Crash Risk Mapping
Crash Risk Maps use detailed crash data to capture the combined risk arising from the interaction of road users, vehicles and the road environment. Risk Maps provide an indication of the overall road system performance.
The maps provide an at-a-glance and objective view of where fatal and serious injury crashes have occurred and where serious crash risk is greatest. Using a global methodology allows benchmarking where desired (e.g. crash rates on motorways; pedestrian crash rates in cities). Primary metrics include crash rates per kilometre/mile and crashes rates per kilometre/mile travelled with more detailed versions including road user, age group or in relation to average crash rates for that road type.
Crash Risk Maps and Star Ratings are often used together as part of a strategic approach to managing risk and investment. They also provide a useful source of calibration for FSI Estimates and Investment Plans.
