Drivers' acceptance of automatic speed limiters: implications for policy and implementation

It has been suggested that speed limiters will have the most impact on vehicle speeds and hence road safety in general. Whilst it is technically feasible to develop a functional speed control system, it may be more difficult to design a system that drivers actually wish to use. It is essential that drivers' acceptability towards speed limiters is gauged in order to establish the most effective way to implement the system. The research reported here used a variety of techniques to evaluate acceptability and concluded that although drivers perceive speed limiters to be effective in reducing accidents, there is a need to change perceptions about possible impacts on comfort and safety.
