The analysis indicates that, provided the intersection is signalised (by others), the Elm Street /
Diamond Street intersection will function at a satisfactory degree of saturation into and beyond
the planning horizon year of 2019 with the combined base traffic volumes and those of the
ultimate development proposal.

It should be noted that the traffic generated by the proposal appears to have a minimal impact
on the operation of the intersection, as it only results in an increase in the maximum degree of
saturation of 0.02 for the critical movement over the base case for the 2019 scenario. This is a
reflection that the development represents less than 5% of the traffic through the intersection.
Therefore, no works are required at this intersection as a consequence of the development.

5.2.2 Elm Street / Pearsons Road Intersection
The results of the traffic analysis for the 2019 scenario including both base traffic and traffic

generated by the proposed development are presented in Table 9. The intersection Movement
Summary data (from SIDRA3.2) are provided in Appendix C.

Note: Practical Maximum Degree of Saturation (X,) for unsignalised intersections is 0.80.

The analysis indicates that introduction of the traffic generated by the proposed development will
have minimal impacts on the capacity or operations of the intersection of Elm Street and
Pearsons Road following implementation of the ultimate development by 2019, provided the
recommended intersection improvements are undertaken (i.e. construction of a right-turn bay
from Elm Street into Pearsons Road as shown on Figure A2 within Appendix A of this report).
