    Kwinana Freeway merging trial aims to improve traffic flow

    Sunday, 20 April 2014
    • Modified design of merging points to be trialled at three Kwinana Freeway on-ramps
    • Trial this month to improve traffic flow in known hot spots

    Motorists on the Kwinana Freeway will take part in a merging trial in a move designed to improve traffic flow during peak hour.


    The trial by Main Roads Western Australia will see the application of a new line marking design to the existing merging points at the northbound on-ramps at Russell Road, Beeliar Drive and Berrigan Drive.


    Transport Minister Dean Nalder said the trial formed part of the Traffic Congestion Management Program to help improve the flow of traffic on the freeway.


    “We understand that poor merging is one of the big frustrations for Perth motorists. This trial is just one initiative as we investigate ways to help keep Perth moving,” Mr Nalder said.


    The modified designs will see a broken or dotted line introduced into the merging lane of the northbound on-ramps from Berrigan Drive to Russell Road.  These dotted lines indicate to drivers in the merging lane that they must give way to nearby traffic regardless of which vehicle is in front.


    Motorists are encouraged to give feedback on the new Keep Perth Moving webpages on the Main Roads website.


    “Busy traffic is an unfortunate reality of living in a growing, vibrant city.  There is no easy solution however educating road users on how their own behaviour can affect traffic flow is a major focus of the program.  I encourage all road users to get involved and learn more about what the State Government is doing to improve traffic flow,” the Minister said.


    The trial is based on a design used in Victoria by VicRoads and has been modified to suit conditions on the Kwinana Freeway.


    A full evaluation will be undertaken, including a before and after comparison.  Detailed analysis will compare the effectiveness of the three differently applied line marking options. If successful, the line marking will be considered for implementation throughout the wider road network.
