Seattle Department of Transportation and Washington State DOT have honestly gotten way too creative. It's like every city, every locale, and sometimes every street has a new collection of obstacles and rules to circumnavigate.

Roundabouts are great, but they should probably be round. In this case, it seems that it'd be easy to navigate if the two roads were brought into a single, simple roundabout intersection like you see at any other location.

Apparently I'm sticking my neck out here, but it really doesn't seem that hard. Overhead, I can intuit the path I would take, and if I imagine it first-person, it seems even more obvious.

It's frustrating riding with certain other American drivers in other countries. I've met numerous folks now that seem upset that they have to actually pay attention to their driving and the traffic. Meanwhile I'm horrified that they're apparently just ... completely on auto-pilot in the US.

It is intentional. The idea is to force drivers to reduce speed, and the mechanism is because it isn't familiar to the drivers. The claim is it forces them to be thoughtful.

Whether or not it works or is a good idea is not something on which I'm opining.

Keep in mind that a lot of these traffic devices look way more confusing from above than they actually look while on the ground. From above you can see the whole device at once, and trying to trace a path through it can feel overwhelming, but when you're actually going through it your view is usually restricted in ways that limit your perceived choices at any point in time.

The article explains why they made the decision not to do a traditional dog-bone interchange with two circular roundabouts. Namely, there were right of way limitations and a need to incorporate heavy farm trucks making a left turn. So, they ended up with basically 1.5 roundabouts which represents a simplification over the dog bone.

I'd say just the opposite. Indeed, in the UK it's normal for the signs leading up to a roundabout to include an overhead map view, since that's often the easiest way to understand what you need to do to get where you want to.

No, you're definitely not the only one who likes them. Some folks complain about them when they first go in, but they tend to figure it out.

WSDOT has been encouraging them for a few years now, and my town has several new roundabouts as a result -- and lots of other cities across the state are using them. They've made navigating those intersections way easier, reduced traffic "waiting times", and generally improved safety versus a lighted intersection. I'm glad they're continuing to find ways to make them work.

It seemed when I was growing up in NJ, the state DOT was taking out the giant roundabouts that they were famous for, and now in Washington, they're having a huge resurgence.

US here. There seems to be an obsession at the moment with adding roundabouts in my area. They don’t always fit where they are put. Some of them have a stop sign in the roundabout?

When asked why, the answer is reducing “points of conflict”, which is a static variable. There aren’t actually studies being done before or after to see if makes the flow of traffic better.

They are also adding them in walkable areas with the express intent of “traffic never stopping” which doesn’t go well with pedestrians crossing the street.

I think we can find better ways to spend money… including the salaries of the people dreaming up bizarre applications for these things.

I'll take a traditional cross with traffic signals or stop signs on all sides, it's simple and effective.

Roundabouts are a waste of space, disrupt traffic, and take more brain processing than I care to afford if I can help it. This particular example isn't even round.
