More than counting cars

We enlisted the help of the transport and traffic experts at Stantec (formerly GTA Consultants) to help us collect the facts and figures that underpin the Glen Iris Estate traffic management plan.
But their specialist insights weren’t limited to just counting cars or confirming peak traffic times.
They also looked for solutions to guarantee long-term design and function for Berrigan Drive and local roads, and ensure safety and ease of access for both new and existing Glen Iris residents.
Aspects such as road hierarchy and functionality were considered so that traffic could be directed to logical points in and out of the new estate.
The whole process involved a high level of detailed traffic modelling and analysis, carefully considering needs from all sides.
As a result, 95% of the new traffic generated by the Glen Iris Estate development will be contained on new roads. That means minimal additional traffic onto existing residential streets.
Key initiatives include:
New four-way traffic lights on Berrigan Drive
Enabling safer right turn exits and entries in and out of Glen Iris, the new traffic lights have been endorsed by Main Roads WA and are now progressing through the next stages of design and approvals.
Introducing a new controlled access point, the new intersection will significantly improve safety and reduce congestion for existing residents as they access Berrigan Drive, and surrounding arterial roads, including the Kwinana Freeway and Jandakot Road.
New connector road
The capacity modelling indicates the expected daily traffic flows for this main access road into the new estate will be well within the thresholds outlined for neighbourhood connector roads.
Turnbury Park Drive
Closure of the Turnbury Park Drive intersection on Berrigan Drive will provide the necessary separation distance for the new Berrigan Drive traffic signals, and in turn remove a known location of many car accidents and local traffic congestion in peak periods. This will improve safety and ease current congestion issues.
The Turnbury Park Drive / Lakes Boulevard intersection
Closure of the priority-controlled right-turn movements at the Turnbury Park Drive and The Lakes Boulevard intersection to help address current road safety issues.
Lakes Boulevard intersection
The Lakes Boulevard intersection on Berrigan Drive will be modified to become a left in, left out turning arrangement. Improved access to the new traffic lights on Berrigan Drive will provide much safer and convenient opportunities in and out of the area for residents on Lakes Boulevard and The Fairway.
Importantly, Lakes Boulevard will remain closed at the southern end near Imlah Court.
Carparking, pathways and cycleways
Carparking will typically be included in the verges of roads adjacent to shared spaces such as parks and shops, while group housing developments will need to provide resident and visitor parking ratios as prescribed by the City of Cockburn.
For those leaving the car at home, walking, jogging and cycling will be encouraged with a network of well-lit cycleways and pathways throughout the new Glen Iris Estate.
