The report on the Wanneroo City Council March 31 meeting agenda, which councillors will consider in Two Rocks tonight, said installation would start in April and finish in June.
The City plans to install the signals at the intersection of Marmion Avenue, Peony Boulevard and Lagoon Drive, with $690,000 allocated to stage one of works in this year�s budget.
Highlighting that there would not be enough space for two trucks travelling in opposite directions on Marmion Avenue to turn right simultaneously, the report said staff asked Main Roads to change the signal phases so the intersection would not require reconstruction in stage one.
�Administration sought to gain approval from (Main Roads) for a traffic signal design which would avoid simultaneous right turns,� the report said.
�More traffic signal phases could provide safer right turns for larger vehicles, as well as providing a safer pedestrian crossing environment.
�A disadvantage of more phases is that red-light delay is increased, this resulting in more traffic congestion.�
However, the report said Main Roads informed staff that two-phase signals were common and so the project would proceed with them to avoid delays.
�The risk of traffic conflict under the two-phase traffic signal design is considered minimal, with reliance placed on drivers and pedestrians to take care and give way as appropriate,� it said.
�Stage one works are scheduled to commence during April 2015 and be completed, with traffic signals commissioned, late June.
�Western Power and Telstra were contacted in relation to the lowering of their respective underground services and associated provision of power and communication connections for the traffic signals.�
The report said stage two would be considered in the 2015-16 budget, and involve upgrading turning lanes and connecting paths from the intersection to bus stops on both sides of Marmion Avenue.
The council agreed to upgrade the intersection in mid-2014 following an 18-month campaign by the Two Rocks Yanchep Residents Association (TRYRA) for traffic signals.
At TRYRA�s March 23 meeting, president Peter Wimsett said he was pleased they would get the signals.
�Some school kids are now given the money to go to McDonald�s to have their breakfast, so they are crossing that road at the worst time,� he said.
