5.0 DEVELOPMENT TRAFFIC IMPACTS

5.1 Assessment Scenarios

The impact of the proposed development on the operation of the following intersections has
been assessed:

. David Low Way/Heron Street/hotel access;
. David Low Way/unnamed access road.

The above intersections have been assessed for the following design traffic scenarios:

. 2008 background traffic volumes;
. 2018 background traffic volumes;
. 2008 post development traffic volumes;
. 2018 post development traffic volumes.

The methodology for calculating the background traffic volumes and traffic generated by the
proposed development are set out in the following sections.

It is noted that the traffic surveys at David Low Way/unnamed access road included traffic
generated by the current operation of the site. This traffic has not been removed from the
background traffic counts. As such, the following traffic impact assessment is considered
conservative.

5.2 Traffic Growth

In order to predict the future background volume of traffic at the abovementioned intersections
without the proposed development, a linear growth rate of 5% has been applied to the existing
traffic volumes at the intersections. This growth rate is at the higher end of the typically
adopted range which considered a conservative approach. This is to account for further
anticipated development of the Peregian Beach Village.

The calculated background traffic volumes at 2018 are shown on Figure 5.1.
5.3 Traffic Generation

To determine the peak hour traffic generation of the proposed development, reference has
been made to the draft ‘Transport Assessment Guide’, prepared by Eppell Olsen and Partners
for the Department of Main Roads. The traffic generation rates adopted and the resultant
traffic generation for the proposed development are set out in Table 5.1.
