Abstract To provide an information management device capable of reducing processing load and communication traffic for vehicle information acquired at individual vehicles.SOLUTION: An information analysis unit monitors a data volume of collected vehicle information per area. Depending on the data volume of the collected vehicle information and for each area, the information analysis unit determines whether an uploading condition for the vehicle information is to be maintained without changing the uploading condition (step S2), whether the data volume of the vehicle information is to be reduced by reducing the number of samplings (step S4), or whether the data volume of the vehicle information is to be substantially reduced by stopping uploading (step S7).SELECTED DRAWING: Figure 5 【課題】各車両において取得される車両情報の処理負荷及び通信トラフィックを軽減することが可能な情報管理装置を提供する。【解決手段】情報解析部は、収集された車両情報のデータ量をエリア単位で監視する。情報解析部は、エリアごとに、収集した車両情報のデータ量に応じて、車両情報のアップロード条件を変更することなく維持するか(ステップS2)、サンプリング回数を減らして車両情報のデータ量を低減するか(ステップS4)、またはアップロードを停止して車両情報のデータ量を大幅に低減するか(ステップS7)を決定する。【選択図】図5
