An integrated information model for traffic planning, operation and management of railway lines

Abstract

This paper presents an integrated information model for traffic planning, operation and management of railway lines, that has been implemented in the new control centre of the Madrid-Lleida high speed line. The long and mediumterm planning information is created with an off-line Planner Tool, generating a Operational Plan in XML format. This Plan contains data needed for real-time control (as train technical scheduling and infrastructure restrictions), crew and vehicle scheduling, passengers management (as commercial scheduling, transfers), and infrastructure cost assignment to train operators. The off-line Plan is exported to the operational network, and is the unique base information of every real-time system in this network: signalling control system, passenger information system and train supervision and delay control system. In the shortterm (operation), when it is necessary to modify the Plan with the on-line Planner Tool, real-time systems are immediately notified using a MOM bus and changes are updated, so coherence of information is guaranteed. In the same way, any event generated by a real-time system is notified to the rest, sharing real-time information. Da VINCI is the product that implements this design in the high speed rail control centre of Zaragoza.
