I-kaz 3D is developed to monitor whole-body vibration (WBV) in the driver's seat.
I-kaz 3D coefficient is generated to represent WBV from the driver's seat.
The dirt road with a rough surface has a higher value of IRIavg than the tarmac road with a soft surface.
The developed models for and VDV(8) have high R2 value for both types of roads.
Predicted WBV exposures generated by the regression models were close to the measured WBV exposures.
