Vibration is a major cause of occupational diseases for vibrator driver. This paper presents an experimental method of determining the seat's driver vibration of the single drum vibratory roller under the different operating conditions. The experimental results are analyzed and evaluated according to the ISO 2631: 1997 (E) standard. The evaluation results have shown that the vehicle ride comfort is not satisfied the international standard, at the same time, it is also less than keep drivers work efficiency time TFD = 4 hours of operation requirements when it operates. In addition, the study results can provide an experimental basis for the optimal design for cab's isolation system of vibratory roller.
