  • Patent number: 8967553
    Abstract: In accordance with a predetermined segment definition rule based on a point-switch protection section, a point switch control direction, and a train advancing direction, a plurality of segments are defined in advance with respect to a railway network. Segment competition information in which a competitive relationship between the plurality of segments is set in advance is prepared. A segment use permission setting part determines whether or not a competition for a use-requested segment in terms of a train operation occurs between the plurality of trains, by using segment competition information and segment use permission status information. A use-requested segment for which it is determined that no competition occurs is incorporated, as a use permission segment, into use permission segment information of the corresponding train. In accordance with a result of the competition determination, the segment use permission status information is updated.

  • Patent number: 8774992
    Abstract: A next station state estimating unit estimates a preceding train position from information about a stop track circuit of a current train and from a signal aspect table. It estimates the time, at which the preceding train exits the next station and brake pattern before the station is canceled, from information about the preceding train position, from information about the occupied track circuit on which the current train is present and related information between track circuits and a station and information about occupied duration of the station, which are retained in a track database, and from a history of the preceding train position retained in a history retaining unit. The time estimated is sent to a driver's cab by a communication unit.
