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…

This report documents a project undertaken to investigate the issues associated with managing the planning, construction, operation and maintenance of road tunnels in a sustainable manner. The results of the investigation informed an update to all…

Road tunnels are major pieces of infrastructure across the road network, and the number of tunnels is expected to increase in the coming years. Although they are relatively safe, a significant number of crashes occur on the approaches to and within…

This report evaluates selected low-cost perceptual countermeasure (PCM) treatments in tunnel environments. PCM treatments are used to reduce crash risk by improving driver speed behaviour, alertness and lane discipline within tunnels. Two key…

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…

This webinar, presented by Les Louis, Lauren Thompson and Dr Richard Yeo, informs practitioners about the updates made to Part 2 of the Guide to Road Tunnels in 2021 and the reasons for those changes. Every section of Part 2 is addressed to show…

Guide to Road Design Part 3: Geometric Design provides road designers and other practitioners with information about the geometric design of road alignments.

Guide to Road Design Part 6A: Paths for Walking and Cycling provides guidance for designers and other practitioners on the design of paths for safe and efficient walking and cycling, both within the road corridor and outside the road corridor. The…
