To provide a collision risk notification device that can avoid a collision between a moving body that is crossing a road and an approaching vehicle while preventing increase in load for communication, control, and the like due to unnecessary collision risk notifications.SOLUTION: A server (collision risk notification device), when detecting a moving body about to cross a road, identifies approaching vehicles that are approaching a crossing predicted area through which the moving body is predicted to pass within a period from a crossing start to crossing completion, on the basis of road information, moving body information including a current position and moving speed of the moving body, and vehicle information including current positions and moving speeds for vehicles that are traveling on the road. Then, the server predicts whether the approaching vehicles collide with the moving body; and controls notification so as to notify of collision risk when the approaching vehicle is predicted to collide with the moving body, meanwhile, so as not to notify of the collision risk when the approaching vehicle is predicted not to collide with the moving body.SELECTED DRAWING: Figure 1

    【課題】不要な衝突危険通知による通信や制御等の負荷の増大を回避しつつ道路を横断する移動体と接近車両との衝突を回避することができる衝突危険通知装置を提供する。【解決手段】サーバ(衝突危険通知装置)は、道路を横断しようとしている移動体を検知したとき、道路の情報と、移動体現在位置及び移動速度を含む移動体情報と、道路を走行している車両の現在位置及び移動速度を含む車両情報とに基づいて、移動体が横断開始から横断終了までに通過すると予測される横断予測エリアに接近している接近車両を特定し、接近車両が移動体に衝突するか否かを予測し、接近車両が移動体に衝突すると予測された場合は衝突の危険を通知し、接近車両が移動体に衝突しないと予測された場合は衝突の危険を通知しないように、通知を制御する。【選択図】図1
