Response to Further Advice - Road Safety Audit Report 22BRT0122 RSA_2_250722 · OPW25/0042

  4 Road Safety Audit Findings
  4.1 Findings and Recommendations
  A summary of the Road Safety Audit findings along with recommended treatments is provided as appendices
  to this report.

  Appendix A provides the RSA findings table for the intersection.

  Further information is also provided in the following sections to assist with understanding the process used
  in ranking the safety issues identified and providing potential recommended treatments.



  4.2 Risk Assessment Criteria
  The road safety issues identified as part of this audit have been assigned a ranking, as per the methodology
  contained within Austroads GRS Part 6, in order to provide an idea of priority for action. The different ranks
  include:

  •     Negligible
  •     Low
  •     Medium
  •     High
  •     Extreme
  These rankings were determined through a risk assessment, using a combination of crash likelihood and
  severity (i.e. consequence of resulting crash).

  The crash likelihood profile, severity profile and overall risk matrix adopted for the purposes of ranking the
  safety issues is summarised Table 4.1, Table 4.2, Table 4.3 respectively. Once again, these are based
  primarily on the guidance in Austroads GRS Part 6.



  Table 4.1: Likelihood Profiles (as per Austroads GRS Part 6)

      Frequency                              Description
      Almost Certain                         Occurrence once or more per quarter
      Likely                                 Occurrence once per quarter to once per year
      Possible                               Occurrence once per year to once every three years
      Unlikely                               Occurrence once every three years to once every seven years
      Rare                                   Occurrence less than once every seven years
