This webinar presents the work involved in developing a standardised comparative risk assessment method for assessing life safety risk of dangerous goods being routed through the tunnel or via an alternative surface route.

This report is one of the three reports produced as part of a project undertaken to establish a comparative risk assessment method for assessing whether a tunnel route is safer than a surface route for the road transit of dangerous goods (DG)…

This report is the second of the three reports produced as part of a project undertaken to establish a comparative risk assessment method for assessing whether a tunnel route is safer than a surface route for the road transit of dangerous goods (DG)…

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…

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…

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…
