I believe the default cloverleaf is in the game just to teach us how terrible of an intersection it is. It's realism: you threw it down in country without thinking, 30 years later its the source of your traffic woes and you need to fix it, but have no space because everything that developed around it.

In the Malmö area in Sweden, we use a lot of those cloverleaf interchanges. Traffic is quite low by American standards, so these intersections have proven to be safe and quick. I don't think I've seen a single accident during the 20 years we've had them.
You guys also have more modern ones which fix some of the issues presented, for example sperate slip lanes for the exiting/entering traffic to make the weaving problem less bad

As a truck driver, these off ramps are a nightmare! There have been times where I had to miss an exit because there was someone merging on and there was no way for me to get off without hitting them. These things are frustrating. And don't even get me started on merging on with a truck!
Well when they have the nickname "suicide lanes" there might be a problem.
Yes, and most of those old cloverleafs were designed for rigs with 35 or 40 foot trailers. And even the big "California Hauler" tractors weren't as long as some of the ones in use today.
Yeah, no kidding. California just makes it worse for truckers too. Limiting us to 55mph and keep to the right two lanes. Not that I'd wanna hit a cloverleaf any faster that that. It's the speed differential that causes so many accidents and as she mentioned in the video....merges. you get dingbats coming onto the highway at 35mph and slowing down ON THE FREEWAY to exit too. It's like playing dodgeball with the player being 80,000lbs, dodging a hundred balls. I hate trucking in Ca.
Joe's Garage one intersection in my country kind of fixes this by putting a quick zig zag turn between where you get off the highway and where you cross with those getting on. This forces everyone to slow down to around 70kmh which makes it a lot safer when traffic isnt high. But it also causes slow down to back up onto to high way and when it’s traffic is higher.
@EmperorJuliusCaesar , I'm not disputing whether slower or faster speeds are safer. The issue comes from the speed differential between slow moving trucks and other impatient drivers causing the two worlds to literally collide. I even mentioned that in my comment. Someone has already been looking into this issue. Here's an article from 2006 outlining the highlights of said study.
www.insurancejournal.com/news/national/2006/03/22/66692.htm
Another argument can be made for hours of service. By slowing truckers down it limits the distance they can travel in a given amount of time, requiring the hiring of teams and jump drivers etc. This cuts into profits for drivers and companies alike and ends up being passed along to the consumers.
Now, on the flipside, driving slower does decrease fatalities by lowering impact speeds. Reaction times are also improved at slower speeds. Hydroplaning is also reduced etc.
So, yes, slower speeds are safer. However, this comes with a caveat. It's only safer if everyone is driving the same speed. When you have up to 20mph speed differentials among motorists competing for space on the choked highways, things can end up just as bad as everyone doing 80mph.

Cloverleafs were built for a world when people still knew how to merge.
They are built and standard in places with better driver education.
The German Autobahn uses nearly exclusive cloverleafs for it's full intersections.
at a time that not every household had 2+ cars
I mean still, there’s inherent problem with having cars speed up and slow down in the same lane.
@@triple7marc Not really, they both try to reach about the same speed.
Educated drivers know that you go near full acceleration once you enter a motorway and for leaving you break only when you're on the off-ramp.
This "problem" is mostly a problem of ego and bad drivers that don't want it just can't work together.
They were first designed for vehicles that didn’t go as fast as today’s vehicles. They were designed for a world where cars could go 80km/h but now Suzanne’s Ford Focus can go 200km/h
I wonder how the cloverleaf compares in different countries. For example in Germany, in driving schools we are taught how to merge/join on cloverleafs and (though I rarely drive) I've rarely seen the accidents you described.
Welcome to Germany
maybe yours are outside of cities and have less traffic
@@anteveic327 no
@@anteveic327 no it's the technique called the "zipper technique" it's a very simple rule for merging. Drive to the end, do the zipper. Here in America where I am they just merge without adjusting speed, everyone merges at the same time, it's a mess! But we were never taught the proper technique. We don't even set our mirrors correctly in most cases.
I get the feeling that people in Germany actually care about being good drivers and helping traffic flow well. That would be the difference.
Is it true that at stoplights in Germany, the whole column starts moving at once when the light turns green, rather than one at a time...?
9:13 "Engineers could have never anticipated the massive boom in ... vehicle use." Uh...yeah they could. There has been a constant effort since the 1920s to rip up trams and other forms of public transport in favour of cars. Saying you could've never anticipated what people were consciously working toward is like saying, "I turned the stove on, but then it got hot for some reason."
Many don’t know this.
Corrupt politicians, bribes and all, is why America doesn’t have a speed train like Japan, or fancy affordable public transport.
She also first said;
“We didn’t expect population boom”

