Comparison of bus driving posture in USA and India

Abstract

The aim of this project is to compare driving postures in India and the USA in order to develop seat designs to improve driver posture. The postures of 14 bus drivers from the USA and 9 from India were evaluated by RULA (Rapid Upper Limb Assessment) analysis, and various seat dimensions from India ware collected and compared with standard dimension in the USA. For both countries, low posture occurred most frequently, showing a RULA score of 3, indicating a need for posture change and further investigations. Among drivers who exhibited high posture, posture in American drivers displayed a RULA score of 4, and posture in Indian drivers showed a RULA score of 6. Furthermore, the component ratio of the high posture group in India was about 10 times higher than that of the high posture group in the USA.
