5. TRAFFIC IMPACT

The assessment of the impact of the proposed development on the street network has
been undertaken. Traffic volumes have been projected to 10 years past the
completion of development to 2022, assuming the development is operational by 2012
and generating traffic.

5.1 Traffic Impact of the Proposed Development

The impact of the proposed development on the surrounding street network has been
assessed. The development generated traffic has been distributed to the road network
as shown in Figure 4.2 and the operational performance has been analysed according
to the procedures set out in Austroads — Guide to Traffic Engineering Practice.

5.2 Intersection Analysis 2022

Impact on Serenity Close and Banksia Avenue

The adjacent intersections have been reviewed using current guidelines to determine
the operational performance of the intersection in the 10 year planning horizon.
Given the existing residential catchment and the limited potential for future
development in the surrounding streets, traffic growth is not expected to increase
significantly. According to Austroads Part 2 - Roadway Capacity Table 8.1 the
intersection volume below which capacity analysis is unnecessary is as shown below.

Roadway Capacity
Type of Road Light cross & turning volumes
Maximum design hour volumes
Vehictes per hour (two way)
Two Lane major road 400 500 650
Cross road 250 200 100

 

 

 

 

 

 

 

 

 

The forecast traffic volumes for the intersection of Serenity Close and Banksia
Avenue are low and below the volumes stated in the table above, therefore, it is
considered unnecessary to undertake intersection analysis as the intersection operates
with uninterrupted flow conditions (also refer to Table 4.1 Austroads Part 5 —
Intersections At Grade).

Impact on Banksia Avenue Intersections with Grant Street and Katharina Street
Given the above criteria and the traffic volumes generated from the residential
catchment, the above intersections will continue to operate under uninterrupted flow
conditions.
