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 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…
