I used to commute an hour to work every day, each way, and the worst part was cross-merging traffic, exactly like there are 4 of in this design.
This would gridlock so fast. Actually I think it would gridlock so incredibly hard that cars would end up abandoned after they ran out of gas from how long they were stuck.
I assume the ‘engineer’ has never seen a road or drove a car, because even if we assume more infrastructure will solve induced demand, and even if everyone’s going at a nice 30mph, this intersection is gonna go at like 3 accidents/minute.
Those 180° turns look way too tight for semi-trailer trucks. Even the vans are drifting there.
And all those single lanes, merging, and tight turns are a recipe for congestion.
A proper roundabout would work much better, waste less concrete, and probably take up less space.
Not even 10am yet and enough of car brain for the day 🤦♂️.
And yes I get it, some countries consider roundabouts (the ones used almost everywhere in the world) some black magic.
This was obviously designed with the assumption that people know how to drive without getting in one another’s way.
This looks like hell…
It’s only one lane of traffic either way and you’ve got to merge in and out of two separate traffic flows in a short distance just to go ‘straight’ through to the other side.
That’s just a big roundabout
This is just a flattened highway interchange.
Also, holy shit so many combination enter/exit lanes, so many potential points of high-velocity conflict!
Exacrly my thought, those already exist and work wonderfully, why try to make them flat and 100 times more dangerous in the process?
Well this is a very roundabout way of getting places
What do these folks have against roundabouts?
This is a roundabout. It’s just three roundabouts that only connect two roads each.
It’s wonderful yes but relies on people leaving space to allow zippering.
Unfortunately everyone is a bastard and goes bumper to bumper.
Around my area we have combination highway on ramps and exits where the lane for getting on immediately becomes the next exit. They are incredibly stressful and dangerous given just a tiny bit of traffic, everybody is frantically trying to merge on and off a short strip and accidents happen all the time. This intersection turns the entire road into that design lmao, they’re off their ass if they really think this design is any good
I know right, it’s basically just a roundabout with added dangers.
Yeah that was my first thought too. They have those where I live, they’re usually like a quarter mile long but all of the action usually goes down in the first 100 feet or so, mega conflict zone.
@destructdisc LOL, this is like a very fucked up roundabout. It takes way more space and is way more dangerous.
dude bro, we need to drive at 90 MILES PER HOUR AT ALL TIMES!
As if normal roundabouts didn’t already take up enough space.
This design is an abomination really, there’d be so many accidents around the merging, where the traffic streams effectively have to swap over.
Because, you know, cars and car infrastructure don’t already take up massive amounts of space as is.
The only defence of this is that it would take LESS space than some kind of cloverleaf system. I think this whole design is trying to be space efficient whilst attemptign to keep traffic flowing (which it wouldn’t do).
Making it so most of the traffic is in a merging state is a really bad idea. So many accidents happen because of people changing lanes, and here a large part of the traffic needs to do that, plus has little space and time to do it in. I’d love to see this made in something like City Skylines, just to show how bad it gets (without the car accidents, though, unless newest versions also simulate that).
and here a large part of the traffic needs to [change lanes]
Only if you make a right turn you dont have to merge, but then there is still a lane merging into yours. So a (very) large part of the traffic has to change lanes, but everybody is merging. If you want to drive straight, you have to merge twice. Total madness.
