The current research details the urban minibus drivers comfort levels. These buses are used for shuttle services within the city as well as school services. Long seating is a vibrant risk factor for back pain for minibus driver’s exposed to whole body vibration (WBV). In this paper, effects of seat inclination, speed and seat distance from the ABC pedal on seat acceleration are investigated by the statistical methods of analysis of variance (ANOVA), Taguchi’s orthogonal array, regression analysis. Process parameters are prioritized by Taguchi’s L27 orthogonal array. ANOVA determines the significance and percentage contribution of each parameter. Seat inclination has a greater contribution on ride comfort followed by the speed and seat horizontal distance. To optimize the human comfort vibration in minibus, genetic algorithms and multiple regression models were used. The values predicted from experimental, regression model and genetic algorithms values are found to be in good correlation.
