Pavement roughness has a huge influence on driving comfort. As the progressive growing of motor vehicles, it is an important issue to effectively and quickly collect pavement information and prevent road congestion from lane closure when doing road test. This research compares the applicability of each roughness index and roughness instrument to recommend related organizations. The International Roughness Index, IRI is the index which is suitable for large-scale test, and the wavelength it can detect is close to human bodys sensation of vertical acceleration. The research also improves the self-developed inertial profiler based on previous generation, the instrument can now collect data on two side of the car instead of one side to improve the reliability in the process of road network test. The research finally compare the related regulation of inertial profiler and find out that the accelerometer, displacement sensors and numerical verification of domestic inertial profiler is incomplete and needs to be refined.
