CALCULATION DEVICE, CALCULATION METHOD AND PROGRAM
To finely grasp a road surface state at each position.SOLUTION: A calculation device includes: a road surface information acquisition part that acquires a road surface height information indicating a height position in a vertical direction of a road surface of a road R for each road surface position on the road R; an IRI calculation part, which calculates IRI in a first section S1 of a unit distance on the road R and IRI in a second section S2 of length exceeding the unit distance and less than twice the unit distance based on the road surface height information for each road surface position; and a road surface state calculation part, which calculates IRI at a non-overlapping section S3 that does not overlap the first section S1 in the second section S2 based on IRI in the first section S1 and IRI in the second section S2.SELECTED DRAWING: Figure 5
【課題】位置毎の路面状態を細かく把握する。【解決手段】演算装置は、道路Ｒの路面の鉛直方向における高さ位置を示す路面高さ情報を、道路Ｒ上の路面位置毎に取得する路面情報取得部と、路面位置毎の路面高さ情報に基づいて、道路Ｒ上の単位距離の第１区間Ｓ１におけるＩＲＩと、単位距離を超えて単位距離の２倍未満の長さの第２区間Ｓ２におけるＩＲＩとを算出するＩＲＩ算出部と、第１区間Ｓ１におけるＩＲＩと第２区間Ｓ２におけるＩＲＩとに基づいて、第２区間Ｓ２において第１区間Ｓ１と重ならない非重複区間Ｓ３におけるＩＲＩを算出する路面状態算出部と、を含む。【選択図】図５
