Flashing yellow caution lights to turning traffic
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 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.
Flashing yellow 'caution' lights are being rolled out on the wider network 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 is aimed at turning drivers as a reminder that pedestrians have 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 person', 'flashing red person' and 'solid red person' signals at these intersections.
Watch the animation below to see how these lights operate.
The following sites were fitted flashing yellow 'caution' lights in 2017:
- Canning Highway and Riseley Street
- Stirling Highway and Loch Street
- Stirling Highway and Dalkeith Road
- Stirling Highway and Napoleon Street
- Stirling Highway and Jarrad Street
- West Coast Highway and Brighton Road
- Guildford Road and King William Street
- Canning Highway and Reynolds Road
- Canning Highway and Henley Street
- Canning Highway and Sleat Road
- Canning Highway and South Terrace
- Albany Highway and Olga Road
To help remind motorists of their road rules, we researched a successful traffic signal treatment seen in Barcelona, Spain, and trialled it in the Perth CBD and Northbridge.
The trial showed that the caution lights were successful in alerting drivers to watch out for pedestrians, with one trial site resulting in a 88 per cent reduction in vehicle/pedestrian conflicts.
The five trial sites included:
- William Street and St Georges Terrace
- William Street and James Street
- William Street and Aberdeen Street
- Hay Street and Victoria Avenue
- Hay Street and Hill Street
