The Cebon method converts spatial spectral density into frequency domain.By combining the road surface acceleration,spatial spectral density can be transformed into acceleration spectral density.Using the method to process the actual measurement data of road load spectral density from various sensors,the level of the road surface can be evaluated using the feature parameter extraction method.After analyzing and processing all measured sections,the actual road surface condition of the users is evaluated based on the statistical results.The results show that the road surface in the measured area is generally level and most of it is concentrated in the B class.
