I think we've discussed this here before - I'm sure this will be f'd up somehow. The state has redesigned our busiest interchange a few times and still fails to get it right. But it'll be cool to see how this works out.
New form of traffic interchange comes to Del.
Have you ever heard of a diverging diamond interchange? If you haven't, you're not alone. Delaware 105.9's Jon Budler reports.
The unusual traffic pattern idea was implemented by the state of Missouri in 2009. Now, Delaware is breaking ground this week on the first DDI on Route 1 and 72, just North of the C&D Canal. DelDOT Secretary Jennifer Cohan.
The pattern is unusual because motorists drive on the opposite side of the road for a short time. Engineering of it won notoriety from Popular Magazines “Best Innovations of 2009”. Cohan says there is a possibility it could be implemented in Sussex and Kent Counties in the future.
Cohan explained the new traffic pattern during a meeting with members of the Rehoboth Beach-Dewey Beach Chamber of Commerce on Tuesday
And now that I've looked at some pictures I think this design would have fixed that problem I mentioned above. They just completed the last redesign last year so I'm not holding my breath this is revisited anytime soon.

There is one of these in a city near me! I had no idea they had a special name though. I'm not usually near it at busy times so I don't know how well it works then but when I have gone through it, it seems fairly easy to understand and better than the intersection was before.

We have a tiny little traffic circle in my neighborhood, about a block from my house. People don't seem to comprehend that when making left turns, YOU HAVE TO GO ALL THE WAY AROUND. You can't cut left before the circle, like you think you're sneaky. I have almost hit so many people because the overgrown bushes on the corner make it a blind turn. Maybe the people in my neighborhood are extra stupid.
There's a traffic circle 10 minutes from my house. I still screw it up sometimes. I assume everyone is taking the normal route and - because nobody uses turn signals anymore - I occasionally cut someone off who is taking the second exit. As a true American I refuse to accept the blame for my error(s).
There is one of these near my work. I fucking hate it. I feel like I sit at the lights way longer than I used to and you can't turn on red which really pisses me off.
They're usually pretty easy to drive through! There's one near me that u was kinda involved in. From above they look crazy but as long as they're done right they feel pretty intuitive on the ground.

We have one in our town, I drive it at least twice a day. It wasn't hard to get used to. And it's funny to watch people who have never seen one try to negotiate it. LOL
Sorta related: We're getting a Michigan Left near our house. Ugh.
First time driving in MI, I was like "WTF is going on here?" 8 years later and I still don't think I have it all figured out.
I've never heard of this, so I had to Google it; I'm looking at a diagram and while I can see what's happening, I'm fuzzy on how it's helpful? Might be one of those things where you had to be there

Why is that better than just having four entrances so everyone is entering from the right lane? For example if you're headed east and want to get on the highway going south you get on before the highway and if you're going north you pass over the highway and still enter from the right lane and the entrance ramps curves. Then no lights are needed! (Hope I explained that well).

This video shows what it's like (my city is putting in quite a few).

I just looked those up - WHY do they exist? Instead of a left, take a right then a U turn? No - that's what you do when you fuck up and make a wrong turn. don't make that shit compulsory!
We just got one in rural MN and no one can figure it out. It's terrible. I was in it yesterday and a car literally stopped, in the circle, to let other cars in. WTF Alexandria!

You're talking about a cloverleaf? The main thing is usually that they take up a shitton of space. And they create a weave on the highway which can be bad depending on the volumes. And if the local street has bikes or peds all those merges and diverges suck. (Not that a ddi is perfect)
They are working on one of these about 5 miles from my house. I hate it already because of the never ending construction on the thing. It is mucking up my commute.
It was. I knew there was another traffic engineering type here but I wasn't sure if it was you.
I'm more in roadway and dabble in traffic occasionally.
Full disclosure, not a professional engineer. Only a lowly designer
Oh well then I won't talk to you aNY more! I love our roadway people. My husband is in site civil, and the more other people design things, the less I have to. I hate design. I'm a pe, ptoe but functionally I'm more of a planner. Lots of studies and modeling.

It's such a shame we can no longer speak. I'm fascinated by planning and modeling.
