The Wayside Horn system (WHS) is a critical traffic control device. Typically used in a quiet zone, the wayside horn system warns motorists by projecting sound down the roadway instead of down the track. The wayside supplements the audible warning provided by the train horn and is more effective in alerting motorists who may have their vehicle windows up, the entertainment system operating, or are distracted by their cell phone or smartphone.
