1. A road surface evaluation apparatus comprising
a microprocessor and a memory connected to the microprocessor, wherein
the memory stores map information including roughness information indicating a roughness of a surface of a road, and
the microprocessor is configured to perform:
acquiring as driving information of a plurality of vehicles driving on the road, position information of the plurality of vehicles, acceleration information indicating accelerations of the plurality of vehicles, driving image information including a captured image of the surface of the road, and driving sound information indicating driving sound of the plurality of vehicles;
evaluating the roughness of the surface of the road based on the driving information of the plurality of vehicles;
updating the roughness information corresponding to the road stored in the memory based on an evaluation result in the evaluating; and
outputting information on the evaluation result in association with the road information to at least a terminal or a display.
