Abstract: In India semi low floor (SLF) buses are used for shuttle within the cities. The main objective of the paper is to develop a quadratic model for prediction of driver seat vibration and analysis of relationship between the seating parameters and driver seat vibrations. Response surface methodology (RSM) was used to develop the regression model in SLF bus driver comfort. In the development of the predictive model, seating parameters backrest inclination, horizontal distance from the ABC pedal, foam thickness and speed were considered as model variables, seat vibration was considered as a response variable. The statistical analysis showed speed was found to be the most significant process parameter to influence seat vibration. Other parameters were found to be insignificant but the interactions among them were found to be significant. Apart from objective analysis, the subjective assessment parameters comfort, visibility and confidence also studied for all the trials.
