3.6 Year 2015 capacity analysis – Cooroy
Capacity analysis under existing conditions indicates degrees of saturation (DOS) at strategic
intersections within the Cooroy area at peak times as depicted in Figure 11.




Figure 11: Year 2015 AM and PM peak hour Degrees of Saturation at Cooroy

The critical traffic related issues in this part of the network are:

(i)         Myall St / Elm St intersection
(ii)        Diamond St / Elm St intersection

The Myall St / Elm St intersection is operating way over capacity. The only way this
intersection conveys the volume of traffic that it does from Myall St (south) into Elm St (east) is
due to the low speed environment and the courtesy of other drivers using the intersection. This
intersection is part of the State-controlled road network and negotiations have commenced with
DTMR in relation to its upgrading.

The Diamond St / Elm St intersection is almost at absolute capacity, with there being issues
turning right from Diamond St into Elm St (north) in the afternoon peak. This intersection is
also part of the State-controlled road network and negotiations have commenced with DTMR in
relation to its upgrading.
