Abstract

Traditional railway planning and control is based on a tactical design of a conflict-free timetable including detailed infrastructure utilization and rolling stock circulations. Operational traffic control is mainly aimed at adherence to the timetable. Operational traffic management is reactive: a train driver responds to the signalling system, and dispatchers and traffic controllers only adjust the plan when trains are highly delayed. Many secondary delays can however be prevented if traffic is proactively managed. Based on an accurate monitoring of actual train positions potential conflicting routes can be predicted in advance and resolved in real-time. The adjusted targets (location-time-speed) are then communicated to the relevant trains by which the informed drivers are able to anticipate on the changed traffic circumstances and adjust the train speed accordingly.
