ABSTRACT
Traditionally, models of behavioural adaptation focus on observable constructs such as performance or capabilities that change in the presence of an intervention (e.g., the task-capability interface model; Fuller et al., 2008). The interventions are manifested as changes in the environment in which drivers operate. Examples of these are in-vehicle modifications (Chapter 9), alterations to the road infrastructure (Chapters 7 and 8) or changes in road safety policy (Chapter 10). However, there are mediating processes that influence behaviour aside from those already discussed, including those of acceptance and acceptability. This chapter will present models of acceptance, drawing on those developed in the new technologies field and discuss how they might be used to explain adaptations in road users’ behaviour.
