6           Traffic Impact Assessment
6.1         Estimated Development Traffic Generation and Distribution
The NSW RTA, Guide to Traffic Generating Developments, recommends using specific generation rates for
planning purposes and has been used as the basis of this assessment. Application of these rates to the
existing and proposed development is provided below:

•    Weekday peak hour vehicle trips = 0.65 per dwelling

The proposed development traffic equates to 35vph (in+out).

The inbound / outbound distribution of development traffic is based on the following:

•    20% of development traffic is inbound in the AM Peak, with the remaining 80% outbound

•    80% of development traffic is inbound in the PM Peak, with the remaining 20% outbound

6.2         Potential Traffic Impacts
Based on this distribution, the development is expected to generate 28 outbound vehicles and 7 inbound
vehicles in the AM peak hour. Note that the inbound/outbound distribution will be reversed in the PM peak
hour. This generation equates to approximately 1 vehicle entering or exiting the site every 2 minutes during
the peak hour periods.

This increase in traffic is not considered to significantly impact the operation of the external road network
given that it will distribute between all directions once arriving at the Eumundi Noosa Road / Goodchap
Street roundabout and further into the local road network. Therefore, a detailed assessment is not
considered to be warranted.
