Typical braking behaviour exhibited by drivers under controlled conditions is described, and it appears that the behavioural system is structured with successive organisation of perception. The first level corresponds to a simple comparative tracking task and the second level includes in addition proprioceptive feedback and an element which operates on the system input such that predictive behaviour becomes possible. The third level involves a repertoire of remedial action and other programs which the experienced driver establishes, and uses when the cues are appropriate. A comprehensive mathematical model has been developed which models the first two levels, and agreement between braking data simulated by the model with data obtained from measurements made in the field is good. The model was further refined by taking into account pitching motion of the vehicle during braking but it was found that this was not needed for normal motoring, although it could be important if the vehicle pitches violently over rough terrain. As the mathematical model simulates the first two levels very well, it has now to be extended to include the third level, which represents the adaptive ability of the driver. /Author/TRRL/
