PROBLEM TO BE SOLVED: To improve the detection accuracy of road surface deterioration.SOLUTION: An road surface inspection device 10 acquires a deterioration candidate position at which a deterioration candidate of a road surface is detected by a process of detecting an abnormality on the road surface of a road. The road surface inspection device 10 calculates a frequency at which an acceleration outside an allowable range is measured at the deterioration candidate position by referring to an acceleration at a measurement position corresponding to the deterioration candidate position among the accelerations stored in a driving data storage in which the acceleration measured in a direction parallel to the road surface on which a vehicle drives by an acceleration sensor mounted on the vehicle and the measurement position at which the acceleration is measured are stored in association with each other. The road surface inspection device 10 determines, when the calculated frequency is equal to or greater than a predetermined threshold value, that the deterioration candidate position at which the frequency is calculated is a position at which the road surface is deteriorated. |
