Truck Side / Longitudinal Friction Literature Review and Data Analysis
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…
Safe System Infrastructure on Mixed Use Arterials

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…

Verification of Austroads Road Design Criteria Based on Objective Safety Evidence

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…

Road Geometry for Improved Rural Safety

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…

Improving the Performance of Safe System Infrastructure: Stage 1 Interim Report

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…

Road Safety Engineering Risk Assessment Part 1: Relationships between Crash Risk and the Standards of Geometric Design Elements

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…

Infrastructure/Speed Limit Relationship in Relation to Road Safety Outcomes

The objective of this project was to provide advice to jurisdictions on appropriate speed limit setting policy in light of harm minimisation (the Safe System approach). This advice was based on the improved understanding of the relationships between…
