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…

Road authorities, practitioners and other stakeholders have identified minor editorial issues within the Austroads Guide to Road Design (GRD) Parts 4, 4A, 4B and 4C that result in possible ambiguity or inconsistency within the Guides to Road Design…

Austroads has recently completed a project to consolidate the previous Guide to Road Design Part 1: Introduction to Road Design, Part 2: Design Considerations and Part 8: Process and Documentation into a new Part 1: Objectives of Road Design. This…

Guide to Road Design Part 7: New and Emerging Treatments contains design-related knowledge, findings from research and practical experiences about new and emerging treatments.

Raised Safety Platforms (RSPs) are a vertical deflection device increasingly used to reduce the maximum comfortable operating speed for vehicles to Safe System collision speeds, particularly at intersections. While the use of vertical deflection…

Austroads has recently completed a project to review and propose improvements to the guidance on interrupted traffic flow theory contained within the Austroads Guide to Traffic Management (AGTM), Part 2 and Part 3. The updates will broaden…
