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 investigates how the geometric design components of a roundabout may contribute to bicycle crashes.

In October 2016 Austroads delivered a two-part webinar providing an overview of the updated Guide to Road Design Part 3: Geometric Design. This second session covers horizontal and vertical alignment, and superelevation.

In October 2016 Austroads delivered a two-part webinar providing an overview of the updated Guide to Road Design Part 3: Geometric Design. This first session covers design objectives, speeds and cross sections.

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…

This report investigates whether the ramp acceleration lengths provided in the Austroads Guides are valid for modern Australian vehicles.

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 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…

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,…

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…
