Safe System FindingsThe aim of Safe System Findings is to focus the Road Safety Audit process on considering safe speeds and by providing forgiving roads and roadsides. This is to be delivered through the Road Safety Audit process by accepting that people will always make mistakes and by considering the known limits to crash forces the human body can tolerate. This is to be achieved by focusing the Road Safety Audit on particular crash types that are known to result in higher severity outcomes at relatively lower speed environments to reduce the risk of fatal and serious injury crashes. The additional annotation “IMPORTANT” shall be used to provide emphasis to any road safety audit finding that has the potential to result in fatal or serious injury or findings that are likely to result in the following crash types above the related speed environment: head-on (>70 km/h), right angle (>50 km/h), run off road impact object (>40 km/h), and crashes involving vulnerable road users (>30 km/h), as these crash types are known to result in higher severity outcomes at relatively lower speed environments. The exposure and likelihood of crash occurrence shall then be considered for all findings deemed “IMPORTANT” and evaluated based on an auditors professional judgement. Auditors should consider factors such as, traffic volumes and movements, speed environment, crash history and the road environment, and apply road safety engineering and crash investigation experience to determine the likelihood of crash occurrence. The likelihood of crash occurrence shall be considered either “VERY HIGH”, “HIGH”, “MODERATE” or “LOW” and this additional annotation shall be displayed following the “IMPORTANT” annotation on applicable findings. Safe System Findings Explanation and ExampleControl DataWhat is Control Data? Control data is documented sources used to support identified road safety audit findings. The new road safety audit templates provide a road safety audit finding structure that promotes the use of ‘Control Data’. Why do we need to refer to Control Data’? Control data is used to support road safety findings and provides a more evidence based scientific approach to road safety audit delivery, by minimising the application of subjective opinion. Examples of sources of control data could include:
Using ‘Control Data’ is not a standards check. ‘Control Data’ should be used to support your findings and minimise the application of subjective opinion in the delivery of road safety audit to achieve better outcomes. The benefits of using ‘Control Data’ to support your road safety audit findings include:
