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, 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…

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…

Practitioners have raised concerns when designing for heavy vehicles with respect to the combination of design values for side and longitudinal friction demand as well as design criteria for horizontal curves with adverse superelevation. This report…

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…

This report provides a compendium of recent and robust evidence on the relationships between twenty key geometric design criteria and safety outcomes.

The project critically reviewed quality research sources to identify crash modification factors…

This report draws on literature and crash data analysis to identify and quantify geometric road design elements which contribute to casualty crash occurrence and severity on rural roads, e.g. lack of sealed shoulders, steep downhill grades combined…

This project forms part of an ongoing Austroads strategic research program to improve the understanding of the relationship between crash risk and road elements. This report provides a summary of the relationship between crash risk, and geometric…
