It's a diverging diamond interchange
Depends on where you live, America is an enormous country.
Obviously I'm an American and I've never once seen or heard of one of those, and I'm bewildered as to how the fuck they work, and if they do why the fuck choose them over something simpler
Also, it's one of the best interchanges you can have technically. There's no weaving and the cost to build is quite cheap as it is at most 2-levels and all ramps are the same-level so there's no need to cross a ramp over one side.
not even once
There's only like half a dozen of them in the whole of America.
How do you think it works? It should be pretty obvious I would think.
The side you're driving on switches to facilitate having both the exit and on ramps on the same level. That's all there is to it, there's no other purpose to it.
i want to build one of these in cities skylines now
How do you think it works?
I was thinking the same thing.
Do these things use red lights or is it literally just go whenever?
A crackhead broke a bridge in Georgia. I'd say yes.
Yeah its because your country is huge. How about you give some i it to the mexicans? How about all of you rural dumbfucks move to cities?
clover interchange is best interchange
They're for low to moderate traffic flows and the bottleneck occurs due to requiring lights at the direction switchovers.
It's not an amazing interchange but in terms of cost to traffic flow it's quite good.
There's already tons of diverging diamonds in the workshop.
If you're looking for a high-flow, unlighted, no lane change, no weaving, no ramp crossover interchange than a cyclone/turbine interchange is what you'd want.
City ((planners))) should be shot
This is pretty true now were adding roundabouts though so we'll see how that goes.
Yeah man, but it's all the government's fault. See, America has too much government. If you want bridges and infrastructure and cheap healthcare, you gotta get rid of the government and let the free market step in and there'll be roads everywhere, bridges across everything, and everyone will live to 100.
Your government controls too much man, gotta get rid of it, gotta pay less taxes. Especially the rich. If you keep making rich people pay taxes you're never going to have infrastructure.
Also, Jews, stop taxing the rich Jews at all. Like Zuckerberg, they're even more productive at creating jobs than white billionaires and every time you try and make them pay for bridges, somebody is going to go without a job. Actually you're lucky to have Facebook at all, look at my country -- we let the government build all our bridges and pay taxes for them to do so and now all the rich Jews have gone somewhere else (your country) and are busy creating jobs for you and running your government
construction costs intensify
clovers have the worst efficiency actually. They can at best handle moderate traffic loads and cost more than nearly every other interchange in existence. If land cost is high clover interchanges are absurdly expensive.
You can pick basically any single other interchange imaginable and it will outperform clovers.
Coming from rural PA, its a fucking mess. Older highways/freeways were last worked on in 2003. Needs to be changed for the good!
it's because they drive on the right side instead of the left
Europe has diverging diamonds as well, the directions are just reversed. They gain the same advantages as having the driving sides flip in the middle (cuts out ramp crossover)
Here's an easy way to put it. Concrete structures can last thousands of years. See, surviving Roman architecture.
Our infrastructure (highways, buildings and bridges, etc.) is made up of steel reinforced concrete architecture. It's smaller, cheaper, taller and more flexible in possible designs. The problem is, the steel turns into powder in only 50 years therefore we have to replace it every 50 years or the structures will collapse.
Yes there is alternative tech that will last much much longer than 50 years like composite-reinforced concrete architecture, but old habits die hard and we build all of this shit 50-100 years ago when steel was hot shit to build with.
tl;dr we need to replace it before it crumbles because steel.
I wonder how many deaths this has caused.
there is one in Atlanta and they'er just as shitty in heavy traffic as the the common intersections
Have a real interchange.
no, this is
That's not that bad
How do you get back on the freeway to continue the direction you were going? Dont these fuckers know about cloverleaf exchanges?
Basically city planners wont get their name known unles they are smart enough to invent a new interchange locally. So now that all good ideas are used they make ones to get attention and depend on foreveracarvigrins to defend their astetic bonuses online
Was it really that hard?
And despite all of that you still managed to put 4 traffic lights in there.
you are but like a baby
yes, it's retarded
nothing is standardized because of (((muh private sector))), even though most of america is just monotonous strip mall wasteland and tract housing developments
I don't know which Texas city has the worst highway system. Austin or Dallas-Fort Worth. Meanwhile Houston only has 2 rings that run around the city and makes it work.
