This report outlines a detailed and contemporary review of in-tunnel aesthetic features applied and tested, and how such features can be considered throughout the project lifecycle: planning, design, procurement, operation, maintenance, testing and…

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…

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…

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, presented on 29 April 2020, discusses the merits of three options to advance the future of PBS access in Australia as it relates to bridges. The webinar explains the role that PBS bridge formulae play in vehicle design and approval. It…

The May 2018 National Transport Commission review of the Australian Performance-Based Standards (PBS) scheme revealed the need to improve the efficiency of heavy vehicle access via the PBS scheme to access substantial national freight productivity,…

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.
