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…

Following on from previous work, the purpose of this project was to complete an investigation of subjective ratings of ride quality of A, B and C roads in Victoria while driving a passenger car and a range of heavy vehicles.

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 documents the outcomes of surveys of road freight drivers, operators and road infrastructure managers to better understand their asset management level of service (LOS) requirements.

The survey responses identified three primary road…

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…

This report describes the preparation, testing and results from project TT1358: Cost-effective structural treatments for rural highways: Cemented Materials. Ten granular materials, with a variety of different characteristics such as normal to high…

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…

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…
