The Sixth International Conference on Traffic and Transport Psychology (ICTTP2016), organised by QUT’s Centre for Accident Research and Road Safety – Queensland (CARRS-Q) and Griffith University’s Menzies Health Institute Queensland took place in Brisbane, Australia, on 2-5 August 2016. It was the first time an ICTTP has been held in the Southern Hemisphere and only the second time outside of Europe. The Conference was a global forum, with a theme of “UN Decade of Action For Road Safety: The Half-way Point”, at which nearly 400 road safety experts from 39 countries attended, including researchers, practitioners, policy-makers and industry from the areas of public health, law, medicine, economics, law enforcement, public policy, education, human factors, and psychology met, presented and discussed on the latest work being undertaken in these areas.
