We investigated the difference between truck drivers and other drivers at the aspects of fatigue and the workload influencing on drivers' fatigue. In the result of analyzing about the six sub-factors of NASA -TLX, influencing on the drivers' fatigue, physical demand had significant impacts on two driver group's subjective fatigue. However, mental demand and temporal demand showed significant effect on only truck drivers' subjective fatigue. The physical demand influencing on the drivers' subjective fatigue may be expressed that drivers' muscles stiffness caused by posture restriction in the car. The effect of mental demand and temporal demand on the truck drivers' subjective fatigue had relation to the environment of logistics transportation in Korea. That is, truck drivers are not usually employed by companies but work as individual. For this reason, time equals to money for truck drivers and this affects on mental demand and temporal demand, related with scheduling. We are expecting that this finding would aid to produce a effective measure in order to decrease the truck drivers accidents and the risk on account of fatigue.