As someone that doesn't even drive
I've recognized this "weaving" issue simply by observing my city
In the UK we have something more popular called a "partially unrolled cloverleaf junction" where two symmetrical loops are turned into right hand slip roads that run parallel to each other. They are useful because there's no weaving, they take less space and only minor traffic uses the loops. There's one on the M25/M40 junction
I knew I recognised that design, I live near and have used the M25 junction.
They look like a owl too 🦉
That would be known as a "cloverstack". Half stack, half cloverleaf. This eliminates all weaving. The reason to go full stack is for higher speeds.
Plenty of time you also see three parts cloverleaf, one part stack/turbine. It still has a weave, but perhaps that direction is not so busy.
That's the design I see in Austria.
Great video, very interesting. As an avid Cities Skylines player and traffic fixer I can see how this design, whilst good to start, soon crumbles as car flow increases. Whereas there's tools and tweaks in game that helps things flow better (lane mathematics and dedicated merging lanes), sadly this doesn't solve IRL problems as well. Thanks for the video 😁👍
It is the almighty fixer of traffic
They better hire you as a consultant biffa for an ocean of tea
In a way the loop ramps of a cloverleaf are basically just a wacky looking roundabout
This. If you could turn traffic accidents on, it would be an entirely different game. It's pretty much impossible to manage without an AI that makes full use of available lanes, though.
Also, thanks for the invaluable tips to game the AI into doing what we want. I like to go for organic rl like planning, and at first I didn't make those fine adjustments for the AI to "get it". Now that I have a fully grown city (all 9 sectors developed), I'm going around Biffa-ing the traffic to try and get to 90% flow.
The one real life solution you never use, though (mainly because there are no traffic accidents) is to actually progressively decrease the speed limit before the busiest spots. If they don't have to abruptly slow down to turn or merge, there's no bunching up. Fluid dynamics: slower flow makes less waves. It also applies to traffic. It's completely counter-intuitive slowing down to flow faster, but it works like a charm in real life.
BIFFA HERE TOO?? SalC1 is in these comments aswell
"Engineers could not have foreseen population growth". Meanwhile, in my neighborhood growing up, we had a lot of engineers who had 8-10 kids.
Yeah, and chances are, they tended towards Creationism, and really did only plan for steady-state population for some reason. It's like surprised pikachu faces all around when they realize that the population bomb is all too real. But oh, make sure you don't notice, make sure you support mass immigration, and make sure you keep feeding the turd whirled. In the 60s and 70s it was use birth control. Surprised pikachu faces in the 1980s when "Western populations are falling!1! Need immigration!" and now "why iz there long wait linez in ER ..."
@@LaikaLycanthrope what
all the kids were surprises lol
😁😁😁
@@LaikaLycanthrope 1) the population bomb theory has been proven wrong. 2) plenty of traditionalist/fundamentalist Chrisitians believe in evolution (if that's what you're getting at). For instance it's established Catholic doctrine that it's okay for a Catholic to believe in evolution; also the scientist who led the human genome project was an Evangelical, and he interpreted the Book of Genesis rather differently than you might expect.
The classic "are the gonna try to go in front or should I....." while traffic still wants to do 80
Rule of thumb: a car exiting from the freeway onto a ramp brakes, a car going from the ramp onto the freeway accelerates. When two cars "block" each other, each driver should just do what's natural, not the opposite.
Road capacities still matter. If you need to having multi-lane ramps and multi-lane merges, cloverleaf intersections need to be replaced with other designs.

