5.0      ROAD SAFETY ASSESSMENT

5.1      REQUIREMENT
         TMR’s GTIA requires a risk assessment of the likelihood and consequence of safety risks being
         increased on the state-controlled road network due to the development generated traffic. A risk
         assessment has been undertaken using the methodology prescribed in Section 9.3.2 of TMR’s
         GTIA, to assess the potential impacts of the proposed expansion on the safety of the Eumundi
         Noosa Road / Site Access intersection.

5.2      METHODOLOGY
         The risks inherent on the existing state-controlled road network and associated with the addition
         of development generated traffic were scored using the risk scoring matrix outlined in TMR’s
         GTIA, as reproduced in Figure 5.1. In undertaking the risk assessment:

         —        the likelihood of a crash was determined based on the number of similar crashes reported
                  in the historical crash data
         —        the consequence of a crash was based on the Killed or Serious Injury (KSI) Indexes reported
                  in Part 4 of TMR’s Manual of Uniform Traffic Control Devices (MUTCD) for different crash
                  types / DCA Codes

5.3      CRASH DATA
         Historic crash data supplied by TMR has been reviewed for Eumundi Noosa Road / Site Access
         priority-controlled intersection for the past five years (ie July 2020 to June 2025). This data
         indicates that no crashes were recorded over the five-year period.

         However, Council has advised that four crashes have been recorded between March 2025 and
         June 2026, all involving angle crashes between through traffic and right-turning vehicles from
         the site access (ie DCA Code 104). This indicates that there may be safety issues at this
         intersection.
