Drivers' internal representation and supervisory control: a first model verification in relation to driving experience task demands and deteriorated vision.

Interim results are presented of an ongoing research project on which the behaviour of car drivers is described by a supervisory control model with two main elements 1) observation/prediction and 2) control, and an intermediate internal representation. This representation is a function of both the driver's cognitive and perceptual anticipation of relevant features of the driving environment and the visual feedback information from that environment.