What is the fucking point of an interchange if there are traffic lights on both sides? Is the continuous flow of traffic not the whole point of an interchange?
A third is being built actually, the Grand Parkway.
Those traffic lights are for the feeder roads, not the highway.
Feeder roads are standard in Texas.
cloverleafs can't handle much traffic
yeilding from the offramp but having stoplights going under.
Is there a sitch where this goes down well?
If the guy who has the benefit of yielding goes left they still have a chance to hit the light. Going right could be designed to yield with a light at the off-ramp. My best guess is a heavy traffic load comes off the ramp here, so they increased the capacity through this design.
Nope. It isn't the best, but it's near the top and better than most first world countries.
You in research for uni or private?
Where's my Hawaii flag
Congrats, you made it worse.
It removes 2 crossing points. I use these daily and they're fine.
Something that could have been solved by roundabouts.
im near a panic attack just looking at these monstrosities. how do thousands of people per year not die? American tourists that come here are shit drivers and this is insane.
That smoggy LA sprawl
If you know how to read a sign (or operate a smartphone to guild you step by step) and drive at a decent speed, it really isn't that difficult.
He plays a video game so he talks like a civil engineer.
It's just a stack interchange, brah.
Yeah I don't actually research traffic engineering, it's just a hobby cause of video games lol
I did my degree in mech eng but I've never done infrastructure stuff.
Compared to Europe? It's shite, (((OP))). Even the eastern EU slavic cucks have better motorways than you guys
oklahoma is planning one to be built by 2021
Should have never let those island niggers become a state
parts of the midwest all the way to the west coast have shit infrastructure failed dams bridges roads are fucking littered with pot holes why are we paying for this shit if no one is going to fix it
they all work, they look ugly.
but as long as both ways on the motorway have entrance and exit points that head down either directions on the cross road it all works.
ah. carry on. skylines is some of the degeneracy I can get behind.
it will work. but i cant see drivers getting mighty confused when they end up on the opposite side of normal flowing traffic. why could they just keep the lines going straight. instead of twisting them? doesnt make much sense.
Cities Skylines fag
why could they just keep the lines going straight. instead of twisting them? doesnt make much sense
So you can exit to the left without an overpass.
I...just...what the fuck?
The confusion does occur the first time you use one, a mild "wtf?" You need to be a complete retard to fuck up using one though.
I understand why it was build this way, but it would work only with relatively slow and low traffic, otherwise it would jam like there's no tomorrow.
What if one of the main ground lines was a little dug in and the other slightly elevated?
Wouldn't it keep the original design while getting rid of the traffic lights altogether?
inb4 traffic lights are cheaper
simcity tier design
Slow yes, usually 25 to 35 mph. They fucking work though, exiting the freeway and passing under/over the freeway on all green is great.
Seriously why don't Americans use roundabouts? You would only need two on either junction for the interchange for this to be 10x simpler. What a fucking nightmare.
So what the fuck is wrong with Cloverleaf interchanges? Why does everybody need to over complicate shit?
a fucking cloverleaf
1 - roundabouts would not work in this case
2 - they are being built everywhere that isn't a backwards coastal city shithole
...but we do
roundabouts would not work in this case
It's not about how fast you cross them, it's about how fast and how much cars can get to that intersection. Add to that picture at least 50-100 more cars on each side and you already will have a light jam. Anything more and it will be hell.
it's not about speed at all
the double crossover diamond completely eliminates two entire timing phases, allowing far more green time per cycle for every movement
8 individual approaches plus likely very high volumes compared to your pic
Come drive in California if you want to see horrible roads
part2 now with more hidden roads.
They go too slow and if you're behind a semi truck they have to go at like 1/3rd the speed otherwise they'll tip over.
Cloverleafs are just shitty
we should just drive everybody into a hyperbolic funnel and have them drive on the walls in circles until they reach an acceptable exit point
I'm a genius. This one is free.
This one is pretty cool.
I guess that's just a roundabout, except with multiple levels.
