To provide a road state notification system capable of appropriately transmitting/receiving information of a fallen object.SOLUTION: A road state notification system performs: transmitting a position information request from a discovery vehicle which detects a fallen object to surrounding vehicles so as to acquire position information; considering surrounding vehicles having a distance to the fallen object being equal to or less than a threshold as a group so as to transmit a group belonging state notification from the discovery vehicle; and notifying fallen object information from the discovery vehicle being a server vehicle. In addition, the road state notification system performs: periodically requesting position information to the surrounding vehicles from the discovery vehicle so as to acquire position information of the surrounding vehicles; and when a distance between the server vehicle and the fallen object is equal to or more than the threshold, transmitting a server vehicle update request from the discovery vehicle being the server vehicle to the surrounding vehicle closest to the fallen object so as to update the server vehicle.SELECTED DRAWING: Figure 9

    【課題】落下物の情報を適切に送受信することが可能な道路状況通知システムを提供することを目的とする。【解決手段】落下物を検知した発見車両から位置情報要求を周辺車両に送信して位置情報を取得し、落下物までの距離が閾値以下の周辺車両をグループとして発見車両からグループ所属状況通知を送信し、サーバ車両の発見車両から落下物情報を通知する。また、発見車両から周辺車両に対して、定期的に位置情報を要求して周辺車両の位置情報を取得し、サーバ車両と落下物との距離が閾値以上の場合に、サーバ車両の発見車両からサーバ車両の更新要求を落下物に最も近い周辺車両に送信してサーバ車両を更新する。【選択図】図9
