Car owners’ experiences with (intelligent) in-car speed controlling systems. High speed has an adverse effect on road safety. Various attempts have been made to reduce traffic speed. Intelligent Speed Adaptation systems (ISA systems) work by actively or passively warning the driver or limiting the vehicle when the prescribed speed limit is exceeded, depending on where the vehicle is at that moment. The current trend in the motor industry is to develop more in-car speed controlling systems to support the driver which can intervene and/or advise on driving speed. There are standard Cruise Controls (CC), Intelligent Cruise Controls (ICC) which also regulates the distance from vehicles in front and there are speed limiters which help the driver to not exceed a certain self-selected driving speed. To be able to judge whether such systems have a positive effect on achieving the policy goals of improved road safety, traffic circulation and environment, the Ministry of Transport, Public Works and Water Management (Ministerie van Verkeer en Waterstaat) decided to have a user study carried out.
