Methodology for Comparing Dangerous Goods Risks in Road Tunnels to Those on Alternative Routes: Best Practice Review
  • Publication no: AP-R703-24
  • ISBN: 978-1-922994-20-2
  • Published: 24 January 2024

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) materials.

This report reviews best international practice in road tunnel DG risk assessment and provides justification for the selection of a Dangerous Goods Quantitative Risk Assessment Model (DG-QRAM) as the tool most appropriate for comparative DG risk assessments.

The second report AP-R704-24 Methodology for Comparing Dangerous Goods Risks in Road Tunnels to Those on Alternative Routes: Manual for Using DG-QRAM in the Australasian Context provides background on the development, capabilities and limitations of the DG-QRAM tool as well as guidance as to how the DG-QRAM tool should be applied to road tunnels in Australia and New Zealand.

The third report AP-R705-24 Methodology for Comparing Dangerous Goods Risks in Road Tunnels to Those on Alternative Routes: Case Study Using DG-QRAM in the Australasian Context illustrates the stages of the comparative assessment, with incorporation of mitigation measures. The case study is a demonstration of the intent of the method that is detailed in the manual.
