Abstract
Traffic controllers monitor train traffic in a wide control area and may actively set new targets to trains for smooth operations. A decision support system for real-time train traffic management is developed to manage timetable perturbations more effectively. This dynamic traffic control system may co-ordinate the speed of successive trains on open track (re-timing), solve expected route conflicts (re-ordering) and provide dynamic use of platform tracks or alternative paths in a corridor (local re-routing). We adopt blocking time theory for modeling track occupation and signaling constraints and alternative graphs for solving dynamic traffic control problems with the aim of increasing the punctuality at a network scale.
