摘要： A device for monitoring the passage of a train traveling through a rail way crossing, said device including a first and second sensors for sensing the presence of the train on a rail track when the train is in proximity to the sensors, said first and second sensors positioned adjacent the track, first and second processors opperatively coupled to the first and second sensors, respectively, the processors adapted to monitor the sensors and determine the speed and direction of the train when the train passes the sensors. The device also includes a signal positioned adjacent the crossing for signaling the public that a train is about to enter the rail way crossing, and a third processor operatively coupled to the signal and operatively coupled to the first and second processors, the third processor adapted to activate the signal when the train is within a predetermined time interval from entering the crossing.
