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

  •     High – should be corrected or the risk significantly reduced, even if the treatment cost is high.
  •     Extreme – should be corrected regardless of cost.
  No definitive guidance can be given as to the respective monetary values of the terms ‘low’, ‘moderate’ or
  ‘high’ regarding treatment costs, but it is expected that consideration against the total project cost (or total
  benefit) would be an important factor when categorising mitigation of each risk.



  4.3 Recommendation Hierarchy
  When considering the recommendations related to each road safety issue identified in this RSA, the audit
  team has determined this in a manner which aligns with the Safe System philosophy. The audit team has
  generally followed the treatment category/hierarchy as detailed in Figure 5.3 of Austroads GRS Part 6. This is
  replicated in Table 4.4.

  Table 4.4: Safe System Treatment Category / Hierarchy

      Treatment Category              Description

      Primary Treatment               Road planning, design and management considerations that practically eliminate the
                                      potential of FSIs occurring in association with the foreseeable crash types.

      Supporting                      Road planning, design and management considerations that improve the overall level of
      (Step Towards)                  safety associated with foreseeable crash types, but not expected to virtually eliminate
                                      the potential of FSIs occurring.

                                      However, this treatment improves the ability for a Primary Treatment to be implemented
                                      in the future.

      Supporting Treatment            Road planning, design and management considerations that improve the overall level of
                                      safety associated with foreseeable crash types, but not expected to virtually eliminate
                                      the potential of FSIs occurring.

                                      This treatment does not change the ability for a Primary Treatment to be implemented in
                                      the future.

      Non-Safe System                 Road planning, design and management considerations that are not expected to achieve
      Treatment                       an overall improvement in the level of safety associated with foreseeable crash types
                                      occurring.
      Other Elements
                                      Reduces the ability for a primary treatment to be implemented in the future.
