System failures and extreme behavior in fatal and injury crashes in South Australia

Overall, the findings suggest that strategies continuing to focus on system wide improvements to the road transport system such as providing safe road infrastructure (e.g., side and center barriers) and the accelerated uptake of safe vehicle technologies (e.g., lane keeping technology, autonomous emergency braking) can be expected to be effective in reducing the incidence and severity of a large proportion of fatal and serious injury crashes. For more extreme behaviors, greater control of road user behavior may be required through the increased use of vehicle technologies and more holistic social health initiatives.
