MYALL STREET / ELM STREET INTERSECTION

We have obtained morning and evening peak hour traffic counts at the Myall Street / Elm Street

intersection undertaken in 2012 from DTMR. These traffic counts found peak hour volumes as follows:

m= 2012 Morning Peak: 2,100 vehicles per hour
m= 2012 Evening Peak: 2,770 vehicles per hour

We have made the assumption that 85% of the total development generated traffic arriving and departing
to the north would travel through this intersection. This estimate is based on approximately 5% of traffic
arriving and departing to / from the north using Ferrells Road (as observed in the traffic surveys of the
Myall Street / Ferrells Road intersection), with the same proportion of traffic assumed to use Tulip Street

and Crystal Street to access the west of Cooroy.

On this basis it is estimated that the development would increase traffic flows at this intersection by less
than 2% in the evening peak hour and would not exceed 5% on any individual turning movements.

Therefore, in accordance with GARID, no further assessment of this intersection has been undertaken.

INTERSECTION OPERATIONS

A series of SIDRA analyses have been conducted for the following intersections:

== _— Myall Street / Site Access priority intersection
== Myall Street / Ferrells Road priority intersection
== Myall Street / Bruce Highway Ramps priority intersection

These were based on the turning movement forecasts presented in Appendix D for the following

scenarios:

Existing year (2014)

Opening year (2017) pre-development
Opening year (2017) post-development
Future year (2027) pre-development

Future year (2027) post-development

The SIDRA analyses were based on the traffic count data presented in Appendix C with:

== gap acceptance parameters as per Table 13.7 of the DTMR RPDM and identified for each
intersection below

== proportion of heavy vehicles (%HV) as identified in the traffic surveys

m= Peak Flow Factors (PFF) as calculated from the traffic surveys

m= SIDRA default values for other parameters
