Abstract
The validation of a mathematical driver model for an obstacle avoidance manoeuvre is described. The major portion of the investigation was devoted to the gathering of data on driver behaviour while controlling a car and a truck under these conditions. This was carried out in a fixed-base driving simulator employing a computer generated display of the driver's forward view. The obstacle avoidance maneuver was trigged by the fall of on pole of many lining the road in front of the driver.
