Development of Deer Deterrent Equipment for Mitigation of Deer-Train Collisions

抄録

Deer-train collisions have become a serious problem in Japan. To mitigate these collisions, we have composed a deterrent sound which consists of a deer alarm call and fierce barking of a dog. It has been observed that broadcasting the deterrent sound from a train to ward off deer resulted in a 30% increase in the frequency of deer running away from the tracks. We also developed equipment to enable automatic broadcasting of the deterrent sound from trains when they are in designated sections where collisions happen frequently.
