Spurred by a related thread, it is apparent that little thought (or even malevolent thought) has been applied to the phasing of these devices. There is no doubt these lights are linked, as the results are always the same.
I have a couple of favourites. Traffic turning right from Yamba Drive heading north into Hindmarsh heading east are always stopped immediately at the Palmer Street lights. These should be reset to stop traffic once Yamba traffic is given the green. ie, only stopping the far fewer vehicles turning left onto Hindmarsh east from Yamba heading south.
Another is the traffic given a green to turn right onto Athllon Drive fom Beasley Street (Mawson) are always stopped at the next intersection, Mawson Drive. These should be reset to turn red when any traffic from Beasley Street (Torrens) turning left onto Athllon is given the green. This traffic is allowed to turn left at any time.
Disproportionate timing is also comment worthy. Monaro Highway/Mugga Lane morning timing is approximately 2.5 minutes/20 seconds. Traffic heading south on the Monaro turning right into Mugga Lane can take 3 or 4 changes to get through. Yes, there is a shedload of traffic heading north on the Monaro, but another 10 or 15 seconds per cycle would certainly help the turners. Long Gully onto Yamba in the afternoon has similar timing, but giving huge green times to Yamba heading south, when there is little traffic.
I’m sure other RAers have their own examples.
Mr Gill, are you there?
