So far, different theories and methods, also stemming from other domains, have been used to define and conceptualize the notion of acceptability. Previously we developed a theoretical concept to define acceptability of ISA based on different theories and methods used in ITS & ISA research. In the current paper we aim to find out which predefined indicators are relevant to define the acceptability of ISA. Background factors, contextual issues and ISA-device related factors are used as indicators to predict the level of acceptability. Structural Equation Modelling (SEM) is used to define the direct and indirect effects.

Several trials with different types of in-car speed assistance systems, in particular Intelligent Speed Assistance (ISA), have shown that ISA can be an effective way to reduce speeding. A basic condition for achieving significant improvements in safety involves the acceptance of ISA among vehicle drivers on a large scale. This paper focuses on the issue of acceptability of ISA. It is based on a large-scale survey of 6370 individuals in Belgium (Flanders region) and 1158 persons in the Netherlands. The methodology to define our concept, the construction of the questionnaire, first descriptive results and the future steps in the development of our model are described.
