Shit that annoys you

[J. Barron DeJong]

Not sure we're on the same page? I'm talking about the person in the inside lane going through (exit at 12 o'clock) while the person in the outside lane stays in the roundabout, intending to exit at nine o'clock. So inside person exits across a lane of traffic that potentially is staying in the circle. I just looked for an opening and exited, but have no idea if that's the intent.

Yeah, I wasn’t talking about your situation, just thinking about skared’s diagram.

[J. Barron DeJong]

You could probably get away with it most of the time... but if someone is right next to you wanting to go straight through and you sideswipe them trying to turn right from the inside, they're gonna be pissed and you're gonna get a ticket.

Right. Wasn’t picturing that you and the car right next to you could enter side by side…

This is usually how it works:

usually is the key word here. consistency would be nice so I'm not guessing.

There is a new roundabout at our big hospital - the circle is maybe 15-20 feet wide and it has walls above eye level so you can't see through the circle. And despite it's size - it has two lanes going around it. One of the most comical designs ever.

But nobody blows into at 35mph, so maybe brilliant?

tiny roundabout

This is often the core issue. Roundabouts installed where traffic lights used to be, and there just isn't enough real estate to do it properly. Forcing the cars to turn right into a roundabout makes them slow down.

We have a new one that's no bigger than the small intersection it replaced, and the island part is flat so delivery trucks can get through. Well guess what... people are just driving straight through the middle, so now it's a 30 mph uncontrolled intersection with a barely perceptible speed bump. Yay "progress!"

There are a couple of roundabouts in neighborhoods near me in SF that have been in place at least 50 years. A couple years back, the city put up stop signs at all the entrances to said roundabouts. Because people are retards

That sounds like a fun thing to do in my spare time. I'll guess it's going to say is there many different types of roundabouts that can be built. Including a two lane roundabout that's about 15 feet wide with 5ish foot walls around the circle.

Those diagrams are all wrong. This is how you properly navigate a roundabout. Works from either lane.

What’s the problem with being on the inside lane and when making the right, since it’s the same path as for those heading straight or making a U-turn when coming from a different entrance?

(Other than the lane markings at the entrance…)

I assume it’s just to maintain higher throughput, not a concern about right of ways, or creating some hazard?

You’re thinking about it half way. Right lane is ONLY for right turn or straight. Left lane is ONLY to go straight, turn left, or make a u turn.

Being on the inside to turn right will be a problem for the right lane folk. Being on the outside to do a u turn will be a problem for the inside folk. When entering the roundabout you have to yield to inside folk who are exiting the roundabout immediately after where you’re entering.

If there’s more than two car lengths my car is gonna fill it. If that means somebody slows down substantially that means they aren’t matching speed in the roundabout and I’d be happy to discuss roundabout strategy with them over coffee.

WTF happened to merging at freeway speed???

While I don't have the answer to your question, I DO know that this ISN'T the way:

Not just in roundabouts but everywhere--yield doesn't mean enter, turn right on red, etc if the car with the right of way can slam on the brakes in time.
Curious where your matching speed rule comes from .

You got people enforcing those in your state? That must be nice.

He didn't match my skid into the 4 way stop, so I'm first.

Do you imagine that matching speed with traffic isn’t a basic traffic concept? Especially in high traffic density situations? That’s not a thing you do?

Let’s chat over coffee.

And no, nobody should actually be slamming on brakes. But if somebody is traveling significantly faster than traffic I’m not terribly concerned if they have to slow down after I’ve entered a roundabout if I’m at the same speed as the person in front of me when they approach.

Hey, man... I never said *that.*

Intersection design is based on sight distance for entering traffic. If you are going significantly above the design speed for the roadway, then the sight distance will be quite a bit more than the intersection was designed for and the speeding car has just made the intersection unsafe.

So, if you are entering a roundabout at +35mph, you are the unsafe driver, as everyone else is going 15-20mph and expecting you to do the same. Remember that is not really excess speed that is dangerous to other drivers... its unexpected differences in speed that is dangerous.

this is why properly designed roundabouts will always have a chicane/wiggle, or other traffic calming device before entering to ensure entering traffic has slowed way down from standard road speed.

The worst is when you get stuck behind someone on an on-ramp who not only doesn't try to accelerate to freeway speed, but basically just gets up to about 40 and keeps it there. It's infuriating.

40mph frequently is freeway speed.
Or feed, since a lot of people are eating ramen or cereal while on the freeway.

Fuck you man. My +20yr old 4runner takes a while to get up to speed at any kind of elevation, at any kind of incline. Respect your elder cars!

[riser4]

A good traffic circle should be designed so you can take it at 70MPH without going over the middle.

There are a couple of intersections in Truckee where people can turn right on red onto 267, a 55 MPH road. People are incapable of judging closing distance of cars going that speed. I've had a couple of near misses over the years.

One issue with roundabouts, esp winter weekends, is that cars get backed up and people won't let cars enter. Per the chief of police when you're stopped in a roundabout you have to keep the entering lane clear, just like you do at any other intersection. In practice this means zipper merging, which a lot of people refuse to do.
