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.
