​​​​​Flashing yellow caution lights to turning traffic

The problem

Many intersections throughout the metropolitan area operate as a parallel crossing, where pedestrians cross parallel with running traffic. These crossings are commonly used in Perth and around the world as a congestion management tool to maximise the number of vehicle movements through an intersection at one time.

Customer feedback tells us that too many times left turning drivers and crossing pedestrians are at odds with each other, with confusion over who has right of way. Not only does this become unsafe for pedestrians but it can cause major delays and congestion on Perth roads.

The solution

To remind motorists of the road rules, flashing yellow 'caution' lights were trialled in the Perth CBD and Northbridge. The trial aimed to reinforce the 'give way to pedestrian' law and improve driver behaviour.​

What does a flashing yellow light mean for drivers?

A flashing yellow 'caution' light reminds drivers the pedestrian has right of way. Even if a green light is displayed (not a green turning arrow), a flashing yellow light means the driver must allow pedestrians to cross before continuing the turn.

What does a flashing yellow light mean for pedestrians?

A flashing yellow 'caution' light changes nothing for pedestrians. Pedestrians should continue to observe the 'green man', 'flashing red man' and 'solid red man' signals at these intersections.

Watch the animation below to see how these lights operate.

Where
The five trial sites included:
  • William Street and St Georges Terrace - resulting in a 88 per cent reduction in (vehicle/pedestrian) conflicts at this location
  • William Street and James Street
  • William Street and Aberdeen Street
  • Hay Street and Victoria Avenue
  • Hay Street and Hill Street
What's next?

We are now looking to expand the trial to up to 12 additional locations to be announced soon. The installation of the further sites will be completed by June 2017.
