ROAD DETERIORATION DETERMINATION SYSTEM
To provide a technique for quickly determining that the surface roughness of a road has deteriorated.SOLUTION: A road deterioration determination system includes a first vibration sensor located in a first section of a first road and a second vibration sensor located in a second section adjacent to the first section. A first equivalent range is generated by using measured values measured multiple times by the first vibration sensor in the same period when the surface roughness of the first road is equivalent to that immediately after the first road is created. A second equivalent range is generated by using measured values measured multiple times by the second vibration sensor in the same period. The surface roughness of the first section is determined to be degraded more than that immediately after the first road was created when a first number of times per unit of time for which the first measurement is determined not to be within the first equivalent range is only a prescribed number of times greater than the second number of times per unit of time for which the second measurement is determined not to be within the second equivalent range.SELECTED DRAWING: Figure 1
【課題】道路の表面粗さが劣化したことを素早く判断するための技術を提供する。【解決手段】道路劣化判断システムは、第１道路の第１区間に配置されている第１振動センサと第１区間に隣接する第２区間に配置されている第２振動センサを備え、第１道路の表面粗さが第１道路の生成直後と同等である同等期間において第１振動センサによって複数回にわたって計測される計測値を利用して、第１同等範囲を生成し、同等期間において第２振動センサによって複数回にわたって計測される計測値を利用して、第２同等範囲を生成し、第１計測値が第１同等範囲に含まれないと判断された単位時間当たりの第１回数が、第２計測値が第２同等範囲に含まれないと判断された単位時間当たりの第２回数よりも所定倍だけが大きい場合に、第１区間の表面粗さが第１道路の生成直後よりも劣化していると判断する。【選択図】図１
