  What would you expect them to do? Go straight from red to green?

  • possiblylinux127@lemmy.zip ⁨11⁩ ⁨months⁩ ago

    That’s what normally happens

    Yes. That’s what happens in most countries

    • andthenthreemore@startrek.website ⁨11⁩ ⁨months⁩ ago

      So they just go straight to green without any warning?

      • geophysicist@discuss.tchncs.de ⁨11⁩ ⁨months⁩ ago

        Why would you need a warning? It’s not a race. In fact, that’s probably part of the reasoning of not having a yellow before changing to green

        More or less. If you’re paying attention to what’s going on around you you’ll notice other traffic stop before your light turns green. There’s also typically a second or two where all lights are red before one turns green to make sure the intersection is clear.

    That’s what traffic lights do here in Spain. I don’t actually know if Red-yellow-green has any advantage

      That’s the part where you spin your tires to burn

    Purple.

  This is normal in Europe too, and actually helps to clear up the traffic. You see red+yellow lights on, you put on first gear and prepare to start moving.

    in many (maybe even 'most') american towns and cities, there would be too many drivers going on that yellow and not waiting for the green.

    • hemko@lemmy.dbzer0.com ⁨11⁩ ⁨months⁩ ago

      There’s a clear difference though. Yellow = no-go, yellow+red = prepare to go

      They’d be running a red light

  In the UK, they go Green-Yellow-Red-Yellow-Green, which seems pretty sensible to me.

    Imagine green-blinking green-yellow-red-red+yellow-green.

  Czechs do this too. Gives you time to menacingly dev your engine at the car next to you.

  I’ve seen that in some German places as well

  source

  • zout@kbin.social ⁨11⁩ ⁨months⁩ ago

    All German places I've seen, this seems to be a national thing.

      @zout No. Green, Yellow, Red, Red+Yellow, Green...
      There. Are. Four. Phases.
      After Yellow always comes Red. (At least in Germany)

        Never noticed this, will look out for this next time I cross the border.

  In some biggest country traffic lights FSM looks like this: red->red+yellow->green->blinking green->yellow->red, and can transition to blinking yellow from any state.
