Abstract

Intelligent Speed Adaptation (ISA) could be implemented in a number of ways. The technology exists to implement systems that are purely advisory, or ones that actually control the maximum speed allowed. A compromise would be to introduce a system that allows a driver to choose when to engage ISA, thus creating a "voluntary" system. Whilst on the surface this appears to be an appropriate solution in terms of driver acceptability, there are a number of issues that are of concern - the most obvious one being the likelihood that drivers will not engage such a system if they deem it unnecessary or they dislike it. This type of "selective recruitment" may seriously devalue the safety benefits of a voluntary ISA system. This paper describes two studies that examined the relationship between drivers' reported and actual speeding behaviour, their propensity to engage a voluntary ISA system and their attitudes towards such a system. These studies were carried out in a driving simulator and on-road and provide some interesting results of relevance to the implementatation policy adopted for ISA.
