PROBLEM TO BE SOLVED: To provide an analysis device, an analysis method, and an analysis program capable of accurately grasping the influences to the traffic lane by the passage of the pedestrian crossing.SOLUTION: An analysis device includes: an acquisition part for acquiring prove data including a position of a vehicle; and an estimation part for performing an estimation of an object lane that forms a crossing point. The estimation part measures a movement distance in a travel state in which the vehicle transits from a stop state to a travel state in the object lane and transits to the stop state again in a period in which a light color of the signal light corresponding to the object lane is a predetermined color based on the prove data, and performs the estimation based on the measured movement distance. The estimation part performs the estimation that the object lane is a lane having a large degree of influences of the passage of the pedestrian crossing based on the size relationship between the measured movement distance and the length of a route from the predetermined position in the object lane to the pedestrian crossing provided on the left turn of the crossing point.SELECTED DRAWING: Figure 2
【課題】横断歩道の通行による車線への影響を的確に把握することが可能な分析装置、分析方法および分析プログラムを提供する。【解決手段】分析装置は、車両の位置を含むプローブデータを取得する取得部と、交差点を形成する対象車線の評価を行う評価部とを備え、前記評価部は、前記プローブデータに基づいて、対象車線に対応する信号灯器の灯色が所定の色となった期間において、前記対象車線において停止状態から走行状態へ遷移し、再び前記停止状態へ遷移した車両の前記走行状態における移動距離を計測し、計測した前記移動距離に基づいて前記評価を行い、前記評価部は、計測した前記移動距離と、前記対象車線における所定位置から前記交差点の左折先に設けられた横断歩道までの経路の長さとの大小関係に基づいて、前記対象車線が前記横断歩道の通行の影響度合いの大きい車線であることに関する前記評価を行う。【選択図】図2
