Abstract

Le réseau ferroviaire est imagé par sélection et disposition d'objets individuels (EO1 à EO9) selon la topologie des voies. Les objets individuels (EO1 à EO9) peuvent être sélectionnés dans une réserve d'objets individuels standardisés et chacun représente un élément de ligne (SEL, SELS) avec ses points de connexion sous forme de n÷uds. Les n÷uds correspondants d'objets individuels adjacents sont associés à chaque n÷ud (ANK) d'un objet individuel sélectionné. Conformément à un mouvement de véhicule à simuler, des objets individuels situés sur la trajectoire du véhicule sont caractérisés successivement comme occupés ou à nouveau libres. Des données (DAT) décrivant les situations dynamiques sont préparées sous une forme qui peut être traitée par un centre de contrôle d'ordre supérieur (LS).
