Response to Sunshine Coast Regional Council Information Request

3.2 Intersection Analysis
The intersections have been analysed using SIDRA Intersection 3.2 for the 2022 design
year, for both background traffic (without development) and design traffic (with
development). Comparison of these two scenarios will determine the impact the
development will have on the local traffic network. It has been assumed that the layout of
the intersections will remain unchanged from 2008 to 2022.
The results of the SIDRA analysis the intersections being considered have been
summarised in tabular form below. Each table makes reference to three intersection
performance criteria. A description of each follows:
Degree of Saturation (%) — This is the ratio of demand flow to capacity.
Average Delay (sec) — The average delay per vehicle in seconds incurred by vehicles over
the modelled time period.
95" %ile Queue—A queue length measured in metres for which only 5% of queues are
equal to or greater than this length.
Sunshine Coast Regional Council has specified that roundabouts in the Noosa region
require a maximum degree of saturation of 0.7. Whilst this is an unusual request, it has
been taken into account in our analysis.
