CA 2395064

A process for scheduling the travel of trains on a rail corridor. The rail corridor includes a plurality of siding tracks onto which trains can be sided when a meet or pass occurs with another train on the corridor. A gradient search process is used with a cost function to determine the optimum schedule by moving each meet and pass to a siding. The individual train schedules are varied by changing train speed and/or the train departure time (i.e., the time at which the train enters the corridor).

L'invention concerne un procédé permettant de planifier le déplacement des trains dans un couloir ferroviaire. Ledit couloir ferroviaire comprend plusieurs voies d'évitement sur lesquelles on peut dévier les trains lorsqu'ils croisent ou dépassent un autre train dans le couloir ferroviaire. On utilise un procédé de recherche de gradient avec une fonction de coût afin de déterminer la planification optimum par déviation de chaque train croisant ou dépassant un autre train sur une voie d'évitement. Les planifications de train individuels varient par modification de la vitesse et/ou de l'heure de départ du train (c'est-à-dire l'heure à laquelle le train entre dans le couloir ferroviaire).
