Australian state and territory road authorities have adopted a “Safe System” approach. Crucially, this approach recognises that humans inevitably make mistakes that can result in crashes, and therefore road infrastructure should be designed to accommodate these errors in a way that reduces both the likelihood and severity of crashes. Unfortunately existing road intersections do not comply with Safe System principles.

Most notably, existing intersections permit high travel speeds and impact angles that are greater than the human body can tolerate in the event of a crash, which can result in serious injuries and fatalities. In order to improve intersection safety, we designed a range of new treatments that could feasibly be adopted at existing road intersections, and evaluated their performance across three driving simulator studies.
