RAILWAY DYNAMIC TRAFFIC MANAGEMENT: APPLICATION OF A TRAIN RESCHEDULING SYSTEM REDUCING DELAYS

The paper applies principles of dynamic traffic management to solve the train re-scheduling problem faced by railway infrastructure managers during operations. When train operations are perturbed conflicts arise with respect to the scheduled train paths. A detailed mathematical formulation and dispatching algorithms are adopted to re-compute a new timetable of feasible arrival and departure times. The system generates a conflict free schedule with admissible train dynamics and with observance of minimum safety headway distances. Computational experiments on a part of the Dutch rail network show that the adopted rescheduling support system provides better solutions when compared to simple dispatching rules.
