Object Oriented developments :









SLTC (Société Lyonnaise de Transports en Commun, a daughter company of the VIA GTI Group) is the urban PT operator of the Greater Lyon area. It uses an information system on operations integrating several software applications. Starting from the need to re-engineer some of these applications, the project brought in TITAN is aimed at renewing the whole information system, by creating a relational data base on operations, linked to all concerned applications and using the Transmodel recommendations.

The data base will be fed by vehicle scheduling, driver scheduling and stop point management applications. The data used in operations will be activated by a module for management of the operational calendar. The interfaces with down stream sub-systems will be designed and implemented. This includes applications for printed display/leaflets on timetables, dynamic and passive displays in major stop areas, telephone and telematics (Minitel) information systems, vehicle monitoring system, management information system, driver rostering and personnel disposition.

The computer policy has been oriented towards the implementation of a database using the Oracle RDBMS, distributed in a client/server architecture to user terminals based on the MS-Windows standard. Some terminals will be organized ('info-centres') to allow a powerful and user-friendly access to the data and, therefore, to provide new functional possibilities, especially as regards the management information.

The verification stage will consist in a lab running of the system on a limited set of data and equipment (corresponding to the simulated operations on part of 3 lines), while the demonstration will involve a real implementation of the system in the company.







The Régie Autonome des Transports Parisiens (RATP) is the main PT operator of the Paris region, one of the largest in Europe. RATP is strongly involved in developments based on object-oriented techniques. The object-oriented approach is likely to become in the years to come the reference technology for data base design in complex domains. A main advantage of this method is to facilitate the link between the analysis and the specification of complex real systems, and the design and the implementation of information systems. RATP is therefore in charge of the study aiming at the development of an object-oriented model, taking Transmodel into account, as regards the data structure. Other contributions will have to be taken into account, such as the contribution of the University of Brunel that developed an object-oriented model based on Transmodel, within the ESPRIT project superbus. RATP will contribute as well to introduce extensions and enhancements to Transmodel V.4, as regards the real-time control domain.

As mentioned above, several developments are already carried out by RATP using object-oriented modelling techniques. For, instance, the development of a training tool for the staff in charge of controlling the surface network (“ Spartacus ”) is in the process to achieved. In future, it is planned to adapt and extend “ Spartacus ” to comply with the developments achieved within TITAN.
