Driver Behaviour During Braking

Data is first presented of how accurately a driver can judge his pedal effort, deceleration, speed, and distance from a stopping point. Typical braking behaviour obtained by drivers under controlled conditions is then described, both for car and commercial vehicle drivers and, based on this evidence, a mathematical model is presented for the driver in the braking situation. The simulation study based on that model is discussed with reference to comparative results obtained from road tests.
