<P>PROBLEM TO BE SOLVED: To provide a train approach-alarming system that prevents the reliability of the system from being degraded due to the failure to give an alarm against, for example, a train that does not travel in an work area for a turnaround at the station next to the work area and which prevents the attention-seeking ability of a worker from being weakened while eliminating the need for waiting for a train that will not pass through the work area. <P>SOLUTION: The system determines that the train passes through the work area, by using a state of a local traffic light and a departure order or a block order, thereby preventing a wasteful alarm and preventing the attention-seeking ability from being weakened. <P>COPYRIGHT: (C)2012,JPO&INPIT |
