Risk Ratings Explained.
Most crashes occur when ordinary people make everyday mistakes. By building safer roads, we can reduce the number of crashes, and reduce the severity of those that do occur.
AusRAP recognises that we need to work towards a system of five star drivers in five star cars on five star roads. All three need to work together to achieve a safe road system.
AusRAP Risk Maps take these elements of vehicle safety into account by examining the crash history of the road network. Performance Tracking allows the safety performance of a road to be tracked over different time periods.
Risk Maps.
Collective Risk Maps show the density, or total number of crashes on a road over a given length. Collective risk is calculated by dividing the number of casualty crashes on a link by the length of the link.
Individual Risk Maps show casualty crash rates per vehicle kilometre travelled. This is the risk rate for individual drivers. Individual risk is calculated by dividing the frequency of crashes by the distance travelled by vehicles on each road link.
Risk Maps have been produced for the National Highway Network,on which roads crash fatalities typically account for around 15 per cent of Australia's annual road fatalities.
Beware of our killer roads and highways.
