Original Abstract Submitted
A road surface evaluation apparatus includes a microprocessor is configured to perform: calculating a roughness value of road surface corresponding to a predetermined period based on driving information of the plurality of vehicles during the predetermined period; and outputting roughness information including the roughness value. The microprocessor is configured to further perform, when calculating the roughness value corresponding to a second predetermined period, estimating whether a magnitude of a change rate of the roughness value corresponding to the second predetermined period with respect to the roughness value corresponding to a first predetermined period exceeds a predetermined threshold to acquire, when the magnitude is estimated to exceed the predetermined threshold, more pieces of the driving information to be used for calculating the roughness value corresponding to the second predetermined period than when the magnitude is estimated to be equal to or less than the predetermined threshold.
