In South Australia the central traffic control computer cancels the lights request if the vehicle leaves the sensor before the phase is initiated. Other states may of course have inferior systems.

There are suburban areas in Brisbane and Qld that have signs at light controlled intersections where there is a formed separate left lane "left turn anytime with care" and also there are signs on control lights at intersections "U Turns Permitted" they are the only places where legal "U" turns can be made,all others will get you an infringement notice if caught.

Just a quick bit of research suggests the system used across Australia and a number of other major centres/cities across the world is a development of Sydney Coordinated Adaptive Traffic System (SCATS), which was originally put in place by NSW (what is now RMS) in 1972 and adopted by SA in 1982.
From memory at low traffic times it goes to a timed phasing to give secondary roads a go, otherwise you could be a lone car sitting at an intersection for a very long time.
Of course you realise traffic lights are always on red more than green.
I do remember learning about this when I was at uni in the mid 70s

Isn't SCAT the word they use in Africa to describe what bush animals leave behind them?
If so that certainly describes the system WA uses to hold up traffic....no rhyme nor reason for the long delays at most lights except so called "safety".....a stopped car is less likely to be involved in an accident!
As for even considering letting the average local use his own judgement!!!! Don't be daft, we see the results of that in the road fatality figures.

And the example is SCATS and it's an acronym, not a word.

The intersection nearest me has a 'left turn permitted after stopping' sign, and I can tell you if cars go through turning left it won't trigger the lights. I know this as my bike won't trigger the lights if I'm going straight ahead and wish the left turning people would set off the lights. I've even had to jump off and run across to push the walk button.
About 90% of the cars don't stop, just roll through, just like stop signs. I feel like I'm the only one that comes to a complete stop.
As for WA drivers being shocking, discotwinturbo, I spent two weeks in October/November this year and have been there quite a bit and find them much better than Sydney or Melbourne drivers. Maybe they just give me a wide berth due to my interstate plates. My brother who has lived there since the mid 70s warned me about 'heavy traffic'. We laughed at Perth's 'heavy traffic'.
