To provide a route planning device and route planning method for setting an appropriate route plan by avoiding an obstacle such as another ship.SOLUTION: A route planning device comprises: a planned route acquisition part for receiving a planned route representing a route and a direction of a water mobile body from a current location of the water mobile body; a mobile body information acquisition part for receiving mobile body information including any one or more of information of a location, a route direction, and a speed of the mobile body; an obstacle information acquisition part for receiving obstacle information including any one or more of information of a location, a moving direction, and a speed of an obstacle; a collision risk value calculation part for determining a collision risk value associated with the planned route along the route direction based on the mobile body information and the obstacle information; and a collision risk evaluation part for determining whether to avoid the planned route or to continue navigation on the planned route based on the collision risk value associated with the planned route.SELECTED DRAWING: Figure 1

    【課題】 他船などの障害物を回避し適切な航路計画を設定する航路計画装置及び航路計画方法を提供する。【解決手段】 航路計画装置は、水上移動体の現在位置から前記水上移動体の航路と方向を示す計画航路を受信する計画航路取得部と、移動体の位置、航路方向および速度に関する情報のうちいずれか一つ又は二つ以上の情報を含む移動体情報を受信する移動体情報取得部と、障害物の位置、移動方向及び速度に関する情報のうちいずれか一つ又は二つ以上の情報を含む障害物情報を受信する障害物情報取得部と、移動体情報と障害物情報とに基づいて航路方向に沿った計画航路に関連付けられた衝突リスク値を決定する衝突リスク値算出部と、水上移動体が計画航路に関連付けられた前記衝突リスク値に基づいて計画航路から回避すべきか計画航路上の航行を継続するかを判断する衝突リスク評価部とを備える。【選択図】図1
