PROBLEM TO BE SOLVED: To minimize reduction of versatility about estimation of a meandering point.SOLUTION: A server device 10 receives designation of travel recording and position recording subjected to sensing in a vehicle. For each first section partitioned at intervals in which a position is recorded in the position recording, the server device 10, having a boundary at a position that satisfies a given condition about the first section among positions recorded in position recording different from the position recording designation of which is received, divides the first section into a plurality of second sections. On the basis of time change of velocity corresponding to the second section among velocities included in the travel recording designation of which is received and the travel distance within the second section, the server device 10 estimates a meandering point included in at least one second section among the plurality of second sections.SELECTED DRAWING: Figure 2

    【課題】曲折点の推定に関する汎用性が低下するのを抑制すること。【解決手段】サーバ装置10は、車両でセンシングされた走行記録及び位置記録の指定を受け付ける。サーバ装置10は、位置記録の位置が記録される間隔で区切られた第1の区間ごとに、指定を受け付けた位置記録と異なる他の位置記録に記録された位置のうち第1の区間に関する所定の条件を満たす位置を境界に、第1の区間を複数の第2の区間へ分割する。サーバ装置10は、指定を受け付けた走行記録に含まれる速度のうち第2の区間に対応する速度の時間変化と、第2の区間内の走行距離とから、複数の第2の区間のうち少なくとも1つの第2の区間に含まれる曲折点を推定する。【選択図】図2