Americans will defend this
Ever been to LA OP? It's nothing but potholes and shitskin assholes
Is that florida? Looks like a hellscape I'm familiar with.
simcity 2000 - the movie
The non-main roads in some areas could do with a facelift, there's this one particular four way intersection where, if you're coming from the South you can't see the pedestrians crossing the sidewalk on the right side because there's a rampart blocking the view. Been like that for ten years and there's been at least 13 people that got hit because of that, yet the city hasn't seen fit to put up some kind of "Watch For Pedestrians" sign up.
Suburbia was a mistake.
shit like this is why I'm extremely uncomfortable with driving on routes I'm not somewhat familiar with I'd totally fuck this up at 2am if the road were all to myself and I'd end up colliding with and killing a family of five
No really, but its centred around motor vehicles and because of your "commie" obsession public transport its shit. You waste a lot of space and money.
what are earthquakes
If you ever wondered why so little original roman architecture actually remains standing, now you know why.
At least you can see the mountains, this was taken on a (((good))) day.
The worst infrastructure I've seen is in shitty neighborhoods and cities.
I like this kind much more, to be honest.
East of Oklahoma City.
Cloverleafs are great. The haters are faggots with no sense of aesthetics.
now... where did i park
How do people not die here?
i dont give a shit about them when im stuck in traffic due to a shitty design, or getting killed by some idiot due to the weaving at the on and off ramps
That would happen on any intersection.
it's fucking beautiful
The trouble is not that the infrastructure is bad per se. but the country is entirely too car-centric, and suburbs without adeqite trains or public transportation means that everyone drives to and from work every day, creating a congestion nightmare.
A few months ago I visited Miami, FL, which had some of the most wonderfully engineered and designed highway-systems I've ever seen. However, it was continually gridlocked. Miami is a city of millions with just one single train line which doesn't even go into most population centres. It's ridiculous.
America was developed around the car as transportation, and this has been its undoing in recent decades. The best highways in the world can't meet demand for what is a rather inefficient mode of transportation.
onramp right before an offramp is normal and ok because pretty
every intersection has traffic regardless of the design not because of the amount of vehicles on it
youre a fucking retard
92 somewhere in Duluth, isn't it? Fuck me that overpass is trash. Have to do it every time I'm going to Athens.
But user, thousands of people do die yearly. In 2015 - 35,092 fatalities.
almost as bad as this
We have light rail in my city but they are fucking empty all the time. They fucked up the streets wasted a bunch of money and space to make the light rail and it barely gets used, should've just stuck with buses, way more efficient.
I live in Miami. I commute around every day. Curious to which highways you saw
bruh, a bridge fucking collapsed here not too long ago. i35w. and were one of the wealthier states.
I don't think so. I have driven across the southern US ~10 times. There is always roadwork, but on average everything looks good. Places that were rough were getting attention the next time through.
The shit infrastructure must be up North in Yankee territory. No wonder, with tax and spend Dems in charge, like that Dam in Ca. They spend money on social services then act all surprised when physical things break.
American intersections cost hundreds of milions of dollars because they are uncapable of understanding how a simple roundabout works.
why would you say that is bad? It is a diamond intersection, it removes most contact points giving free flow for everyone coming off and going on the high way
DFW man, they just fucked that all up. Austin just has some old highways they can't really expand because encroachment, like I-35 just north of downtown.
Yes. I spent five years in the US and you mad men have your power lines above ground in tornado/storm prone areas. Had to spend two weeks without power in Bethesda, Maryland after a storm. Storm season has come every year in the history of your country, and every year the power lines get knocked out. Just bury it already.
Jesus fucking christ, why don't they make a fucking couple of roundabouts?
That's not a clover, that's better than a clover because the offramp is before the onramp.
Yes is it.
T. Bridge engineer and inspector
American cars can't corner.
you know liberals have hard-ons for trains
I love right off of this pleasant hill and I85 (which in other news collapsed recently), the design is brilliant for heavy traffic flow onto the highway where normally intersections would get blocked. This virtually eliminates the wait time for getting on the highway.
Not while they keep tipping over because of the drivers weight.
Need more roundabouts
Yeah well they're putting the trainlines only connecting the ghettos to the nice job centers, so its basically causing gentrification along the routes. Which is a good thing. Until gentrification is complete nobody rides the light rail because its full of druggies and homeless and niggers. Even in peak hours there will only be a few people on the fuckers.
Oh yeah and I forgot to mention then the liberals complain about gentrification.
