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

This report summarises the findings of a three-year study which reviewed the safety performance of selected road infrastructure elements and provided solutions that were more closely aligned with the Safe System ideal.

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 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…
