Veiligheidsaspecten bij een grootschalige proef met Intelligente Snelheidsaanpassing (ISA) : opzet van een evaluatiekader aan de hand van open interviews.

Safety aspects in a large-scale experiment with Intelligent Speed Adaptation; The design of an evaluation framework using open interviews. All sorts of in-vehicle Intelligent Transport Systems are being designed and, in the meantime, a number of `simple' systems have already been introduced. Until now however, safety evaluations are often limited and onesided. The safety effects that are expected, for example those based on studies with traffic simulators or an instrumented vehicle, will have to be confirmed in well-designed large-scale practical tests. This study, therefore, deals with the design of such an evaluation study. This project attempts to draw up a so-called evaluation framework with safety aspects that should be included in a large practical study. To do this, 10 experts were presented with a case: a large-scale practical test with Intelligent Speed Adaptation (ISA). All experts were or had been involved in the design and carrying out of large-scale ISA tests in the Netherlands. In open interviews, the experts were asked to indicate all possible safety problems after large-scale implementation of ISA, and to explain them further. The following points were dealt with: the cause of the problems, the extent to which they may be allowed to occur, the possibility and necessity of measuring the problems, and how they can possibly be prevented. Finally, every expert was asked to rank the `own' list of safety issues mentioned according to importance.
