J. Cent. South Univ. (2021) 28: 2451-2462 DOI: https://doi.org/10.1007/s11771-021-4779-6 Application of signal processing and support vector machine to transverse cracking detection in asphalt... pavement condition (roughness and obvious anomalies) monitoring has been expanding in road engineering. However, the indistinctive transverse cracking has hardly been considered. Therefore, a vehicle......
