    摘要： A system for railroad directive management is presented. The system can receive a myriad of data related to a directive, track segments, and/or vehicle events on the track and/or track segments. Vehicle- and/or event-specific data can be compared with one or more thresholds, including force thresholds, temporal thresholds, environmental thresholds, and/or event thresholds to determine whether and what kind of directive modification should be instantiated. Specialized algorithms can be implemented to trace vehicle paths along the track to determine whether directive-related segments are traversed, and specialized clustering algorithms can be utilized to cluster data unique to a particular segment on a per-segment basis. The system can be integrated with existing track infrastructure and can further generate alerts to notify coupled systems and/or personnel of directives and/or modification thereof.

    摘要： A method and an apparatus for a train control installation are disclosed, and are based on the absolute permissive block concept. The train control installation employs a plurality of generic absolute block signal units (ABSU), wherein each signal unit includes means for detecting the crossing of a train passed a discrete point, means for exchanging data with adjacent ABSUs, means for generating and communicating a movement authority limit to a train, means for generating and displaying a signal indication, and means for enforcing a stop aspect. The train control installation can be used in conjunction with a communication based train control (CBTC) system to provide a degraded mode of operation without impacting the availability and the reliability of the CBTC system. Further, the train control installation has a self-healing feature to maintain train service during an ABSU failure.

    摘要： To provide a wireless train control system that can perform a stable operation. The wireless train control system controls a wireless-control compliant train following a wireless-control noncompliant train by a ground control device. A stop limit point of the wireless-control compliant train is set by a track circuit in which a tail end position of the wireless-control noncompliant train is present. By using a track-circuit state signal indicating that the track circuit is turned on or turned off and a time-element-added track-circuit state signal indicating turn-off at a timing delayed by a set time after the track-circuit state signal has indicated turn-off, when the track-circuit state signal indicates turn-off and the time-element-added track-circuit state signal indicates turn-on, it is determined that turn-off indicated by the track-circuit state signal is caused by the wireless-control compliant train that is a train itself being present, and the stop limit point is not updated.
