Whole-Body Vibration Exposure Experienced by Subway Train Operators

Abstract

Purposes of the study were to measure mechanical vibrations transmitted to train operators, to calculate daily whole-body vibration exposure levels, to compare measured levels with maximum acceptable exposure levels according to the international standard on whole-body vibration, to identify factors that influence vibration levels, and to quantify the effects of these factors on the measured levels. As a result of this study, it was determined that six out of twenty subway lines had vibration levels higher than the daily exposure limits recommended by the international standard, and that train speed was the most significant factor influencing the vibration levels.
