2.4 Existing Access Intersection Performance
An intersection capacity analysis has been undertaken at the Cooroy-Noosa Road / Carramar
Access / Access to local development intersection for the 2010 existing traffic situation utilising
traffic capacity analysis software SIDRA 5.0.

The outputs of the SIDRA 5.0 analysis are provided within Appendix D of this report. The
operational performance of the intersection for the 2010 existing conditions is summarised in
Table 2-1.

Note: Practical Maximum Degree of Saturation (Xp) for unsignalised intersection is 0.80.


As shown on Table 2-1 above, the Cooroy-Noosa Road / Carramar Access / Access to local
development intersection operates well within acceptable limits with the existing facility and
current intersection layout.