Personally, as a layman and not a civil engineer, I found the argument about why Cloverleafs don't work was well laid-out and built-up over 10 minutes, and I wish it lasted a little longer, even, to explain why the alternatives (like Diamonds and Directional IC's) solve the problems that Cloverleafs can't.

That's where she got the idea for this video. (In other words, she 'stole' it.)
fortunately, in CS, it doesn't take millions of dollars to upgrade an interchange.
Fyi: I hate them in real life too.
A clever solution for the cloverleaf without weaving is found in Germany, right east to the Frankfurt Airport. A cloverleaf without weaving, because the exiting lanes merge inside the loop. There are 2 reasons why this solution was chosen: 1. located at the end of the runway, a construction up in the air was not an option. 2. lowering the intersection was not possible, because a train tunnel runs underneath it.
There’s a really small cloverleaf interchange in Columbia South Carolina that was built in the 1970s and a bunch of houses and businesses built around the interchange. Except the interchange is between two interstates. Due to the homes and businesses, it can’t really be expanded. There’s so many accidents there that the locals have named it “malfunction junction”.
The Cloverleaf...also known as the Cloverfield because of how much a monstrosity it was.
to be fair, those directional intersections look more like monstrosities
@@TVegaC In El Paso, TX the directional interchange between I-10 and the "Patriot Highway" (US 54) is called the "Spaghetti Bowl" for obvious reasons.
It’s also known as a clover field because you could have fifty farmer’s fields in the area that one cloverleaf interchange takes.
when there are driverless cars that communicate with eachother these will be great.
I thought would be because of the ammount of luck you must have to manage a traffic with them. But still works

Increasing traffic capacity is making everything worse. You need to decrease it.

No, they don’t “work fine”. It’s not an American thing - the whole design is broken precisely for the reasons mentioned in the video. They are okay (at best) for two roads with moderate traffic, but as soon as either one gets busier, the design can’t cope.

I loved them as well for an engineer who saw them for the first time in Dubai. We didn't have cloverleaf or any form of interchange in our city back home in Philippines.

Oh wow, so that weaving problem is the issue I’ve always had with cloverleafs, in city simulators I’ve always ended up needing to change them for other interchanges due to reduced capacity and weaving is the cause. I’d found myself making weird cloverleaf derivatives where I could have the slip lanes join on the opposite side to avoid the issue but it never hit me how it worked.
I think my local city planners need to watch this, I'm forced to weave way too often.

Ok i wasnt the only one that caught that
Bad writing and editing. Was this written for middle school??
I can remember when, at least here in the South, you’d sometimes run up on a cloverleaf all of a sudden, on an otherwise 2-lane highway. I guess most of them were built before the interstate system was complete. Later, I found out they were a popular solution when intersections in rural areas had a high rate of accidents. Dividing each highway for a one mile stretch and installing a cloverleaf was an ideal solution. In that setting, it was not really possible to overrun the interchange’s capacity, and accidents would almost completely stop.
What slays me about the cloverleaf is that you can reverse the order of the ramps so that you aren't merging INTO THE OFF-RAMP when you're trying to get on the on-ramp, but that so many of these were built essentially to ensure a rough stop right at the beginning/end of the ramp.
cloverleaf is an inside out roundabout. It favors through traffic, while roundabout favors right turns traffic. Both have capacity relative to turn radius.
The difference is that cloverleafs allow traffic to flow freely whereas theoretically roundabouts force all traffic to stop.
@@joshbostock4371 You mustn't get out much.... or you're American. You slow down a little for roundabouts - except in Italy or Sydney where you speed up.
It's a give way, not a stop.
Many motorway/dual carriageway junctions in the UK are raised or sunken roundabouts. Through traffic continues freely while only traffic that wants to turn needs to enter the roundabout.
Warwick Carter if there’s traffic in the circle you can’t just plow through them buddy.
@@uhohhotdog Merging into a roundabout is about timing and giving way - not stopping unless absolutely necessary.
If you're always stopping you're doing it wrong.
If traffic is backed up inside the roundabout then there is a downstream products on one or more exits. Queuing axross an intersection - roundabout or not is illegal in most places I've driven , even whrn there's congestion.

