9.3        Assessment Scenarios
9.3.1      Assumptions
For the purpose of the traffic assessment conducted herein, the year of opening of the
proposed development has been assumed to be 2027. A 10-year design horizon of 2037 has
therefore been adopted.
Importantly, Stockwell has advised that it is unlikely that the balance land throughout the
Noosa Business Centre will have been developed within the 2037 design horizon. For the
purposes of this assessment, the analysis has assumed that the Noosa Business Centre is
fully developed in order to demonstrate that the key internal intersections will operate
satisfactorily in this circumstance.

9.3.2      Assessment Scenarios
Reflective of the above assumptions, the performance of the road network was considered for
the following scenarios:
       2022 Baseline: To establish existing operational conditions.
       2027 Baseline: To establish the operational performance of the road network in the
        absence of the development at the year of opening, including the surrounding
        development potential within this design year for the Noosa Business Centre.
       2027 Baseline with Development: To identify the impact of the traffic generated by the
        development at the year of opening.
       2037 Baseline: To establish the operational performance of the road network in the
        absence of the development at the 10-year design horizon. including the surrounding
        development potential within this design year for the Noosa Business Centre.
       2037 Baseline with Development: To identify the impact of the traffic generated by the
        development at the 10-year design horizon.
The operation of the road network was assessed for all the above scenarios during the
Thursday PM and Saturday midday peak hours.

9.4        Intersection Assessment
9.4.1      I1: Hofmann Drive / Noosa Civic Access Road
The Hofmann Drive / Noosa Civic Access Road is an existing 3-leg roundabout intersection.
The existing layout and SIDRA assessed intersection form are shown on Figure 8 below. The
results of the SIDRA assessment are presented in Table 20 below. Detailed SIDRA outputs
are provided at Appendix E.
