Railway Traffic Management of the Future
When incidents or delays occur during train operating, quick decisions have to be taken to limit the consequences of this situation and to avoid snow-ball effects. This problem is complex due to the limited efficiency of local decisions and the quasi-necessity to build a global view of the potential consequences before choosing the best solution. IT tools based on optimisation algorithms have to be developed or improved to propose efficient decisions as soon as possible Two main actors are involved in the delay resolution: the infrastructure manager (responsible for traffic management) and the railway undertaking (in charge of resources like rolling stock and drivers). When incidents occur (other than small delay s), the best solution cannot be found without interactive communication between infrastructure manager and railway undertaking. So, despite their different missions, both actors have to develop decision-making tools. This is particularly crucial for the railway undertaking, which without efficient tools will undergo passively the decisions of the infrastructure manager After a short description of the processes applied by IIVI and Rl,the paper presents a global project developed in France to improve train operating and rescheduling and describes the foreseen optimisation and communication tools.
