摘要： The present disclosure provides a method and apparatus for providing an automated interlocking logic for moving-block railway signaling. According to at least one embodiment, the present disclosure provides a method for generating a train route for railway signaling based on moving block principle, including generating a directed graph for a track layout by calling pre-stored track information, generating a path matrix corresponding to the number of movement hops of a train based on the directed graph, and generating a train route from the path matrix, and verifying the train route by obtaining route information of the train from a mission of an automatic train supervision (ATS) system and comparing the route information with the train route.
