Road unevenness characterization


Summary

Research is focused on vibration analysis in the road-vehicle-driver interaction system and analysis of real longitudinal road profiles as a source of vibration to improve characterization of longitudinal road profiles. Results are intended to be used in road management and road maintenance.

Objectives

The research activities are mainly devoted to:

Achievements


Road characterization Sample of the same value of frequency-weighted acceleration on the driver’s seat (awds) for two road profiles with different spectrum properties
