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 method describes the procedure for obtaining a measure of the evenness of a pavement surface as determined by the deviation from a three metre straightedge. It is applicable only to the measurement of depressions in the pavement surface and to…

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 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.

This report provides a standardised assessment method to mitigate the criticism of the transport of dangerous goods through road tunnels and provide greater transparency of the decisions reached. The transport of dangerous goods is critical to…

This report documents the results of an extensive literature review examining the transport of dangerous goods in road tunnels. It includes international and local studies and methodologies, trial reports, and media. The transport of dangerous goods…

This report sets out the process though which fire incident and fire safety operational information was collected for eleven major road tunnels in Australia. This tunnel data set are the major tunnels in Australia as defined by physical…
