in the timetable planning workflow, and is described as follows:

TCM - Traffic Capacity Management

TCM is a telematics approach to the management of access-to-infrastructure, i.e. between the track provider and train operating companies. It specifically implements EU Directive 95/19 and follow-on principles. Transport companies submit requests for track access (i.e. train scheduling on a yearly/ seasonal basis), and the infrastructure manager responds within a specific timeframe respecting certain rules. TCM is based on a server/client architecture and uses advanced train scheduling algorithms.

TTC - Timetable TeleConferencing
TTC provides a video-conferencing environment that allows rail planners, in different countries or national network sites, to co-operate interactively and reach agreements for validating the train schedules. The TTC concept works downstream from TCM and addresses the intermediate and final stages of train scheduling. It has the facility to interface with national computer-aided timetable design systems, to improve the traditional process by achieving standardisation and inter-operability in tactical planning. The application is sponsored by the Infrastructure Commission of the UIC (Union Internationale Chemins de Fer) within their framework of Timetable Harmonisation, in which several rail companies participate.

F-TTM - Freight Timetable TeleMarketing
F-TTM supports contingency planning i.e. scheduling trains at short notice. This involves links with transport companies, finding slots for special trains, information exchange, agreements and co-operative decision making between trans-border traffic coordinators.
