Traffic Generation
Existing Centre
Cardno has previously undertaken several traffic studies for the Noosa Civic Shopping Centre including a
comprehensive traffic survey, parking demand assessment and detailed traffic capacity impact assessment of
current uses.
In order to determine the traffic generation potential of the existing Noosa Civic site, traffic counts were
performed on each of the entrances to the site on 31 July 2014 and 2 August 2014, in addition to counts
performed on the surrounding road network. Comparing these counts to the centre size would give a
representative traffic generation of the site for a given day in July/August.
To consider the seasonal fluctuations of the Noosa Civic site, Cardno has reviewed the daily door count data
for Noosa Civic for the year of 2013. Using this data, the average trading volume for Thursdays and Saturdays
in July/August was compared to the yearly 85th percentile trading volume on Thursdays and Saturdays.
From the analysis of the door count information, a factor was devised to apply to traffic counts taken at Noosa
Civic, in order to determine an 85th percentile traffic generation for the existing Noosa Civic. The 85th
percentile traffic generation of the existing Noosa Civic is shown in Table 1.
Table 1 summarises the traffic generation for the existing centre. As shown, the Noosa Civic Shopping Centre
was calculated to generate 2,123vph in the Thursday peak hour and 2,223vph in the Saturday peak hour on
the 85th percentile trading days.

To obtain an estimate of the daily profile of visits to and from the centre, the data provided from Google
analytics was retrieved. This is illustrated on Figure 2.
