Document Type and Number:
WIPO Patent Application WO/2023/127714
Kind Code:
A1
Abstract:
This railroad crossing obstacle notification system (1) comprises a railroad crossing ground device (10) that transmits notification information (30) based on detection information about a railroad crossing obstruction at a railroad crossing (5), and a relay ground device (20) disposed along a track (3) and capable of relaying the notification information (30). The railroad crossing ground device (10) associates an instruction sent to a train (40) based on the detection information and a railroad crossing ID of the railroad crossing (5), and sends these items out included with the notification information (30). The relay ground device (20) relays the received notification information (30) when the railroad crossing ID included in the received notification information (30) matches a relay-required railroad crossing ID stored as a railroad crossing that is the object of the relay in the notification information.
