Gabby O'Neill presented at the AITPM 'Back to Basics' seminar on the Safe System Approach. The presentation covered South Australia's road fatality data from 2007 to 2016 and examples of road safety treatments implemented, including guard rails, wire rope barriers, shoulder sealing, controlled right turns at signalized intersections, and raised intersection platforms. It concluded that while people make mistakes, road deaths are not inevitable, and using safe system thinking in infrastructure design with elements like lower speeds and dedicated turn lanes can help prevent crashes and reduce injuries.

Examples showing before and after treatment (Tea Tree Gully Mannum Rd) Guard fence reduces the risk of runoff road crash by up to 30 per cent Guard Fence
Motorcycle Crash Cushions The motorcycle barrier system is attached below the guard rails, absorbing fallen rider impact and gently deflecting them back towards the road. Safer Roads for Motorcycling

Road Safety Treatments: Run-ofCrashesTreatment: Right Turns, Signalised Intersections Signalised Intersections Over 500 signalised intersections within South Australia. Sites where crash rates are higher undergo investigations. Volume of right turn traffic and or opposing traffic is high. Visibility of oncoming traffic is less than required for safe gap selection. Reduce opportunities for motorists to filter right turn. Controlled Right Turns are when the red arrow remains on during the through vehicle phase. Generally used because of the history of right turn crashes. Positive results.
