Practitioners have raised concerns when designing for heavy vehicles with respect to the combination of design values for side and longitudinal friction demand as well as design criteria for horizontal curves with adverse superelevation. This report…

This report provides a compendium of recent and robust evidence on the relationships between twenty key geometric design criteria and safety outcomes.

The project critically reviewed quality research sources to identify crash modification factors…

This report draws on literature and crash data analysis to identify and quantify geometric road design elements which contribute to casualty crash occurrence and severity on rural roads, e.g. lack of sealed shoulders, steep downhill grades combined…

Heavy vehicle crashes across Australia and New Zealand continue to be a major road safety issue. There are road design criteria that are not based on the requirements of heavy vehicles and the purpose of this study was to update criteria for…

Intersection crashes are one of the more common type of crash that may occur in rural environments. It is therefore important, within a Safe System, that factors that may contribute to intersection crashes and methods that may be used to prevent…

This project forms part of an ongoing Austroads strategic research program to improve the understanding of the relationship between crash risk and road elements. This report provides a summary of the relationship between crash risk, and geometric…