They seem to work just fine in Germany, a few high traffic interchanges got upgraded, but the cloverleaf is still by far the most common variant.
Germany isn't as auto-centric as the US. Far more people use public transport over personal vehicles.
Germany's autobahns ends at the urban boundary, they dont cut through the urban downtowns, at least not to the extent that highways in the US does.
Tao Liu
To be fair, when the highways in the US were built almost none of them went through Urban cores, everything just built up around them.
From what I've seen of German and Dutch cloverleaves, the lane where the "weaving" goes on tend to be a lot longer allowing the traffic merging in and out to do so at the same(maximum) speed of the lanes next to them, which helps a whole lot.
Also, let's be honest, it's a lot harder to get a license over here.
Certainly more space available.Then again, who wants to live right next to that.
There's a cloverleaf in Woburn, MA that the state highway department has been debating on how to fix for decades now (hint: can't be fixed without taking land)
Good job stretching this to ten minutes. I didn't think you'd make it, but you found a way!
I wonder what a Venn diagram of folks that can't merge and folks that can't parallel park looks like!?! I'm betting there's a ton of overlap.

Funny how when it's a program to help us the numbers are stated in 10 year increments. The military budget for instance is only ever discussed in "per year"

@@johnperic6860 Congress doesn't have budget control over welfare. Social Security, unemployment, and Medicare spending are allotted money based on the amount of their use.
If you want to "cut" those, you'd either have to ensure that people don't need it to survive, thus reducing the spending on it, or youd have to maliciously leave society's most vulnerable (children, the disabled, elderly, unemployed) without any safety net whatsoever.
This fact is why the Republicans always talk big about welfare overspending but never actually cut it down. They don't have the power to.

And the oldest thing similar to a highway Is the general Paz, built 1938. WTF
There is this cloverleaf interchange near me where two interstates, I-44 and I-49, and a state highway, MO-59, intersect. I-44 goes across east-west. I-49 comes from the north and then switches to the west and becomes concurrent with I-44 for a couple of miles. MO-59 comes from the south and ends at the interchange. This causes issues because those coming from the west and want to continue on I-49 North have to use one of the leafs, while those coming from I-49 South and want to go to I-44 east have to mangle with the large amount of traffic that want to go on I-49 North. I had a close call with a 18 wheeler because of the fact that the exiting traffic and entering traffic have to use the same lane, and the fact that the entering and exiting traffic can’t go fast and this causes other issues with other vehicles traveling fast. This interchange was built when I-44 was being constructed and back when what is now MO-59 and I-49 north of the interchange was a single lane highway known as US-71 Alternate. So there wasn’t any issue back then, but now for the past 20-30 years, and I-49 being recently added, that interchange is a mess. I don’t believe that MoDOT will replace the leaf with a flyover for northbound I-49 traffic, because a couple miles to the west, I believe that they are planning to replace another state route, MO-249, that is already built to interstate standards with I-49. So I believe that don’t see it worth it to modify the existing ramps if it’s going to be obsolete in the future.
One interesting design I've seen in England is through highways separated by bridges while the on and off ramps join in a big roundabout.
Common in Sweden to.... but US do not know what a roundabout are....
not uncommon for intersects where different road categories meet - but the US don't like roundabouts ;)
Thought you were going to mention Swindon's Magic Roundabout. One large roundabout made up of many small roundabouts.

Build tunnels instead.

