F - Traffic Response and Revised Traffic Impact Assessment (17.09.19)

20 Hofmann Drive, Noosaville | Traffic Impact Assessment


9.0 Traffic Volumes
9.1 Surveyed Traffic Volumes
Austraffic were commissioned to undertake traffic volume surveys at the following intersections (study
intersections):
    • Hofmann Drive / Noosa Civic Access / Site Access
    • Hofmann Drive / Noosa Civic Access
    • Eenie Creek Road / Hofmann Drive
    • Eenie Creek Road / Walter Hay Drive

Surveys were undertaken on the Thursday 1st and Saturday 3rd of August 2019.

A copy of the traffic survey data is included in Appendix E.

The surveys indicated that the observed adjacent road network peak hour periods were:
    • Saturday Noon / AM – 11:15am – 12:15pm; and
    • Thursday PM – 3:00pm – 4:00pm.

These peak hours have been adopted for the traffic assessment. These peak hours are also reflective of
that adopted for the previously completed traffic assessments (Previous Approval).


9.2 Background Traffic Growth
In order to identify future background traffic volumes, the following compound growth rates were
applied to the surveyed traffic volumes:
    • Eenie Creek Road – 1.8% p.a.; and
    • Local road network – 0.5% p.a.

The background traffic growth rate adopted for Eenie Creek Road has been based on the DTMR census
data for the closest count site (Segment Site 20032 Eumundi Noosa Road). The adopted background
traffic growth rate for the local road network was identified based on a review of Noosa Shire Council
Local Government Infrastructure Plan (LGIP) population growth estimates for Noosaville (i.e. 0.3% p.a.).
