Trauma estimation

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.

RAP Tools to Support the Global Plan

iRAP and its partners have developed a suite of tools that use the iRAP methodology to support the Global Plan for Decade of Action for Road Safety 2021-2030, which sets a target of 50% reduction in road deaths and injuries.These RAP Tools also support the achievement...

iRAP Star Rating model features in new Austroads guides to help develop sustainable network safety plans

The two-part guide aims to help road managers, planners and designers create plans that reduce serious and fatal crashes, deliver self-explaining roads and facilitate decisions resulting in the safest network. The guides are entitled "Road Cross-section Design for...
