Previous researchers have developed hierarchical approaches to describe driver behaviour and have postulated models in which changes at higher levels in a hierarchy affect characteristics at the lower levels. Thus, in research on behavioural adaptation it is important to investigate not only driving performance outcomes (that are mainly represented on lower levels) but also the characteristics of motivational factors that are represented at higher levels. The two motivational factors that have already been considered in past research dealing with the effects of driver assistance systems are trust and acceptance. According to motivational theories, another factor that should now be considered here is perceived risk as it is, theoretically, highly related to potential changes in driving behaviour. In this chapter, the role of motivational factors including perceived risk, perceived behavioural control, norms, attitudes and intentions when drivers use ADAS is discussed. Reference will be made to an extended version of the theory of planned behaviour and to motivational driver behaviour theories.
