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 outlines a detailed and contemporary review of in-tunnel aesthetic features applied and tested, and how such features can be considered throughout the project lifecycle: planning, design, procurement, operation, maintenance, testing and…

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 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 provides information about the design, construction and maintenance of 122 road tunnels in Europe, Asia, North and Central America, Australia and New Zealand.

The project was designed to assemble information on the construction and…

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…
