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 summarises the findings of a review of current practices relating to speed information management (i.e. speed limits and operating speeds) in Austroads jurisdictions. As speed information management is an emerging topic, current…

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…

The Austroads Road Authority Data for Connected and Automated Vehicles (RADCAV) project studied the provision of agency-owned data to connected and automated vehicles (CAVs) addressing six high-priority data sets: roadworks, incidents, variable…

These eight reports provide guidance on the provision of agency-owned data to connected and automated vehicles (CAVs). Six high-priority data sets are addressed: roadworks, incidents, variable speed limit signs and lane control signals, static speed…

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…

The Guide to Road Safety Part 3: Safe Speed provides an overview of speed limits and their application as a speed management tool.
