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…

Physical road infrastructure such as pavement markings and signals may have an important role to play to support the uptake of automated vehicles (AVs). Austroads has recently completed a project to provide road agencies with clear advice on…

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…

These reports provide guidance on infrastructure investment to help transport agencies achieve timely, consistent and adequate infrastructure readiness for the operation of current and future automated vehicles. Physical road infrastructure such as…

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 user guide provides guidance on the Investment Prioritisation Templates. The templates are designed to help road authorities consider an investment opportunity through multiple dimensions, such as the benefits of the project, and risk with and…

Currently road authorities rely on multiple different decision making-frameworks to help identify investment opportunities for the road network. The framework used often varies depending on the nature of the expenditure. For example, cost benefit…