A well presented video that makes a seemingly boring topic fun; intelligent AND gorgeous presenter; and mentioning city-skylines... how can it have less than 1 million views...
Only 3 full ones of these were built and only 2 are left. The third got replaced with a double roundabout set up with only 2 of the loops remaining.
Oh my golly!!! I've never seen a video that was so obviously stretched to 10min of runtime. You can watch it at 1.5x speed and it still sounds normal!
RUclips only allows video monetization in videos above 10min.
They changed it recently to 8min. so they will probably make shorter videos.
Well specifically midroll ads. You can monitize short videos but not as much.
I like her voice and use cheddar for background noise tho so no complaints here

You definily should know Brasília, Brazil's capital. The whole city was planned in the 50's and pretty much based on those cloverleaf (that got the nickname of "tesourinha" here, in a literal translation a "little scissors"). And land here became extremly expensive.

It’s funny, I saw Road Guy Rob’s presentation of a case study for what to possibly do about one of these in Salt Lake City (looking at the maps app to refresh my memory, it’s I-215 at UT-201)

"It was invented by an American who stole the idea from a nameless Argentine"
"The story of this invention starts in the US, and not in the country where it was invented"
"This invention has only been tried and tested in the US"
This is why the world thinks Americans are cute.
Thought the exact same thing, they act as if it was an American invention.
So where was it invented from?
@@copperdan1275 Be smarter.
Not a new thing, US just steals ideas and make it seem like they invented it.
Exactly, the research into the origin was so poor, “some guy stole it from some place in South America why? Idk it looked cool”
I wanted to know the thought process behind the Argentine engineers decision to build one in the first place, the information they they gathered and how they implemented.
Weak video
Inner leaves essentially create the problems that left turns do via entry/exit weaves. The primary solution to the obvious speed impediment is to have the inner exits at a different grade and a merger point after the next exit- which creates clearance and cost issues.
There's an exceptionally tight cloverleaf near where I live, in a suburban area with heavy commuter traffic. Each freeway is reliably trafficked at about the same times. Worse, it has exits and on-ramps very close respectively before and after it in three of the directions. I learned to drive freeways partly by repeated, harrowing trips on it. I can only imagine how long ago it was a sensible interchange for the traffic it supported. There's an improvement project for both freeways ongoing; I rather hope some kind of fix, or easing, of the cloverleaf problem there is in the works.
When you have those side lanes just for the entrance/exit they work a ton better. I'd say as good as anything else I've been on.
@@asificam1 I'm in Winnipeg and we love cloverleafs lol Just wait if you travel east,we plan on putting a roundabout on the Trans Canada. No joke!
Thats the way it should be.
I personally call it “the pretzel loop interchange”. 🤷♀️

@@entonduck every region have their own names so yeah it doesn't matter
considering nearly all german Autobahn interchanges are cloverleaves, it kinda fits
Hard to describe in words, but you can have a look what they do in Germany now very often with cloverleaves: you block lane changes in the intersection,e.g. by a small wall, and then built a small bridge over the leaf of a cloverleaf. So after you took a leaf, you don't change lanes, but drive above the other leaf and then merge in your direction. You cannot do it with too much speed, but it is surprisingly efficient
There are stack interchanges all over Texas urban areas, we don't deal with cloverleaves very often. Though the Waugh Street and Memorial Drive intersection in Houston is a notable exception.
They really just photoshopped a road onto the intersection in the thumbnail
One of the ramps is cut short.
@@tompeled6193 If you look at the thumbnail someone poorly photoshopped a ramp into the picture

