PROBLEM TO BE SOLVED: To provide an avoidance behavior determination program, avoidance behavior determination method and avoidance behavior determination device that can highly accurately detect an avoidance behavior.SOLUTION: An avoidance behavior determination program is configured to make a computer execute processing of: calculating an approach angle of a wake of a specific ship, and exit angle thereof as to each of a plurality of grids through which the wake thereof passes; extracting the grid in which the approach angle and exit angle comply with a determination condition set to each of the plurality of grids on the basis of the determination condition; and determining whether the specific ship takes an avoidance behavior on the basis of a relative distance with respect to other ship and corresponding to a location of the specific ship in its wake in the extracted grid.SELECTED DRAWING: Figure 12
【課題】回避行動を精度良く検出できる回避行動判定プログラム、回避行動判定方法および回避行動判定装置を提供する。【解決手段】回避行動判定プログラムは、コンピュータに、特定の船舶の航跡が通過する複数のグリッドそれぞれについて、航跡の進入角および退出角をそれぞれ算出する処理を実行させる。回避行動判定プログラムは、コンピュータに、複数のグリッドそれぞれについて設定された判定条件に基づき、進入角および退出角が、判定条件に適合するグリッドを抽出する処理を実行させる。回避行動判定プログラムは、コンピュータに、抽出されたグリッドにおける航跡での特定の船舶の位置に対応した、他の船舶との相対距離に基づき、特定の船舶が回避行動を行ったか否かを判定する処理を実行させる。【選択図】図12
