Right turn filtering
It's a familiar story - you are held up at a green light and want to turn right but a red arrow prevents you from doing so - even when there are no cars around. Not only does this increase driver frustration but it can be highly inefficient for our network.
We have tried and tested a solution to reduce your wait time during non-peak times. At suitable locations, we will turn off the red right-turn arrow between the hours of 9pm and 6am to allow drivers to turn right on a green through signal, when it is safe to do so.
During 2017, we installed this type of treatment at eight intersections:
- South Street and McCombe Avenue
- Orrong Road and Pilbara Street
- Orrong Road and Kewdale Road
- Orrong Road and McDowell Street
- Karrinyup Road and Jones Street
- Karrinyup Road and Main Street
- Morley Drive and Wellington Road
- Guildford Road / West Road / Lord Street

In 2016, we investigated the effect of turning off the red right-turn arrow during non-peak times when traffic volumes were low on Canning Highway.
Between the hours of 9pm and 6am, the red right-turn arrow was not displayed and drivers were able to turn right on a green through signal, when there was a safe gap in oncoming vehicles. The trial minimised wait time for road users, with a 44 per cent reduction in delays observed across the six sites.
The trial locations included:
- Canning Highway and Henley Street
- Canning Highway and Reynolds Road
- Canning Highway and Ardross Street
- Canning Highway and Riseley Street
- Canning Highway and Stock Road
- Canning Highway and Queen Victoria Street
