4.4     Intersection Performance

        The likely impact of the proposed expansion on the peak hour operations on the surrounding road
        network has been assessed using SIDRA. These analyses are based on the peak hour turning
        movement forecasts presented in Appendix D.

        4.4.1 Cooroy Belli Creek Road / School Access

        The analysis of the Cooroy Belli Creek Road / School Access priority-controlled intersection was
        undertaken using the SIDRA intersection representation shown in Figure 2.5. The results of the
        analyses are attached in Appendix C and summarised in Table 4.3. As demonstrated, the access
        is expected to experience LOS A operations during the weekday morning and afternoon peak
        hours, under 2023 and 2033 pre and post development scenarios. The addition of development
        generated traffic is not expected to have a significant adverse impact on the access operations.
