Original Abstract Submitted
A road surface evaluation apparatus includes a microprocessor configured to perform: acquiring driving information of a vehicle which is traveling including acceleration information, speed information, and position information of the vehicle, acquiring map information including information on a road on which the vehicle travels, acquiring weather information including information relating to weather; deriving a road surface roughness value representing roughness of a road surface on which the vehicle travels based on the driving information of the vehicle estimating the weather in a section where the vehicle has traveled based on the weather information to correct the road surface roughness value based on the estimation result; and outputting the road surface roughness value in association with the information on the road.
