This webinar, the first in a four-part series, provides an overview of a project to update Austroads intersection design guidance, including the aim, research background, methodology and outcomes. The session outlines the new concepts and content…

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 details a trial conducted to evaluate whether a suitable road-based perceptual countermeasure (PCM) could influence the travelling speed as well as lane position of motorcyclists to induce a safe curve negotiation. The motorcyclist PCM…

Practitioners have raised concerns when designing for heavy vehicles with respect to the combination of design values for side and longitudinal friction demand as well as design criteria for horizontal curves with adverse superelevation. This report…

Road Authorities, practitioners and other stakeholders have identified minor editorial issues within the Austroads Guide to Road Design (GRD) Part 3 that result in possible ambiguity or inconsistency within the Guides to Road Design Series. A total…
