To provide a traffic flow prediction device, traffic flow prediction method, and program for minutely predicting a traffic flow.SOLUTION: A traffic flow prediction device comprises: a detector information acquisition section for acquiring detector information, from vehicle detectors, which is acquired at predetermined time interval by the vehicle detectors respectively arranged at multiple points on a road and which includes at least vehicle number information on vehicles passing the points where the vehicle detectors are arranged and speeds of the vehicles; an on-vehicle unit information acquisition section for acquiring on-vehicle unit information which includes at least position information on vehicles traveling on the road and speeds of the vehicles traveling on the road from on-vehicle units mounted on the vehicles traveling on the road; and a traffic flow prediction section for predicting a traffic flow on the road based on a relational expression between a traffic density and speeds and relation between a traffic density and a traffic density at a succeeding time, that are learned based on the detector information and the on-vehicle unit information.SELECTED DRAWING: Figure 1

    【課題】本発明は、より詳細な交通流の予測を可能とする、交通流予測装置、交通流予測方法及びプログラムを提供する。【解決手段】本発明に係る交通流予測装置は、道路の複数の地点のそれぞれに設置された車両検知器によって、所定の時間間隔で取得され、前記車両検知器が設置された地点を通過する車両の台数情報と、前記車両の速度と、を少なくとも含む検知器情報を、前記車両検知器から取得する検知器情報取得部と、前記道路を走行する車両に載せられた車載器から、前記道路を走行する車両の位置情報と、前記道路を走行する車両の速度とを少なくとも含む車載器情報を取得する車載器情報取得部と、前記検知器情報及び前記車載器情報に基づいて学習された、交通密度と速度との関係式、及び交通密度と次時刻の交通密度との関係に基づいて、前記道路における交通流を予測する交通流予測部と、を備える。【選択図】図1
