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…

While truck tracking characteristics are a primary consideration for intersection geometry and curve widening practices, most road geometric design standards, particularly alignment design standards, are based on the performance characteristics of…

Variations exist in the methods and practices used by each of the authorities for the assessment of route access, yet increasing vehicle productivity without compromising safety underlie all of their heavy vehicle route access assessment procedures.…
