Benyond road rougness- interpreting road profile data

摘要

Advances in laser technology and data acquisition systems have led to the development of so-called profilometers that can measure road surface profiles at relatively high speeds at reasonable cost. These devices collect vast amounts of data that need To be processed and reduced to provide useful Information. Existing options include calculating The International Roughness Index(IRI)values, or Using Fourier analysis as described in the ISO 8608 Standard, published by the International Standards Organisation in 1995.
