According to the present invention, a method for analyzing conditions of a road surface includes the steps of: receiving, by a signal processing unit, an image signal obtained by capturing a vehicle and an audio signal, which is noise generated on the road as a vehicle runs; detecting, by the signal processing unit, an audio signal of interest in a frequency band of interest from the received audio signal to generate the audio signal of interest; and recognizing, by a recognition unit, the conditions of the road surface by analyzing the image signal and the audio signal through one of a learned vehicle type recognition model and a plurality of learned condition recognition models.
