The Beauty of Roundabouts

The city I grew up in had no roundabouts back then. Today it does have some, some were even made and removed again since. People there hate roundabouts.

The city I live nearby now has so many roundabouts that I can drive for over an hour without seeing a traffic light. It always had those, people are used to using them.

Guess what works better and barely has any traffic issues at all.

1d agoHN ↗

As a bicyclist I hate them, at least the smaller ones. Because they slow me down, can't take them with 40 to 50 kph, need to slow down to 30. But that was the intent, yes?

However, crossings with traffic lights I can take at any speed I'm able to, when they are green for me, and I don't need to turn. Or if I can oversee them from afar, and they are empty, and I can give a shit about 'lights'.

Some roundabouts here have bike pass troughs on the side (obviously only works if there is no turn to that side) for speedy drivers like you.

Other than that it's obviously by design. There is no reason to speed at constant 50kph in a city. Nether for a car, motorbike or e-bike.

The think I don’t like about not being able to “speed” at 50kph(!) through a city is that, at least in Australia with it’s excessive compliment of bureaucratic Karens, is the 30 > 50 > 70 > 60 > 40 > 30 > SCHOOL ZONE > 80 > 40 > 50 > 30 nightmare.

Which does two things, raises state revenue and causes drivers to spend way to much time concentrating on how fast they are going rather than driving to suit the conditions and paying focusing to what’s going on in front of them.

And don’t get me started on the pot holes.

[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]

The footprint is a cost problem once. They don't need power, computers, or technicians to come out and maintain the equipment constantly.

I like roundabouts over lights at small intersections. I still prefer simple give way/stop that changes the next intersection over roundabouts.

Lights suck unless there’s sufficient traffic.

This dreaming about roundabouts is as American as the fantasies about using metric one day.

9m agoHN ↗

They’re being used often in new construction areas. It’s just not likely that they’ll be retrofitted to existing areas due to needing more space than regular intersections.
