Samenvatting
The effects of the Active Accelerator Pedal (AAP), on speed behaviour of drivers with different backgrounds and attitudes was ana lysed. It was found that most of the drivers initially reduced their speed to the speed limit. However, after driving with the system for a while, speeds increased. Drivers who had a high speed without the AAP started to speed again. This finding suggests that an advisory system, such as the tested AAP, is efficient in reducing the speed of drivers who are speeding inadvertently, but it is not as efficient, however, in reducing the speed of drivers who speed deliberately.
