【 摘 要 】

Speed Control Humps (SCH) are used to slow down the vehicles and improve traffic safety. While passing over the humps, the drivers of public transport buses are exposed to shock vibrations. An analysis of the effects of shock vibrations to the health of a city bus driver, while passing over three types of SCHs, is made by simulation, using an original oscillatory model with five degrees of freedom (DOF). The evaluation is carried out using the method and criteria accepted by ISO 2631-5 standard. The assessment of the effects of shock vibrations to the health of the bus driver on public transport line 26 in Belgrade is also made. While passing over a rounded profile, the driver's health is more affected at lower bus speeds (15 km/h), even as over flat platform, harmful effects are more significant at higher speeds (over 40 km/h). If the bus on the line 26 is driven over humps at 40 km/h, harmful effects to the driver's health occur at the age of 50. By driving at or under 30 km/h, the driver can almost avoid harmful effects at all.
