4.3      TRIP DISTRIBUTION
         The distribution of development-related traffic on the surrounding road network is estimated
         based on the directional splits inherent in the traffic surveys. The resulting distribution of
         development generated traffic is shown in Figure 4.1 for the Tuesday and Sunday peak hours.

         4.4.1        Impact Area
         TMR’s GTIA defines the impact assessment area for intersection delay and road safety as all
         intersections where development traffic exceeds more than 5% of the base traffic for any
         movement in the year of opening (ie 2028).

         The 2028 development generated traffic for the design peak periods (ie Tuesday and Sunday
         peak hours) is only expected to exceed 5% of the base traffic at the Eumundi Noosa Road / Site
         Access priority-controlled intersection, as shown in Appendix F. Therefore, this intersection has
         been assessed further in terms of intersection delay and road safety.

         4.4.1        Site Access Operations
         The likely impact of the proposed expansion on the peak hour operations of the Eumundi Noosa
         Road / Site Access priority-controlled intersection has been assessed using SIDRA. The analysis
         is based on the peak hour turning movement forecasts presented in Appendix F. As discussed in
         Section 2.8.3, the site access no longer allows right-turns out.

         The results of the intersection analyses are summarised in Table 4.4 and attached in Appendix
         D. The results indicate that the Eumundi Noosa Road / Site Access priority-controlled intersection
         is expected to experience LOS A operations during the Tuesday and Sunday peak hours under
         2028 and 2038 pre and post-development scenarios.
