Australian National Risk Assessment Model (ANRAM)

Australian National Risk Assessment Model (ANRAM) uses the iRAP Star Rating methodology and actual historical crash data to provide enhanced fatality and serious injury estimates for Australian roads.

The model was developed as part of an MOU agreement between Austroads, AAA, ARRB and iRAP and uses a Bayesian analysis to blend the iRAP FSI Estimates and actual crash history into the ANRAM FSI estimate. Severe crash history is used to supplement the predicted results, and in doing so, accounts for road user and other location-specific risk (e.g. speeding, drink driving, fatigue).

The approach requires high-quality geo-spatial crash data to develop the local models and integration within ViDA can be enabled. ANRAM is an internal tool used by Australian road authorities and is not currently available for global use.
