To correctly obtain a traffic state in real time in a traffic state prediction device.SOLUTION: A collection data characteristic table stores tabulation unit information for each mobile body, which indicates whether position information collection data which has been input to a traffic state prediction device is tabulation data or individual data. An individual observation information estimation section determines whether position information collection data is tabulation data or individual data based on tabulation unit information, and replaces tabulation data with individual data when position information collection data is tabulation data as a determination result, so as to generate individual observation information for each mobile body. An individual position prediction section predicts a position of a mobile body at a prediction object time based on individual observation information, so as to output an individual position prediction result.SELECTED DRAWING: Figure 1

    【課題】交通状況予測装置において、交通状況をリアルタイムかつより正確に把握する。【解決手段】収集データ特性テーブルは、交通状況予測装置に入力された位置情報収集データが集計データか個体データかを示す集計単位情報を移動体ごとに格納し、個体観測情報推計部は、集計単位情報に基づいて位置情報収集データが集計データか個体データかを判定し、判定の結果、位置情報収集データが集計データの場合、集計データを個体データに置換して移動体毎に個体観測情報を生成し、個体位置予測部は、個体観測情報に基づいて予測対象時刻における移動体の位置を予測して個体位置予測結果を出力する。【選択図】図1
