PROBLEM TO BE SOLVED: To provide a device that can estimate a traffic volume of a target route with higher accuracy by taking into consideration traffic conditions on each route in a region range.SOLUTION: A device of the present invention comprises: OD generating means for generating an information O of a position range of a movement start and an information D of a position range of a movement end from a communication history; OD position range determination means for determining an O position range of the information O and a D position range of the information D from the O position range through the target route obtained from a communication position information log group passing through the position range group including the target route; usage rate storing means for storing an usage rate of the target route of a passing object passing through the position range in association with each other, for each position range in the O and D position ranges; and traffic volume determining means for calculating the number of the passing object passing through the target route in the group on the basis of a total number of terminals in the communication position information log group corresponding to the group for each pair of O and D position ranges and the usage ratio corresponding to the position range of the group and determining the traffic volume of the target route from the calculated number of each pair of passing objects.SELECTED DRAWING: Figure 2 【課題】地域範囲における各経路での通行状況も勘案した上で、対象経路の通行量をより高い精度で推定可能な装置を提供する。【解決手段】本装置は、通信履歴から、移動開始の位置範囲の情報Ｏ、及び移動終了の位置範囲の情報Ｄを生成するＯＤ生成手段と、対象経路を含む位置範囲群内を通る通信位置情報ログ群から、情報ＯのＯ位置範囲、及びこのＯ位置範囲から対象経路を通って至る情報ＤのＤ位置範囲を決定するＯＤ位置範囲決定手段と、Ｏ及びＤ位置範囲の各位置範囲について、位置範囲を通る通行体の対象経路の使用割合を対応付けて保存する使用割合保存手段と、Ｏ及びＤ位置範囲の組毎に、当該組に相当する通信位置情報ログ群に係る端末の集計数と、当該組の位置範囲に対応付けられた使用割合に基づいて、対象経路を通行した通行体の当該組での数を算出し、算出された通行体の当該組毎の数から対象経路における通行量を決定する通行量決定手段とを有する。【選択図】図２
