Our Ref: 24S70.1.SAH Date: 21 November 2024 Noosa Council Attention Glen Conforti Dear Sir 62 Lake MacDonald Dr, Cooroy: Traffic engineering assessment of proposal for up to 100 dwellings on the land 1.0 Introduction I refer to your request for the provision of traffic engineering advice in relation to the proposal to accommodate up to 100 dwellings on land at 62 Lake MacDonald Drive, Cooroy. I have previously provided preliminary advice regarding access options for potential development of the land in July 2023 recommending that any access should be onto Dianella Court (rather than directly onto Lake MacDonald Drive), at the location depicted on the concept plan at Appendix A, together with upgrade to the Dianella Court intersection with Lake MacDonald Drive as also shown on the concept plan at Appendix A. I have since been provided with the Civil Operational works plans prepared by Covey & Associates included at Appendix B, which incorporate the recommendations of concept plan at Appendix A. The advice provides a more detailed assessment of the traffic engineering impacts associated with the proposal. 2.0 Existing traffic conditions The site locality is shown on the aerial photo in Figure 1. Existing peak hour traffic flows at the Elm Street / Lake MacDonald Drive intersection are shown in Figure 2, which indicate peak hour traffic flows in Lake MacDonald Drive of approximately 300 vehicles per hour (vph) at Elm Street, which suggests that Lake MacDonald Drive carries existing daily traffic flows of about 3000 vehicles per day (vpd). The existing Elm St / Lake MacDonald Dr intersection has a configuration that includes dedicated turning lanes in Elm St as shown in the aerial photo at Figure 3, and there is no history of accidents at the intersection. A previous traffic count in Swift Drive, which would be used by some traffic generated by the proposed development for access to/from the areas of Noosa in the east, carried traffic flows of approximately 600vpd in 2007.

Section 3
Figure 3: Existing Elm St / Lake MacDonald Dr intersection
Lake MacDonald Drive has a sign posted speed limit of 60km/h. There is an existing pedestrian path
along the northern side of the road, that links to the existing pathway system at Elm Street.
The existing Lake MacDonald Drive / Dianella Ct / Wilgee Ct intersection has a basic configuration
without turn lanes in Lake MacDonald Drive. There have been two recorded accidents at the intersection
as follows:
(a) September 2017 – Multi vehicle accident requiring medical attention, involving a vehicle travelling
along Lake MacDonald Drive colliding with the rear of vehicle turning right into either Wilgee Ct or
Dianella Ct.
(b) March 2023 – Multi vehicle accident resulting in a minor injury, involving a vehicle travelling along
Lake MacDonald Dr overtaking a vehicle that was turning right into either Wilgee Ct or Dianella Ct.
Sight lines from Dianella Ct toward the west along Lake MacDonald Dr are restricted by the horizontal
alignment of the road to approximately 210m, and to the east are restricted by the vertical alignment of
24.s.70.1 Page - 3
Section 4
the road to approximately 360m. Both of those sight lines exceed the Austroads Safe Intersection Sight Distance (SISD) requirement of 151m for a 70km/h design speed. The Swift Rd / Lake MacDonald Dr intersection includes a short passing lane in Lake MacDonald Drive to enable north-eastbound traffic to pass to the left of vehicles turning right into Swift Rd, as shown on the aerial photo at Figure 4. Sight distances from Swift Rd toward the east along Lake MacDonald Drive are restricted by the vertical alignment of the road to approximately 155m, and toward the west by the horizontal alignment of the road to approximately 300m. Both of those sight lines satisfy the SISD requirement. There is no history of crashes recorded at the Swift Rd / Lake MacDonald Dr intersection. Figure 4: Existing Swift Dr / Lake MacDonald Dr intersection The Swift Rd / Cooroy Noosa Road intersection includes right turn lanes in Cooroy Noosa Road as shown in the aerial photo at Figure 5. Cooroy Noosa Road has a sign posted speed limit of 80km/h at the intersection. Sight distances toward the east from Swift Rd significantly exceed the Austroads SISD requirement of 214m for a 90km/h design speed. The sight line available to vehicles waiting to turn right into Swift Rd from the east is restricted to just over 220m by the horizontal alignment of Cooroy Noosa Rd west of the intersection, and for vehicles waiting to turn left from Swift Rd toward Cooroy Noosa Rd in the east, the available sight line is improved to approximately 260m due to the configuration of the road configuration. Thus, the available sight lines satisfy the SISD requirement. Review of the accident history at the Swift Rd / Cooroy Noosa Rd intersection indicates 3 similar accidents in 2001/02 all involving a through vehicle along Cooroy Noosa Road colliding with the rear of a vehicle waiting to turn right into Swift Rd. When those accidents occurred there were not any turn lanes in Cooroy Noosa Road intersection, with turn lanes that are now in place at the intersection being implemented between 2003 and 2006, presumably in response to the earlier crash history. 24.s.70.1 Page - 4
Section 5
Figure 5: Existing Swift Rd / Cooroy Noosa Rd intersection
Since the intersection was upgraded to its current form after 2003, the following accidents have been
recorded at the intersection:
(a) April 2007 – Multi-vehicle accident requiring hospitalisation, between a through vehicle on Cooroy
Noosa Rd and a vehicle turning right into Swift Rd.
(b) December 2010 – Single vehicle accident during rain, with the vehicle leaving the road and
colliding with an object.
(c) May 2012 – Multi-vehicle accident requiring medial treatment, being a head-on crash between
vehicles travelling in opposite directions along Cooroy Noosa Rd.
(d) May 2023 - Multi-vehicle accident requiring hospitalisation, being a head-on crash between
vehicles travelling in opposite directions along Cooroy Noosa Rd.

