To provide a traffic facility visibility determination device and a traffic facility visibility determination program with which it is possible to determine the visibility of a traffic facility that a vehicle drive should visually recognize while driving, by a simple process with good accuracy.SOLUTION: A traffic facility visibility determination device comprises a traffic facility information acquisition unit, a three-dimensional map information acquisition unit, and a visibility determination unit. The traffic facility information acquisition unit acquires the position information of a prescribed traffic facility. The three-dimensional map information acquisition unit acquires three-dimensional map information that indicates the shape and position information of an object existing in an area that includes the traffic facility and a first determination target section that is the travel section of a vehicle in which the visibility of the traffic facility is to be determined. The visibility determination unit determines, for each vehicle position that the vehicle in the first determination target section could take, whether or not there exists any object in the first determination target area that is identified on the basis of a straight line from the viewpoint position of the vehicle driver to the traffic facility, and determines that the vehicle position where it is determined that there exists any object is a position where the traffic facility visibility is low.SELECTED DRAWING: Figure 2

    【課題】車両の運転手が運転中に視認すべき交通設備の視認性を簡易な処理で精度良く判定することが可能な、交通設備の視認性判定装置および交通設備の視認性判定プログラムを提供する。【解決手段】交通設備の視認性判定装置は、交通設備情報取得部と3次元地図情報取得部と視認性判定部とを備える。交通設備情報取得部は、所定の交通設備の位置情報を取得する。3次元地図情報取得部は、交通設備および交通設備の視認性の判定対象とする車両の走行区間である第1判定対象区間を含むエリア内にある物体の形状情報および位置情報を示す3次元地図情報を取得する。視認性判定部は、第1判定対象区間内の車両が取り得る車両位置ごとに、車両の運転手の視点の位置から交通設備までの直線に基づいて特定される第1判定対象エリア内にいずれかの物体があるか否かを判定し、いずれかの物体があると判定した車両位置を、交通設備の視認性が低い位置と判定する。【選択図】図2
