ABSTRACT:
A system and method for a directional audio train signaling system that comprises a receiver for receiving a signal indicating the approach of a train to a point of interest and one or more directional audio transmitter systems for transmitting a warning related to the approach of a train. A plurality of directional audio transmitters may be used, each with a footprint covering a portion of a roadway approaching an intersection. The receiver may be associated with an acknowledgement transmitter such that a train system confirms receipt of the alarm signal at the receiver.
