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…

Guidance on Median and Centreline Treatments to Reduce Head-on Casualties
This report presents a compendium of local and overseas practice and experience in minimising the risk and severity of head-on crashes. It is intended to assist road safety practitioners identify effective actions that can be taken to reduce the…
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…

Road Safety Engineering Risk Assessment Part 11: Road Safety and Maintenance
To assist member authorities in the management of road assets to provide better safety outcomes, this research program has been developed to assess the safety implications of road deterioration, the safety benefits of asset restoration, and the…
Road Safety Engineering Risk Assessment Part 4: Treatment Life for Road Safety Measures
All road and traffic authorities need to direct their funding wisely to road safety treatments that ensure the most cost-effective returns in crash and injury reductions. In order to do this, accurate information is required on the expected benefits…
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…

Heavy Vehicle Sight Distance Requirements at Rail Crossings (Stage 2)
Passive control railway level crossings within the road network pose a significant safety issue, both for trains and multi-combination vehicles (MCVs) and restricted access vehicles (RAVs0. In order to have provision for the larger MCVs and RAVs,…
Road Surface Characteristics and Crash Occurrence: A Literature Review

The starting point for this review was the recently-published Austroads Guidelines for the Management of Road Surface Skid Resistance. Skid resistance, which depends on both microtexture and macrotexture, is currently the road surface characteristic…

Further aspects of the relationship between geometric features and crashes
This project had its origins in an earlier project which showed that crash rates increased at extremes of horizontal and vertical geometry, and were lowest with narrow sealed shoulders. This paper reports an investigation based on the original…
Relationship between Crash Risk and Geometric Characteristics of Rural Highways
This paper reports a study which brings together information on road geometry (curvature and grade), cross-section, traffic flow and crashes. It allows the influence of these other factors on road crashes to be assessed in ways not possible before.…
