were   then adjusted to reproduce the level of queuing on the Woodland Drive leg. A Critical Gap value in excess

of 7 seconds was required in order to obtain similar queuing to that observed in the traffic surveys. As this is an

unrealistically high value, the parameters detailed in Table 13.7 of Main Roads’ Road Planning and Design
Manual were used instead.


As per the assumptions in the submitted Traffic Impact Assessment, the following development staging has been

adopted:

-        Traffic Counts:                                   2013

-        Development Application:                          2013

-        Construction and Full Occupation:                 2015

-        Occupation plus 10 years:                         2025


A background traffic growth rate of 1.8% per annum has been adopted, as sourced from the Department of Local

Government and Planning (DLGP)Population Forecasts.




Davjd Low Way / Woodland Drive Intersection


In all the pre-development scenarios, the Woodland Drive approach has been modelled           on   the basis of the

existing configuration with a single approach lane from the west. However, to improve the capacity of the
intersection for the post-development scenarios, it is recommended that separate right and left turn lanes be

provided for the first 18m of Woodland Drive. This intersection upgrade would help address the traffic impacts
generated by the proposed development. On site observations suggests that there is sufficient carriageway width
to   provide two lanes without any widening. Figure 5 demonstrates the upgraded intersection layout analysed in
the post-development scenarios.
