of 0.85 and 0.94 in the 2036 AM non-holiday and holiday peaks (when metering would be
operational), and 0.78 and 0.83 in the PM non-holiday and holiday peaks (when metering would
not be operational). It is noted that degrees of saturation in excess of the normal 0.85 practical
limit at roundabouts is acceptable when the roundabout is metered because the queues and
associated delays are then much better managed.



5.2.5 Year 2036 – Butler St / Poinciana Ave

By 2036, with the existing intersection configuration, the Butler St / Poinciana Ave intersection
is predicted to be operating with a degree of saturation of 0.89 in the morning non-holiday
period and 1.00 in the morning holiday period. Sufficient additional capacity would be
achieved, to satisfactorily accommodate year 2036 traffic projections, by upgrading the
roundabout by means of provision of a short additional left turn lane on the northern Butler St
approach.

With those improvements, the intersection is predicted to operate with a degrees of saturation
in the critical AM peak hour period of 0.69 and 0.73 in the 2036 non-holiday and holiday peaks.



5.2.6 Year 2036 – Gibson Rd / Eumundi Noosa Rd

By 2036, with the existing intersection configuration, the Gibson Road / Eumundi Noosa Road
intersection is predicted to be operating with a degree of saturation of 0.82 in the afternoon
non-holiday period and 1.00 in the afternoon holiday period. Sufficient additional capacity
would be achieved, to satisfactorily accommodate year 2036 traffic projections, by upgrading
the roundabout through provision of a short additional lane (with storage of about 40m) on the
eastern Gibson Rd approach, so that there would be full left turn lane and a short through/right
turn lane on that approach.

With those improvements, the intersection is predicted to operate with a degrees of saturation
of 0.44 and 0.53 in the 2036 AM and PM normal peaks, and 0.54 and 0.63 in the AM and PM
holiday peaks.



5.2.7 Year 2036 – Eumundi Noosa Rd (Beckmans Rd to Goodchap St)

To achieve sufficient capacity on Eumundi Noosa Road, with maintenance of the existing free
flowing roundabout based network, to accommodate growth to the year 2036 with the approved
“Masters Home Improvement” and 12,000 sq m of additional office GFA at the Shire Business
Centre, the following would be required:

(i)         Minor upgrading of the Eumundi Noosa Rd / Goodchap St intersection through
            alteration to existing line marking to achieve a dual right turn from Goodchap St into
            Eumundi Noosa Rd (south).

(ii)        Provision of a separate left turn lane in Eumundi Noosa Road on the southern
            approach to the Eenie Creek Rd intersection.
