Abstract (en)
[origin: US6827315B2] The invention relates to a decision procedure in combinational logic which requires a computing time of n for determining the congestion of a railway track system. The railway track system supports n trains, each with a route length of m itineraries. Prior to setting a requested route segment for a given train, a query is performed to check train positions and whether the given train is allowed to travel on the track sectors to be used for the requested route segment, without causing a possibility that the track system may become congested. The processing steps can be reduced. a) verification of whether a train can reach the next immediate track sector of a route; b) verification for a two-train variation whether a reference position of the first train prevents the second train from traveling on its route; c) new dependencies are created using transitivity and for combinations of two trains, a verification is made whether a cogent sequence exists. Step c) is iterated until no new dependencies occur or no train can reach its destination.
