ABSTRACT
In-vehicle systems for car drivers with the aim of informing, gtvmg advice, warning or taking over in different situations, are developed rapidly. Examples of applications of such systems are speed control, incident warning, visibility improvement, navigation aid etc. The purpose of these systems is to increase safety, reduce pollution and/or to increase mobility. There is an extensive amount of research on the potentials and possibilities of these systems, but there are still many problems to be solved, which relate to how the driver reacts to and uses the systems. Examples of problems are level of acceptance, adjustment of the systems to differences in driver preconditions, impact of driver motives on how the systems are utilized, overestimation of the abilities of the systems etc. Several of these problems are relevant for drivers in general, but there are also reasons to expect specific problems when young novice drivers use the systems. Several of the problems generally regarded as important for the safety of young novice drivers may also have important impact on the potential in this group. This relates for example to their high mental workload, overestimation tendencies or typical young driver motives. VTI carried out this study with the aim of defining such young novice drivers' typical reactions and use of these in-vehicle systems.
