3.2.4 Year 2015 – Memorial Ave / Doonella St intersection

The Memorial Ave / Doonella St intersection is approaching its 0.85 DOS limit during the AM
peak. This is on the western Doonella St approach to the intersection, and is due to the high
volume on that approach having to give way to the moderate volume of traffic that moves north
through the roundabout on Memorial Ave, and turns right into Lake St.



3.2.5 Year 2015 – Eumundi Noosa Road

Eumundi Noosa Road between Beckmans Road and Goodchap Road is a four lane divided
urban arterial road having dual lane roundabouts along its length. The roundabouts are
currently operating with degrees of saturation at the weekly peaks as follows:

      Beckmans Rd                  0.76
      Rene St / Gateway Dr         0.70
      Eenie Ck Rd                  0.65
      Walter Hay Dr                0.52
      Goodchap St                  0.60

Capacity of the Beckmans Road / Eumundi Noosa Road intersection will be addressed as part
of the DTMR works when duplicating Beckmans Road.

There are opportunities for improving capacity of the existing Eumundi Noosa Road
roundabouts at Eenie Ck Rd, Walter Hay Dr, and Goodchap St. However, there are no obvious
opportunities for improving capacity of the existing Rene St / Gateway Dr / Eumundi Noosa Rd
intersection, which is likely to be the ultimate location of capacity constraint along the Eumundi
Noosa Road route.

Careful management of growth in traffic demands along the Eumundi Noosa Road route
between Beckmans Rd and Gympie Terrace will be required if the free flowing roundabout
based nature of the network is to be maintained. This is discussed in more detail later in this
report.
