        4.4.2 Maple Street / Overlander Avenue

        The analysis of the Maple Street / Overlander Avenue priority-controlled intersection was
        undertaken using the SIDRA intersection representation shown in Figure 2.6. The results of the
        analyses are attached in Appendix C and summarised in Table 4.4. As demonstrated, the
        intersection 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
        intersection operations.

        The reduced average delay under 2023 post-development conditions in the afternoon peak hour
        is due to the increased volume of through vehicles (which experience no delay) at the intersection.
