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 one 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.
