Kinematic Description of Hip and Knee Marker link system of Taxicab Operator

Abstract

Driving automobile especially as applied to occupational driver is a very tasking activity involving a number of body segments coupled with high level of vigilance required to minimize occurrence of accidents and musculoskeletal disorder (MSD). A kinematic study of each segment of human operator of technological system help to evaluate the dynamics of the link system and internal forces required in driving activities. In this work Newton’s second law of motion was applied to study the motion of human hip and knee marker link system and to develop bio-kinematic model for determining some kinematic parameters of the system. The model is capable of suggesting the variability of driver seat for effectiveness, safe and that minimise MSD in the operation of vehicle. Likewise the intensity, frequency and duration of exposure to harsh driving conditions can be regulated with appropriate threshold limit value (TLV) established.
