    Traffic signal innovation benefits all

    • WA leads the way with LED traffic signal operation
    • Drivers, pedestrians and the environment benefit 

    In an Australian first, Western Australia is now the first State to have all traffic signals operating with LED displays due to the recent completion of a six-year program converting all lights to LED. 

     

    Transport Minister Dean Nalder said Main Roads WA was leading the nation with the implementation of a number of innovative and sustainable initiatives being applied at signalised intersections throughout the State.

     

    "The conversion to the more efficient and cost-effective LED displays on all traffic signals will deliver ongoing substantial savings, with an estimated 75 per cent reduction in power consumption," Mr Nalder said.

     

    Other key initiatives to improve traffic signal operations already successfully introduced under the Traffic Congestion Management Program include: 

    • 12 extra pedestrian countdown timers installed
    • flashing yellow caution lights for a turning-traffic trial at five locations
    • right-turn filtering trial at six sites on Canning Highway
    • improved traffic signal timings at 93 intersections along nine key traffic routes across the Perth metropolitan area. 

    The Minister said he was pleased with the early results from the initiatives that were part of a planned strategic approach to deliver immediate benefits and improved safety at key congestion hotspots.

     

    "This is really just the start.  We are moving into new territory with our traffic signals and looking at ways we can improve our operations. This year, our traffic signal timing improvement project will expand to include 201 traffic signals over 20 routes," he said.

     

    Fact File

    • The new LED traffic signal lanterns replaced the previous technology - 20 watt Extra Low Voltage krypton traffic signal lanterns
    • An LED display uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors in store signs and billboards, and in recent years they have also become commonly used in destination signs on public transport vehicles.  LED displays are capable of providing general illumination in addition to visual display purposes
    • Main Roads WA currently manages just under 1,000 sets of traffic signals throughout WA from Karratha to Busselton to Kalgoorlie-Boulder

    • The State Government is spending $1.6 billion on roads and public transport in 2015-16