All countries do that, it's just that the USA does it slightly more often and blatantly than the rest of us. This was particularly true back in the days of the aformentioned article.
Kinda like the discovering of America.
In Belgium we love cloverleaf interchanges :-) where land is expensive and bridges are cheap
I'd like to see more usage of diverging diamond interchanges. Especially interchanges between a semi-divided highway and fully divided interstate.
Diverging diamond is a service interchange (getting on/off highway), similar to single-point (which is better than DD in alot of ways). Cloverleaf is a highway interchange (between two highways). DD is not a feasible replacement for cloverleaf because one of the roads would not have enough throughput.
@@razaelll Great. I didn't suggest two fully divided highways. I suggested a semi-dividend highway (45 or 55 mph speed limit) to a fully divided highway (55 to 70 mph speed limit).
A standard diamond interchange is used here all the time. With left turn lanes in the median of the semi-divided highway.
In the Netherlands we have a large amount of these weaving entry-exit lanes, sometimes being very short. You get taught how to negotiate them in driver’s ed, and because everyone’s taught quite well, you almost never run into problems. It’s not the road structure that’s at fault here, it’s your driver’s ed that’s incomprehensibly limited and unconstrained. Weaving isn’t hard when everybody sort of knows what they’re doing.
Its both. Even if you have no problems negotiating the weave, it still slows down traffic and there's still an increase in the chance of an accident where if you didn't have these weaving entry-exits you could get rid of both problems.
I just fucking hate the bit between Feyenoord and Ridderkerk southbound on the A16. I don’t know what drivers education you’re talking about, but clearly everyone suddenly forgets everything about proper weaving as soon as they approach that section of the Rotterdam ring road.
Funny how "Went off" and "Turned on" are the same thing when referring to metaphysical light bulbs.

As someone who does play Cities, I discovered this issue rather quickly and began using elongated 'H'-shape off/on ramps with frontage roads. It's more expensive to put down and maintain, but traffic flow is much smoother.
Main problem with cloverleaf is the difference in speed. These were designed in the 1900s for cars that barely even go 45mph. Nowadays cars can easily travel at 100mph without any issue. The people merging onto the highway don't have the ability to go 30-70mph in 2 seconds given the short length of the merge. Meanwhile, people exiting are given a very short distance to brake from 70-80mph to 30mph.
Anyone else have to play at 1.25 speed? Sounds like she’s speaking in slow motion

At :31 she said that cloverleafs were build to allow two highways to cross with out traffic lights and harsh left or right turns but when she mentioned the woodbride interchange update, it added 2 traffic light, harsh left/right turns and and a dangerous crossing when turning north from the St, Georges AVe. in to road 1.

Boy, Cities: Skyline sure does get a lot of love, and deservedly so.
And thank god SimCity is rather hated now.
Cities Skylines Gang where are you?!
Enjoying a roundabout.
Icespoon nah I prefer my one tile wide stacked interchanges... and also Roundabouts destroy my perfect inner city grid with traffic James that I try to resolve with timed traffic lights 😬
I usually use roundabout. And I have tried 4 layer stack interchange and it's not very different from the cloverleaf.
I suddenly have an idea to quickly fix cloverleaf loops.
Simple switch the placement of entry and exit by extending the exit/entry bridge. This would fix one of the biggest problems of cloverleaf loops
In my local area we only use half clover leaves as mostly on ramps.
This video brings back memories... of my friends and I taking bong hits driving on the cloverleaf. It was fun. I just looked up Google Earth to see the cloverleaf in question, and its gone, replaced by a partial cloverleaf like in the video. The march of progress destroys more of my youth.
you can fix weaving in cloverleaf interchanges by separating the on and off ramp into a slip lane so the on and off traffic go into a single lane. Alternatively although Ive never seen it done is to pass the offramp over or under the on ramp so they don't even share a lane at all. It makes much smaller bridges and tunnels than doing massive flyovers.
flyovers are great. Both as engineering marvels and fun to drive.
@@michaelbruvolt4221 just expensive.
“one more lane, bro”
There is one in redditch, near where i live and its quite uncomfortable to be on but there is low traffic so it works there

I see what you did there....
I have a similar problem where I live in Barcelona. Two highways cross and as a result of that I have to switch highways and immediately afterwards cross 4 lanes to leave the highway in the first exit after that crossing, which is especially dangerous and scary if you're riding a motorcycle. On top of that most of it happens in a tunnel
Informative video.
Just two suggestions: 1) “The lightbulb went OFF” - I would suggest it went ON.
2) perhaps educate the drivers to merge better might be cheaper than building tunnels and flyovers?
Educating people? You for real? 🤣
Educate? Ha! US states are making laws that FORCE drivers to move over so the oncoming cars DON'T HAVE TO MERGE.
It's disgusting. 🤯
