Austroads has recently completed a project to identify best practice for road tunnel wall panels and finishes to ensure the products achieve performance, access, maintenance, and durability requirements. The best practice research provided through…

Austroads has recently completed a project to identify best-practice guidance for the design, delivery and testing of in-tunnel aesthetic design features, with the aspirations to improve tunnel safety and customer experience. Through the review of…

This report documents the best practice approaches for the use of road tunnel wall panels and finishes, which informed the development of a specification framework. This was developed through a workshop with subject-matter experts, review of current…

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…
