Abstract
The present invention relates to a warning system for displaying a warning message to a vehicle approaching a railroad crossing. The railroad crossing includes a railroad along which a train can travel, and a road crossing the railroad and along which the vehicle can travel. The warning system includes an identification system for identifying at least one identity characteristic (e.g. number plate, vehicle type, etc.) relating to the vehicle. A train detection system detects at least one train characteristic (e.g. presence, position, speed) relating to the train approaching the railroad crossing along the railroad. A vehicle detection system detects at least one vehicle characteristic (e.g. presence, position, speed) relating to the vehicle approaching the railroad crossing along the road. The warning system further includes a display system for displaying the warning message to the vehicle responsive to detecting both the train and vehicle characteristics.
