Original Abstract Submitted
A road surface evaluation apparatus includes a microprocessor configured to perform: acquiring driving information of a plurality of vehicles which are traveling, including acceleration information, speed information, and position information; acquiring map information including information of a road on which the plurality of vehicles travel; deriving a road surface roughness value representing a roughness of a road surface on which the plurality of vehicles travel for each speed range based on the acquired driving information of each of the plurality of vehicles; correcting, for each speed range, the road surface roughness values derived for each speed range, and combining the road surface roughness values corrected for each speed range to derive a corrected road surface roughness value; and outputting the corrected road surface roughness value in association with the information of the road.
