Australia is a land of motonormativity. It's bizarre to state that the same laws apply as they clearly don't e.g. drivers don't get pulled over and...

How would this accommodate the visual systems of cyclists as I learned from posters here they're not able to perceive red light?
Was also wondering if someone has modelled a computer vision system on that of bees - and perhaps the 4th light would be a non-human- visible UV one (or more realistically IR) for benefit of the robots? That could then be pulsed / polarised to send more information without distracting humans?
No more colours. There should be more states instead:
Flashing amber - Minimal traffic - All road users proceed with caution.
Steady red, amber, green - Expected traffic volumes - Obey signals.
Pulsing red, amber, green - Congestion exists. Return motor vehicle to parking/garage, proceed using active travel methods only.
I might have missed it, but what about "established red"?
I don't think we need more states - we need more phases / "smarter" lights.
And "leading pedestrian signals". (And possibly "early cycle release" although IMHO this is another sign of 2nd or 3rd class infra *).
That may collide with our existing road traffic rules though, like if there's a green light for you then you can normally proceed in any direction. Perhaps this can change though? I'm thinking about the latest Highway Code guidance tweaks around traffic turning into a side road letting crossing pedestrians / cyclists going straight on do so.
* Early cycle release - there are a few now here in Edinburgh. The UK seems to use these where in NL they'd likely have completely separated bike paths - with their own lights if even needed. These seem to appear where we have Advanced Stop Lines / bike boxes - and I don't see lots of ASLs in NL...
More colours? But we only need green! These traffic lights are woke!
Would this be a computer model designed by the same sort of people who brought us those revolutionary and super safe driverless car thingies by any chance ?
