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 ?
