This talk highlights some of the gains that can be had from reaching across the cross-disciplinary gap between engineering on the one hand, and psychology and neuroscience on the other. To this end, the talk briefly outlines a driver modelling framework that has been previously proposed by the presenter, and then describes how this framework has engendered new research hypotheses and results of applied engineering relevance. The modelling framework draws on knowledge from contemporary neuroscience and psychology, and construes driver control behaviour rather differently from many existing models, especially if comparing to models that have been put to use in applied engineering contexts. The follow-on research and results that have built on predictions from the framework include an improved understanding of driver response in crashes and near-crashes, improved estimates of safety benefits of collision avoidance systems, new perspectives on the effects of driver impairment and distraction, and objective methods for fidelity assessment of driving simulators. Cross-fertilisation can also happen in the other direction, with psychological accounts of the driver being informed by concepts from vehicle engineering.

14. Summary / reflections
• Reaching from an applied question to ideas and
concepts from more basic sciences
• Key here: Constrained applied problem
provided focus
• Resulting cross-disciplinary connection proved
a rich source of new ideas and applications
• Mechanisms grounded in more basic sciences
applied models more likely to generalise
15. Pros and cons of cross-disciplinarity
• Potential for low-hanging fruit
• Personal development, fun
• More difficult to communicate
