Attachment 5 - Traffic Impact Assessment Final PTT · 132005.638.06

TRAFFIC IMPACT
A traffic impact assessment has been undertaken in accordance with TMR’s Guide to Traffic Impact
Assessments. The main points to note are:

—      the proposal is expected to increase traffic by 34vph and 34vph in the Tuesday and Sunday peak
       hours, respectively
—      the results of the intersection analysis indicate that the Eumundi Noosa Road / Site Access priority-
       controlled intersection is expected to experience LOS A operations during the Tuesday and Sunday
       peak hours under 2028 and 2038 pre and post-development scenarios.
—      the addition of development generated traffic does not warrant mitigation works to be undertaken
       on the state-controlled road network (ie results in a 0.8% increase in average delay for pre-
       development traffic)
—      it is recommended that consideration be given to upgrading the existing CHR(s) on Eumundi Noosa
       Road to a CHR based on the results of a turn warrant assessment
—      the minimum requirements for a CHR on Eumundi Noosa Road (ie 90km/h design speed =
       80km/h speed limit plus 10km/h) consist of the following:

       —       a 75.0m diverge length, including a 25m long taper
       —       a 19.0m storage length to cater for one design turning vehicle (ie AV)

ROAD SAFETY
A road safety assessment has been undertaken in accordance with TMR’s Guide to Traffic Impact
Assessments. The main points to note are:

—      Council has banned right turns at the site exit
—      the risk of angle crashes between through traffic on Eumundi Noosa Road and right-turning
       vehicles from the site access has been mitigated
—      proposed development is not expected to increase the risk score of the state-controlled road
       network
