This report summarises the activities undertaken as part of a project to provide contemporary intersection design guidance and achieve timely updates to Austroads Guide to Road Design Part 4, 4A, 4B and 4C based on best practice evidence to improve…

This guide has been developed to assist intersection designers and contains:

Guide to Road Design Part 4: Intersections and Crossings: General contains guidance that provides road designers and other practitioners with information that is common to the geometric design of all at-grade intersections. It contains information…

The Guide to Road Design Part 4B: Roundabouts provides road designers and other practitioners with guidance on the geometric design of roundabouts. It covers design principles and procedures, and guidelines for all the key elements, thus enabling…

Guide to Road Design Part 4A: Unsignalised and Signalised Intersections provides road designers and other practitioners with guidance on the detailed geometric design of all at-grade intersections (excluding roundabouts). This Part contains…

Guide to Road Design Part 4C: Interchanges provides guidance on the geometric design of interchanges on freeways/motorways and on major arterial roads. The Guide covers the design of interchanges between freeways and arterial roads

This report documents the best practice approaches for the use of road tunnel wall panels and finishes, which informed the development of a specification framework. This was developed through a workshop with subject-matter experts, review of current…

This report, originally published in November 2021, outlines the findings of a project to develop clearer and more consistent tunnel signage to reduce the impact of over-dimensioned and dangerous goods vehicles on both infrastructure and Workplace…

Road tunnels are an important element of the transport infrastructure, requiring significant resources and energy to construct, operate and maintain. Consequently, they are potentially a major source of greenhouse gas emissions and environmental…
