THE PERCEPTION OF DEVIATIONS FROM A STRAIGHT COURSE

An analysis of the steering task and the available visual cues shows that heading angle change and lateral position change could be the cues, directly perceived and controlled in driving on a straight road. In an experiment, using a signal detection paradigm, the thresholds for these cues were determined. A normal road with edge and centre lines as well as a random dot environment were used as visual fields. It was found that heading angle change has low thresholds for both kinds of environment, while lateral position change cannot be perceived in a random dot environment. The determined thresholds are not in conflict with some dynamic variables describing normal steering behaviour. It is shown that a number of variables influencing normal steering behaviour can also be related to these cues in a consistent manner.
