Road roughness is a broad term that incorporates everything from potholes and cracks to the random deviations that exist in a profile. To build a roughness index, road irregularities need to be measured first. Existing methods of gauging the roughness are based either on visual inspections or using one of a limited number of instrumented vehicles that can take physical measurements of the road irregularities. This paper presents used a quarter car model (passive suspension System in 206 Peugeot) in according road classification ISO 2631-1 is achieved road roughness interval in form of optimization method Gamma (4p) distribution as PSD function in different constant speed of car (34, 70 and 100 Km/h) by using Matlab Code. Finally, to have accurate results and to describe effect of vehicle velocity on irregularity surfaces incoming Automotive Suspension System, are compared road roughness in terms of travel length and PSD function in terms of Frequency Hz.
