Title: DDI-roundabout hybrid?
Post by: tradephoric on May 11, 2015, 12:33:43 PM
Proposed DDI-roundabout hybrid interchange at I-49 and 155th Street in Missouri.  They dun lost their damn mind!

Not only do I see nothing wrong with it, I kinda like it.  If you're in the roundabout, the only thing you're concerned about is where to exit, which would be signed. Otherwise, it's pretty straight forward. 

Tradephoric: Since you have a huge beef about DDIs having 2 traffic signals, this type design eliminates one of them and keeps traffic moving.  You of all people should actually like the design!

I designed something very much like that but with more lanes in one of the Redesigning threads a few months ago.

Looks fine to me. At motorist level, I don't see what would be confusing - just follow the signs.

But, then again, maybe it will destroy the wonderful signal progression on 155th Street.

I remember that very clearly. Here's my drawing:

I represent the vast majority of motorists who don't like getting stopped at red lights.  Apparently, based on your snarky remark, you don't care if people get stopped and experience delays at red lights.   You are making a bad situation worse if you promote interchange designs that kill signal progression.

I was responding to someone's snarky remarks.  I wasn't the one who brought up signal progression in this thread.

Your reputation precedes you (also you answered the same guy twice.)

What the hell else could you possibly mean by your original post? Does the new interchange have a negative impact on the Canada goose? Does it interfere with the long pig harvest? Others have already said they've designed something similar.  You hate DDIs, we all know that. Congrats for getting your name out there.

I'll answer you twice too, just for the hell of it.  I'll be overzealous with traffic signal progression to make up for the disinterest that many people seem to have on the subject (again though, i wasn't the one to initially bring it up in this thread).  I don't hate DDI's I just believe they are being overbuilt.  In a previous thread, I posted an example of a DDI that i believe works quite well...

I'm not totally opposed to DDIs.  Here is a scenario where a DDI works well...

I can't help but think that this could be even better is a similar roundabout were used on the left side of the bridge as well instead of the signal.  The DDI would a completely free-flow interchange.

I usually don't mind them. Gives me a chance to stop pedaling and have a bit of water.

This design could be effective at cutting the number of roundabouts down when you are dealing with frontage roads.  Two roundabouts are better than four.

Why not just make one larger roundabout on each side and connect everything to it?

How about one humongous roundabout?

Because it's Missouri and the whole point is to not have to build any new bridge capacity.

Are you going to retract your claim that i hate DDIs?  In a previous thread i posted an example of a DDI that i think works well.  I'm going to get defensive if you make an unsubstantiated claim.  If you want to focus on the subject, then we can have a civil conversation.  If you want to throw mud, I'm going to throw mud back until you're covered in it.

ROW in most of Missouri is pretty cheap once you get away from the urban centers of KC, STL, Columbia, and Springfield. Most of the ROW in the suburbs, like this is, were acquired back in the 60s and 70s. The main problems in MO for building roads are money and (to a lesser extent) NIMBYs.
