Driver distraction is an important and growing risk factor for road traffic crashes. Distraction is a complex, multifaceted phenomenon and, despite its impact on safety, our understanding of it is far from complete. Using state-of-the-art driving measurement methods, this project will explore the role that driver initiated adaptive behaviour (self-regulation) plays in mitigating the effects of distraction on driving performance and safety. A set of new countermeasures designed to enhance drivers' self-regulatory behaviour when distracted will be developed and assessed. The outcomes of the project will revolutionise efforts to reduce the deleterious impact of distraction on road trauma in Australia
