A cross sectional study was conducted to analyze a relationship between bogie locations and the ride performance in a monorail car. This study was carried out t* determine exposure levels of whole body vibration in a certain location in a monorail car and related to various condition path of the beam. Human Vibration Meter (HWl) 100 Larson Davis and Whole Body Vibration (WBV) sensor as a device were used to measure at 2 positions within 3 locations inside a monorail car and 3 different paths of beams. The measurement of whole body vibration was done on a consumer monorail in operation and service during off peak hour. The data in the form magnitude collected and recorded by HVM 100 was transferred to the computer using Blaze software. The analysis of graph pattern and the difference of magnitude value for each location inside a car was studied to determine the exposure level of vibration. Data was evaluated and the results show high magnitude vibration for all / three axes x, y, z which are 6.92 &st, 4.61 m/s2, and 3.9 m/s2 respectively, The Vibration Calculator was used to calculate the risk of WBV in the daily vibration exposure that a passenger is subjected to comply health and safety requirements. The finding showed there are relations between bogie location and vibration exposure, which resulted over the allowable exposure limit value 1.15 m/s2. The individual subjected to frequently vibration exposure would tend to receive higher rate transmission of vibration in the body and will cause health problem. Among the improvements suggested reducing the vibration such as by putting the seat with a cushion, rubber padding on the floor, and installing more hand pole at the center of the car.
