Speed regulation by in-car active accelerator pedal – Effects on driver behaviour

Hjälmdahl, Magnus LU and Varhelyi, Andras LU (2004) In Transportation Research. Part F: Traffic Psychology and Behaviour 7(2). p.77-94
Abstract
The long term effects of driving with an active accelerator pedal (AAP) on driver behaviour was studied by using an in car observation method. The AAP produced a counterforce in the accelerator pedal when the speed limit was reached, it could however be overridden by pressing the accelerator pedal harder. Twenty-eight drivers were studied when driving without the AAP and then when driving with the AAP after they had used the system in their own cars for at least six months. The results showed that the behaviour towards other road users improved, they had a correct yielding behaviour to a higher degree and were more likely to give pedestrians the right of way at zebra crossings when driving with the AAP. It was also found that the headway... (More)

The results showed that the behaviour towards other road users improved, they had a correct yielding behaviour to a higher degree and were more likely to give pedestrians the right of way at zebra crossings when driving with the AAP. It was also found that the headway to the vehicle in front increased slightly with the system. There were also signs of negative behavioural modifications in the form of drivers forgetting to adapt their speed to the speed limit or the prevailing traffic situation when they were not supported by the AAP. These effects, however, were statistically not significant. (Less)
