The Australian National Risk Assessment Model (ANRAM) provides a system to implement a nationally-consistent risk-based road assessment programme, to identify road sections with the highest risk of severe crashes.
ANRAM is a nationally agreed approach that has built on existing Australian and international risk-based road safety programmes such as AusRAP, NetRisk, iRAP and KiwiRAP, to create a system directly relevant and applicable for Australian state and local road agencies. Development of ANRAM was funded by Austroads and guided by Australian road agencies.
ANRAM predicts severe crash risk based on the relative safety performance of road infrastructure, traffic speed, flow and potential for vehicle conflicts. Severe crash history is used to supplement the predicted results and account for road user related risk. Road sections may be ranked on the basis of individual and collective risk of severe crashes.
The ANRAM Toolkit went live in April 2014 for trial by Australian state, territory and local road agencies via ARRB. It has been implemented nationwide in Australia since, with results informing the basis of AUSRAP’s Risk Mapping Reports.
