iRAP Factsheets now available

29 July 2013

To coincide with the first major update of the iRAP methodology since it was pilot-tested in four countries in 2006, iRAP has  published a new series of fact sheets.

The 28 fact sheets describe the risk factors (or crash modification factors) used in the models for attributes such as lane width and sidewalk (footpath) provision, and include discussion on key issues and references to published literature. The fact sheets are available at here and on the Road Safety Toolkit.

We are also in the process of updating the existing methodology documents, addressing topics such as the way in which crash initiation modes are handled in the models and how the Star Rating thresholds are set. The documents will be free to download when they’re ready.

In the meantime, if you have any questions about the iRAP methodology, the team will be happy to answer questions and can be contacted here..
