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…

The provision and maintenance of safety infrastructure such as safety barriers and safety fences enhances roadside safety and vehicle movement and reduces the risk of road crashes and their severity. This report provides guidance for the management…

This report provides a synthesis of key safety solutions as well as issues that need to be considered when effectively addressing safety on urban mixed use arterial routes.

Mixed use urban arterials account for a large proportion of high?severity…

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…

This report summarises the findings from the first year of a three-year study which reviews the safety performance of road infrastructure elements identified as Safe System solutions. The first stage sought to identify these solutions and to…

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…

Run-off-road crashes result in a high number of serious casualty crashes in rural environments. It is therefore important, within a Safe System, that factors that contribute to this type of crash and methods that may be used to prevent them from…

The Safe Systems approach has been adopted in Australia and aims to provide a road system that protects responsible road users from death and serious injury. A Safe System approach recognises that road users are fallible and will continue to make…
