            representation of individual roads. Extending this value across the entire network is therefore
            considered to be appropriate.

4.6         Traffic
            “Council has observed many two-lane roundabouts within the coastal road network at which
            actual queue lengths do not match modelled queue lengths (from programs such as SIDRA). This
            is considered to be primarily due to upstream departure issues.

            Information Required:
            43   Amended SIDRA analyses of existing and projected traffic volumes calibrated against
                 observed queue lengths, particularly at the more critical intersections. The queue
                 length measurements should be based on individual approach lanes and traffic
                 counts should be lane-specific because it is likely that lane utilisation is not optimal
                 because of upstream and downstream intersection issues.”
            RESPONSE
            The SIDRA computer analysis package is a recognised and industry accepted analysis tool that
            does not require calibration against local conditions.
            SIDRA is considered an appropriate assessment and analysis tool because it uses the same
            adopted parameters for the base case and with-development traffic scenarios. This allows for
            direct assessment of the development traffic impacts.
            The traffic analysis which was provided with the development application is considered sufficient
            to identify traffic impacts at the relevant intersections with and without development traffic. As
            such, Noosa Shire Council has been provided with sufficient information to consider and assess
            development traffic impacts.
            Please refer to Appendix D – Traffic and Transport Response.

4.7         Traffic
            “Traffic volumes on the Noosa coastal road network significantly increase during holiday periods,
            roughly corresponding with school holiday periods. Consequently, traffic assessments over a long
            period of time have been based on desirable maximum roundabout degrees of saturation during
            non-holiday periods being 0.70 (rather than 0.85) to allow tolerable traffic congestion during peak
            holiday periods.

            Information Required:
            44   The analyses submitted should include assessments of intersection performance
                 during peak holiday periods.”
            RESPONSE
            Traffic capacity analysis during holiday periods is not considered to be a necessary or reasonable
            impact assessment for conventional developments, such as the one proposed by the Applicant.
            The traffic analysis which was provided with the development application is considered sufficient
            to identify traffic impacts at the relevant intersections with and without development traffic. As
            such, Noosa Shire Council has been provided with sufficient information to consider and assess
            development traffic impacts.
