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…

Two parts of the Austroads Guide to Project Delivery &ndash

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…

Guide to Project Delivery Part 2: Planning and Control gives guidance to project delivery practitioners on a number of concepts relating to planning and control of the delivery phase, as opposed to the preceding initiation phase and subsequent…

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…

A recently completed project has recommended changes to the Austroads Guide to Road Tunnels Part 2: Planning, Design and Commissioning to provide guidance on rationalising road signs on the approaches to tunnels, to divert over-height and dangerous…

This webinar, 

Austroads commissioned this study to investigate the current challenges and issues affecting the delivery of transport infrastructure projects and the consequential impacts on value for money, timeliness of delivery, agency and political reputation.…

This webinar, presented on 12 September 2019, provides an overview of an Austroads project that examined the passage of dangerous good through Australasian road tunnels, and continuing studies on this topic.
