This report documents a project to update the Guide to Road Design with Austroads recent research. The Guide parts will be released over the next six months.
Recent Austroads research reports have been reviewed and any improvements have been identified and assessed for their impact on the Guide to Road Design.
The improvements related to updating design practices based on the outcomes of the research and possible amendments have been developed and incorporated as updates to the Guide.
Thirty reports were reviewed, and the Road Design Task Force determined the application of the recommendations and inclusion within the Guide to Road Design.
The review also identified possible amendments to the Guide to Traffic Management and Guide to Road Safety, and these have been highlighted in the report.
To assist in incorporating future research into the Guides, a procedure has been developed for Task Forces, that outlines the process from inception of the research project to amending the Guide. This process enables a consistent method to be followed and outcomes of research to be brought into practice in a timely manner.
Watch a webinar with Noel O’Callaghan and Malcolm Mak who presents a detailed overview of the report.
