The analysis of ride quality dependent of road surface roughness

Poor road construction, insufficient maintenance and a large number of heavy vehicles influence on appearance of road surface irregularities. Certain irregularities such as recessions, bumps, manholes, etc. significantly increase vehicle vibrations, reduce driving comfort and cause additional expenses for vehicle repairs and road reconstructions. This paper presents an experimental investigation of personal vehicle vibrations caused by irregularities on road surfaces in Zagreb (Croatia). Vibrations were measured using an accelerometer at two measurement points: on the front right wheel and on the vehicle chassis. The results of this investigation could serve to propose recommendations as to which road irregularities require reconstruction or maintenance in order to reduce vibrations and increase driving comfort. These recommendations according to road roughness associated with vehicle vibrations should be an integral part of road comfort and safety management.
