摘要： An automated railroad crossing warning system includes a controller for servicing the intersection of a railroad track and a roadway with directional horns oriented in opposite directions to direct horn blasts along the roadway is disclosed. A controller detects the presence of a train approaching the intersection and transmits a signal to the horns to activate the horns. A horn detector transmits a signal to the controller upon activation of the horns at a predetermined decibel level. The controller then activates the light such that the railroad engineer can visually determine that the horns at the intersection are being activated. The controller includes an electronic circuit which causes the horns to produce blasts in a predetermined sequence which matches the conventional signal produced by a train engine upon approaching such a crossing.
