Abstract:
Drivers’ posture is one of the factors that can contribute to driving discomfort. Subjective evaluation is needed in
determining the driving discomfort problem. The purpose of this study is to examine the reliability of different
driving postures that may lead to drivers’ discomfort. A total of thirty-four healthy Malaysian drivers were involved
in this study. Respondents were required to sit on the driver’s seat with the required adjustments of three different
postures and fill-in the given subjective evaluation form. The same procedure was repeated for each respondent
after three days for purpose of conducting test retest evaluation. The reliability statistical analysis result shows the
study was reliable and valid with a Cronbach’s alpha coefficient equal to 0.827. The comparison means that ANOVA
analysis also shows significance difference between these three groups of postures for all measured parameters. In
conclusion, the result from this study shows the subjective evaluation conducted is reliable and can be used for
drivers’ posture discomfort study.
