[edit: for clarity, I am not against roundabouts]I don't have real expertise in civil engineering Traffic lights have a smaller physical footprint and require less construction activity.Traffic lights fit on a cost spectrum from two stop sighs, to four stop signs, to stop signs plus blinking lights, to non-trivial signaling.First make it work. Then make it good. Then make it fast.Engineering is not a one size fits all discipline.[edit: I have a background in urban planning, architecture, and real-estate development]
You forgot roundabouts with traffic lights.Here’s one in Australia near Perth:<a href="https://youtu.be/h8lhX9Q6Z5g?si=eloUWLcH8q3eJiZH" rel="nofollow">https://youtu.be/h8lhX9Q6Z5g?si=eloUWLcH8q3eJiZHAnd I’m certain I’ve driven through other roundabouts with traffic lights in other states.
In England we even have roundabouts of roundabouts <a href="https://en.wikipedia.org/wiki/Magic_Roundabout_(Swindon)" rel="nofollow">https://en.wikipedia.org/wiki/Magic_Roundabout_(Swindon)

Traffic lights have a smaller physical footprint and require less construction activity.
Traffic lights fit on a cost spectrum from two stop sighs, to four stop signs, to stop signs plus blinking lights, to non-trivial signaling.

And I’m certain I’ve driven through other roundabouts with traffic lights in other states.
