            The analysis indicates that the roundabout is expected to operate at suitable levels at the during the 2025
            assessment year, with earthworks traffic included, with a worst-case DOS 44% (less than 85%, practical
            capacity limit of roundabout) and overall LOS A. The addition of the Bulk Earthworks traffic has no notable
            impact to key operational metrics, with minor change to average intersection delay and at most an increase
            in queuing of 1 m (less than 1 vehicle length – approx. 6.0m).

            Based on this SIDRA capacity assessment, the proposed Bulk Earthworks traffic generation is considered to
            have negligible impact on the operations of the Noosa Drive / Coral Tree Avenue roundabout intersection.

                      Analysis of Grant Street / Noosa Drive / Sunshine Beach Road

            Figure 3-2 overleaf shows the configuration of the Grant Street / Noosa Drive / Sunshine Beach Road
            roundabout intersection adopted in the SIDRA analysis. All default SIDRA inputs were used for the analysis.
