ABSTRACT
Our understanding of behavioural adaptation has come a long way since the 1990 OECD report. Theoretical underpinnings challenge the very definition of behavioural adaptation-what it is, why, how, and when it occurs, and by whom. Consequently, an updated definition of behavioural adaptation is offered that incorporates recent knowledge and experience in the field of traffic safety and, in particular, intelligent transport systems (ITS): ‘The collection of any driver, traveller, and travel behaviours that occurs following user interaction with a change to the road traffic system, in addition to those behaviours specifically and immediately targeted by the initiators of the change’. We support this updated definition of behavioural adaptation, as it recognises that, to keep up with the pace of technological progress, we need to be mindful of an ever-changing transport landscape.