They complain about white flight, then they complain when the whites move back. What do you fucking want liberals?
They want white people to die.
Mass transit will never take off in most cities for middle and upper class due to how disgusting it is to use from ghetto people and the mentally ill.
Yeah if they built the rail lines from rich neighborhoods to downtown and other job centers it would be full all the time. The way its done now its to ferry 5% janitors between work and home and 95% homeless druggies between begging spots and drug dealer.
Rich people don't want trains going into their neighborhoods. Nor do they really want to ride with the rabble.
crossing a lane at any point
getting off of the freeway
Why would you do that?
thats so stupid
so can someone redpill me on why you would have these monstrosities instead of round-abouts?
this makes me uncomfortable
Okay so why when they build light rail through the ghetto, rich people start moving there and gentrifying it along the rail lines?
NIGGER FUCK YOUR ROUNDABOUT BULLSHIT JESUS CHRIST YOU ARE PISSING ME OFF
my stomach hurts now
29.02.1916 - Arthur Hale receives patent for highway cross
Has a clear explanation been posted in this thread yet as to why this is preferable to two roundabouts that doesn't use Americanisms like "on ramp"?
Every time you have traffic merging you have a greater chance of an accident. Provided you know your exit it is super efficient, you get off one place and it merges you onto the highway you want. Those interchanges are running 55+ mph. All the roundabouts I've been on seem designed to slow you way down before you enter it.
Because they have firearms
construction blocks a single highway lane, requiring traffic to merge
Most American's won't wait paitently for that
so most won't wait to join a roundabout at an appropriate time and cut ahead
This would cause explosions of rage where ever a roundabout is located, resulting in asharp uptick of mass shootings
You are suppose to slow down so that you can stop and give way to any traffic currently on the roundabout, if you can see the rest of the roundabout clearly and nothing is approaching you can go as fast as you like around them
The roundabouts don't even have the same traffic directions
how is this good for traffic flow?
I'm serious, it literally made my stomach hurt.
Depends on whether or not your STATE is doing a good job. Fucking pathetic how gibmedat states have become, surrendering their autonomy and sucking federal cock for a dollar.
Zäh fließender Verkehr
Got to be honest I've never used one of these but those merging sections look so fucking dangerous.
We're talking highway interchanges not fucking intersections.
that red fucking car crossing over white line
Must be a sandnigger
I'm getting a boner
Americans can barely drive in a straight line, you give them this and half of them will be extinct via crashes.
God bless the Swindon magic roundabout
this is from where i live in brisbane
there is also a tunnel there somewhere, but you can't see it because it is underground
What cities skylines mod is this?
WHITE PRIDE ROADSIDE
There's a video explaining how they work:
From what I understand drivers were too stupid to turn into oncoming traffic without crashing to planners had to come up with a way to segregate directions for each particular turn in an intersection.
What the fuck is that retarded shit holy shit my sides hahaha
This is the best interchange
The solution is to have two different rail services: fast train and stopping trains.
The fast service only stops in the suburbs and central business district. The stopping services calls atball stations including the inner city stops where all the shitskins live. This way middle class suburbanites can commute without meeting any undesirables during their journey.
what are you proposing, a 12 lane roundabout with 20 exits?
The 4 crossing point on ramps are everywhere in Florida. I fucking hate them. You're always guaranteed to be stuck in traffic for 10 minutes if you approach one. The half clover design is so much better.
what the fuck is this mongoloid design and why is it being reproduced
are the jews doing this?
That's Houston circa 1960.
UK has spaghetti too.
There's I think only one of these in Ontario, off the QEW and Hurontario Rd. in Mississauga.
I always hated using it because merging was always a bitch.
No, it's fucking retarded because there's no free flow between the two roads and the roundabouts are always so congested they need traffic lights. The very concept you should stop at lights when moving from one motorway to another is on a level of stupidity only British designers could come up with.
I drove a lot in the US, had no trouble getting around except for some cities, LA is a hell with its busy traffic and potholes out the ass.
Hmm. So traffic is trying to get on the central roundabout at the same place that traffic is trying to get off?
what about when it gets busy?
On one of the roundabout junctions there are extended chevrons to split traffic flows up. The other three have traffic lights.
uk pretending their economic flexing can even be compared to the US's
