To provide a human flow estimating device that makes it possible to set even an open space as a target area for human flow estimation, and performs highly accurate human flow estimation based on measurement data from a plurality of human flow measurement devices having different measurement characteristics.SOLUTION: In the human flow estimating system, the human flow estimating device 10 includes: an analysis unit 107 for acquiring a number of passes and traveling directions of pedestrians from two or more kinds of human flow measurement devices having different measurement characteristics, generating, as hypothesis OD data, plural pieces of OD data, which is a number of pedestrians heading from an actual entrance to an exit or a number of pedestrians heading from a virtual entrance to a virtual exit, and performing human flow analysis; a data assimilation OD estimation unit 108 for integrating the number of passes and the traveling directions of the pedestrians acquired from the human flow measurement devices with the data obtained from the analysis unit based on an allowable measurement error determined on the basis of the human flow measurement devices to generate estimated OD data; and a display control unit 110 for displaying the estimated OD data obtained from the data assimilation OD estimation unit 108 on a display unit 13 as a human flow estimation result.SELECTED DRAWING: Figure 1
【課題】開放空間であっても人流推定の対象領域とすることを可能とし、測定特性が異なる複数の人流計測装置からの計測データに基づき高精度な人流推定装置を提供する。【解決手段】人流推定システムにおいて、人流推定装置10は、異なる測定特性を有する2種以上の人流測定装置から通過人数及び歩行者の進行方向を取得し、実在する入口から出口へと向かう歩行者の人数又は設定される仮想の入口から仮想の出口へと向かう歩行者の人数であるODデータを仮説ODデータとして複数生成し人流解析を行う解析部107と、人流測定装置に基づき決定される許容測定誤差に基づき人流測定装置から取得される通過人数及び歩行者の進行方向と解析部から得られたデータを統合し推定ODデータを生成するデータ同化OD推定部108と、データ同化OD推定部108から得られた推定ODデータを人流推定結果として表示部13に表示する表示制御部110とを有する。【選択図】図1
