A driving simulator experiment was carried out to assess the effects of Intelligent Cruise Control (ICC) on driving behaviour. ICC is an in-vehicle system that automatically regulates a vehicle's speed and that is also capable of maintaining a proper following distance behind a lead vehicle. ICC can realize a moderate level of deceleration: in situations that require hard braking, the driver must take over control. The results showed that ICC yields more consistent longitudinal control: in car-following situations, there is less variation in headway and in speed. It also appeared that when driving with ICC, subjects select a lower free-driving speed compared to their driving speed on the same scenario without ICC. In the critical scenarios where the subject had to take over control from the ICC, a later reaction was found especially in the first runs of the experiment. There was no difference between the foot-on-gas and the foot-off-gas ICC types in terms of driving behaviour. The questionnaire results, however, showed that subjects were highly in favour of the foot-off-gas type ICC, even though the overall judgements of both ICC types were positive.
