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 details research into the ways transport agencies manage unplanned incidents that impact the normal operation of more than one transport mode. It includes 10 guiding principles and a capability framework. Road agencies need guidance on…

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 report documents the extensive reviews and evaluations of established and emerging methodologies in Freeway Capacity Analysis. It also documents the extensive consultations with Australian and New Zealand practitioners to capture their current…

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.

The 2016 Austroads Congestion and Reliability Review (AP-R534-16) measured the levels of congestion across major cities in Australia and New Zealand, assessed the key causes of congestion, and proposed an approach to identifying and assessing…
