Note:   CHR(S)     = Channelised Right Turn Treatment with reduced length


Based on the results illustrated in Table 4-4, the following turn treatments are therefore
warranted for the 2022 scenario:

         
       Right Turn: CHR standard.

Notwithstanding the above, the existing BAR type of geometry for the Cooroy-Noosa Road /
Carramar Access / Access to Local Development intersection would provide satisfactory
operation for the proposed redevelopment of Carramar Aged Care Facility from a capacity point
of view. However, from the findings in Table 4-4 above, from a safety point of view (as indicated
ablove), the design of the Cooroy-Noosa Road / Carramar Access / Access to Local
Development intersection would be recommended to be of a type CHR standard.

The proposed new layout of the Cooroy-Noosa Road / Carramar Access / Access to Local
Development intersection, modified to comply with current standards (with a type CHR
standard), is shown in Figure A1 within Appendix A.


4.2 Proposed Cooroy-Noosa Road / Carramar Access
    / Access to Local Development Intersection
As requested by Council within the Noosa Council Conditions dated 16 November 2007
regarding roadworks widening (item 17), “The existing intersection at Cooroy Noosa Road shall
be upgraded, at no cost to Council, to AUSTROADS – CHR standard, including median island,
separate right turn lane, and the necessary pavement widening prior to the commencement of
the next stage. In this regard, plans detailing this work shall be prepared and submitted to
Council for approval prior to obtaining a Development Permit for Operational Works.”

An assessment of the proposed Cooroy - Noosa Road / Carramar Access / Access to Local
Development intersection has therefore been undertaken utilising traffic engineering package
SIDRA5.0.

A SIDRA generated schematic illustration of the proposed access intersection (with a CHR) is
shown as Figure 4-3.
