To obtain a traffic volume estimation device capable of accurately estimating a traffic volume based on data from a vehicle and a measurement result in an observation apparatus such as a traffic counter.SOLUTION: A traffic volume estimation device includes: a vehicle type ratio determination server 14 for calculating a vehicle type ratio which indicates a ratio of a vehicle type in an object range by image analysis of image data photographed from above the object range; an observation apparatus 30 for measuring the whole traffic volume being a traffic volume of all vehicles in the object range; an estimation traffic volume calculation server 40 for calculating an estimation traffic volume in the object range by multiplying a time-sequential change ratio of the number of vehicles in the vehicles 20 in the object range calculated based on the travel data time-sequentially acquired from the vehicles 20 communicable with an outer side by the whole traffic volume; and a vehicle type estimation traffic volume calculation server 50 for calculating a vehicle type estimation traffic volume by multiplying the estimation traffic volume by the vehicle type ratio.SELECTED DRAWING: Figure 1
【課題】車両からのデータとトラフィックカウンタ等の観測機器での計測結果とに基づいて交通量を精度よく推定可能な交通量推定装置を得る。【解決手段】対象範囲を上空から撮像した画像データの画像解析により、対象範囲における車両の種別の比率を示す車両種別比率を算出する車両種別比率判定用サーバ14と、対象範囲の全車両の交通量である全体交通量を計測する観測機器30と、外界との通信が可能な車両20から時系列で取得した走行データに基づいて算出した対象範囲における車両20の時系列での台数の変化率を、全体交通量に乗算して対象範囲における推定交通量を算出する推定交通量計算用サーバ40と、推定交通量に車両種別比率を乗算して車両種別推定交通量を算出する車両種別推定交通量計算用サーバ50と、を含む。【選択図】図1
