Driver Performance
Measurement
INTRODUCTION
To evaluate different vehicle designs, vehicle features, and the effects of changes or improvements
made in vehicle designs, an ergonomics engineer should be able to measure and demonstrate how
well the driver performs in different tasks while using the vehicle. Currently, there are very few
standardized measures (or variables) and methods for measurement of driver behavior and driver
performance. A number of researchers have used many different measures, and there is some agree-
ment on the general approaches for performance measurements. However, many differences in
