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

The analysis indicates that, in 2009, the intersection of Elm Street / Diamond Street will continue
to function within an acceptable degree of saturation in both the AM and PM peak periods with
the addition of traffic generated by the proposed development.

5.1.2 Elm Street / Pearsons Road

The traffic distribution for the proposed development (discussed in Section 3.6) indicates that the
northbound right-turn movement at Pearsons Road was estimated to be approximately 55
vehicles, with an opposing through volume of approximately 550 vehicles in the AM peak hour.
Likewise, the northbound right-turn volume was estimated to be 67 vehicles with an opposing
volume of approximately 402 vehicles in the PM peak hour. According to the Department of
Main Roads’ “Road Planning and Design Manual”, Chapter 13, Figure 13.21, these volumes
warrant a separate right-tum bay from Elm Street into Pearsons Road. A functional layout of the
Elm Street / Pearsons Road intersection, including the recommended right-turn bay, has been
included as Figure A2.

The results of the traffic analysis for the 2009 scenario, including the base traffic, the traffic
generated by the proposed development and including provision of a right-turn pocket, are
presented in Table 7. The SIDRA3.2 Movement Summary output data sheets for the analysis
are provided in Appendix C.

A SIDRA generated configuration of the proposed upgrade is shown as Figure 5.