Section 6
3.0 Traffic generation of the proposed development
It is understood that the development could comprise up to 100 dwellings. With the site having an area
of approximately 2ha excluding the proposed access road (Road 1), it has been reasonably assumed
that if there are to be 100 dwellings that they could comprise a townhouse style product, rather than
detached dwellings on separate individual allotments.
In that context, it has been assumed that the dwellings of the development would generate peak hour
traffic flows at a rate of 0.6 vph per dwellings, noting that NSW RMS Guide to Traffic Generating
Developments recommends a medium density traffic generation rate of 0.5-0.65vph per dwelling for
townhouses having 3 or more bedrooms.
In terms of the distribution of that generated traffic to the network, the following reasonable assumptions
have been made:
(a) Peak hour traffic flows would have a 70/30 split during peak hour periods, with 70% of traffic
departing and 30% returning during the AM peak, and vice versa in the PM peak.
(b) 75% of site generated traffic would be oriented toward the west along Lake MacDonald Drive
(to/from the Elm St intersection) and 25% oriented toward the east (for travel to/from the areas of
Noosa further east).
(c) Of the traffic oriented toward the Elm St intersection, it is assumed that 25% would travel to/from
the north along Elm St, and 75% would travel to/from the south along Elm St.
The assignment of site generated traffic flows to the road network estimated on the above basis, is
shown in Figure 6.

Section 7
4.0 Impacts on the surrounding network 4.1 Dianella Ct / Lake MacDonald Dr intersection In relation to the vehicular access opportunities for the site, it would not be appropriate to attempt to achieve an independent site access onto Lake MacDonald Dr, because the combination of the existing vertical and horizontal alignment of Lake MacDonald Dr west of the Dianella Ct intersection at the site frontage is such that achievement of an isolated access location that achieves SISD requirements in a position sufficiently clear of the Dianella Ct intersection is not possible. The proposed upgrade to the Dianella Ct / Lake MacDonald Dr intersection and the access to the development site off Dianella Ct, as shown on the Covey civil engineering plans at Appendix B, is consistent with the arrangements shown in the concept plan at Appendix A and would operate in a safe and efficient manner, satisfactorily ameliorating the impacts of the proposed development, subject to the proposed raised central median in Lake MacDonald Dr east of the intersection as seen on the Covey plans, being replaced with a painted median as shown on the concept plan at Appendix A. This is to enable the small number of vehicles that currently turn right into Wilgee Ct from the east, to be able to move into that painted median zone so that following westbound vehicles can then move safely past the left-hand side of those vehicles turning right into Wilgee Ct. With there being only about 300vph moving along Lake MacDonald Drive east of Elm Street, the volumes of traffic using Dianella Ct and Wilgee Ct will not be sufficient to cause capacity concern, and the proposed CHR(S) right turn lane treatment introduced to Lake MacDonald Dr at the intersection as part of the intersection upgrade works, is all that is warranted by chart at Figure 3.25 of Austroads Guide to Traffic Management Part 6. 4.2 Elm St / Lake MacDonald Dr intersection To verify that the existing Elm St / Lake MacDonald Dr intersection has sufficient capacity to accommodate traffic generated by the proposed development, assessment been undertaken using the SIDRA software package, using default settings, under predicted year 2035 peak hour conditions with the proposed development fully operational. That assessment has assumed that the 2023 peak hour traffic flows indicated in Figure 2, would increase at a rate of 1%pa compound across the 12-year period to 2035, and that site generated traffic flows in Figure 6 would then be added. The resultant peak hour traffic flows are shown in Figure 7, and the intersection configuration used in the analysis is shown in Figure 8.

Section 10
4.3 Swift Dr / Lake MacDonald Dr intersection The small number of traffic movements introduced to the Swift Dr / Lake MacDonald Dr intersection would be easily accommodated by the existing intersection in a safe and efficient manner. 4.4 Swift Dr / Cooroy Noosa Rd intersection Importantly, as the Swift Dr / Cooroy Noosa Rd intersection, the proposed development would not add to the critical right turn movement from Swift Dr toward Cooroy Noosa Road in the west, which is a movement that is required to simultaneously give way to both directions of traffic moving along Cooroy Noosa Road. The proposed development will only add to the left turn movement from Swift Dr toward Cooroy Noosa Rd in the east, and to the right turn movement into Swift Dr from Cooroy Noosa Rd in the east, and each of those movements only need to give way to eastbound Cooroy Noosa Road traffic. Those minor additional movements will be able to occur in a safe and efficient manner. 5.0 Conclusion The proposed vehicular access arrangements for development of the site at 62 Lake MacDonald Dr as shown on the Covey civil engineering plans at Appendix B, achieve a safe and satisfactory access configuration, although it is recommended that the raised central median in Lake MacDonald Dr east of the intersection as shown on those civil engineer plans be replaced with a painted median as shown on the concept plan at Appendix A, so as to enable the small number of vehicles that currently turn right into Wilgee Ct from the east, to be able to move into that painted median zone so that following westbound vehicles can then move safely past the left hand side of those vehicles turning right into Wilgee Ct. The additional traffic introduced to the wider road network by the proposed development can be satisfactory accommodated in a safe and efficient manner.
