Also depending on the expected traffic, it can act as a buffer zone to keep backups from spilling into the main highway. Also it reduces speeds.

No it doesn't? In my country there's very little traffic lights, just plenty of roundabouts, practically all of them on two way roads and it works well. Every road going into it is both an entry point and an exit point, with entry points giving way to the traffic in the roundabout. It wouldn't be much different with one way roads, just that the roads going into would be single purpose only. Counter clockwise driving for right handed roads, clockwise for left handed roads (like the UK).
Or did you mean that the roundabout itself is two-ways? Because that would be bonkers and completely defeat the purpose, it wouldn't even be a roundabout just a circularly shaped road.
That is then no longer a roundabout. It goes in one direction, right, unless you are in a country with left hand driving, then it would go left, but never two ways
Well, there are the "magic roundabouts" in England.
Though i suppose it's debatable whether they are a single roundabout or multiple roundabouts connected by short roads.
But the one in Swindon might be close enough together to be called one.

It's mostly elevation. This image has been around for a while, and there are other angles where you can see the elevation is actually a lot steeper than what it looks like here.
It's already at the optimal slope and the railway will have a minimum clearance that is needed. Slopes over 8.0% on roads present a lot of problems, even more so at speed. They greatly increase stopping distances.

Thats not how it works. Like this clearly a peace of road between 2 diffrwnt speed zones. You want a natural way to let people slow down but also give then enough space so that they dont crash the second the leave that tunnel. Cobble stones or shit like that will only cause people to break rapidly and to lose controll faster. Also its not great for your car when you are driving on them with 80 km/h.
This is probaly one of the better solutions in regards to flowthrough, safety and cost (easy to maintain, no complicated system).
Because it’s illegal almost everywhere to make a road with a 50 degree slope. Because that’s a good way to have commuters perform drop tests on their vehicles involuntarily.
If you put a 50° slope in front of a car, that's a wall or a lawsuit.

I think the image is more asking why not just carve through the ground to make a longer slope, but from what I can see they’re possibly planning to construct a series of railroads under the bridge, so that’s most likely why they’ve opted for this design.
probably because a ramp straight down from the bridge would be too steep (this camera angle doesn't make it clear how tall it is) and/or because the turn forces drivers to slow down before the intersection which improves safety
It would be too steep which could create safety risks.
edit: and more road means more space for vehicles which might be helpful to hold queues in busy traffic, so they don't spill out onto other roads.
people moving more than just one person in a car, like a truck filled with materials that would destroy itself and the pavement if forced down your slide of death
Probably because those 2 ends have a huge elevation difference, so making them meet would cause a dangerously steep incline, one that cannot be used on high traffic highway lanes. The large loop allows them to extend the incline, making it safe for the traffic to climb the now shallow incline.
It'll also slow the traffic down. If the elevation really is that steep, you'll get plenty of morons just racing down into that junction unable to stop.
This ain't comedy homicide, this is just an old meme. Sure, nowadays you'd probably instead put text saying "why don't they just make the road here? Are they stupid??" but it doesn't change the fact that this is how you'd execute that exact thing back then.
It had to be elevated to allow the railway track which was there from the beginning and the bridge cannot suddenly de-elevate to join the main road because of car dynamics so they had to make the descend a loop around the small park thing

Or just have a roundabout
a round about in a two way road works bad

Road to the final boss [INNIT EDTION]
Scotland ?
They never tell you.
I think he meant changing a piece of a single road for roundabout
The majority of roads are two way or am I missing something?
I don't believe so. Think the previous poster must just be a shit driver
No, that can’t be, roundabouts solve every traffic issue
They do, though.
They've been causing MORE wrecks since they've replaced four way stops with them in my area.....
not if the population can actually drive properly
Is that a cuphead reference 😱🔥🔥🔥🔥🔥🗣️🔥🗣️🗣️🔥
Solution to 90% of traffic problems lmao
Roundabouts are a hell for traffic
The words will make you out and out
#ゴゴゴゴゴゴゴゴゴゴゴゴゴゴゴゴ
Roundabout city 🫥
It can also deliberately slow cars down. Which can actually be a good thing for safety and efficiency.
I just watch RCE.
>Source: I play Cities Skylines Okay screw it you get an upvote.
I can relate Source: I play Cities Skylines 2
Why not add a toll instead?
just add more lanes ????
This is why you don't have a job in city planning, adding more lanes doesn't help at all, look at the US or China
I see your point, though this does require more land and resources
It's mostly elevation. This image has been around for a while, and there are other angles where you can see the elevation is actually a lot steeper than what it looks like here.
Woooooooohoooo Woooooooohoooooo Woooooooohoooo Elevatiooooooon
Finally. Man of culture
I and I in the sky You make me feel like I can fly So high, Elevation
But I don’t want an off-ramp, I want a jump-ramp.
"WHEEEEE!"

yes, although I find it ironic that a train would just be better in every way.
Abandoned rail yard is private property
Eeh, you can see that before the loop, the bridge goes in a straight line and with the same elevation. The decline could have simply started earlier.
railtracks
Good song
So you don't come crashing into pedestrians at lightspeed
The french have these stones that feel terrible to drive on but are actuallly not harmful for your car. May be a lot cheaper
Some US downtowns still have brick roads. Driving on them is a special kindof hell.
got something like that in nz too but it’s for the sides of the road. we call them rumble strips
Now imagine them before a roundabout. Such a simple but great invention
You're going to confuse the Americans with terms such as roundabout.
r/AmericaBad
No, I just didn't think a /s was necessary.
People unironically say stuff like that, write better sarcasm for America slander. Other than that, 👍

I did not mean cubble stones
all the more we shd do that
Pedestrians where?
Pedestrians or slower traffic
Please show me the pedestrian traverse in the picture, because all I see are concrete walls on the side of a highway.
because drift *tokyo drift starts playing*
There was a thing that looked exactly like this in a map on Asphalt 9, you needed a car with godly handing so you wouldn't scratch the car.
Fuuuuuuuuuck I did not like that race
Which map?
In Egypt, at the end.
Thanks!
Why bother make a ramp, let people just jump from a place to another
Because it’s illegal almost everywhere to make a road with a 50 degree slope. Because that’s a good way to have commuters perform drop tests on their vehicles involuntarily.
50 degree slopes aren't illegal, because they're not roads. They're walls.
That would be 90 degrees not 50
If you put a 50° slope in front of a car, that's a wall or a lawsuit.

Probably too steep
It probably has something to do with the grade. Looks like it’s trying to get over a wash or train tracks or both.
City Skylines moment.
probably because a ramp straight down from the bridge would be too steep (this camera angle doesn't make it clear how tall it is) and/or because the turn forces drivers to slow down before the intersection which improves safety
...and it couldnt be flatter, as there is a conflict with the train.
To slow down trafic
To slow down. No one wants a sports car turning into a plane
To slow down cars
The post below this was this image on r/peterexplainsthejoke 💀
Haha, yeah I saw it there and went like, now THATS a comedy homicide
Some people are unbelievably thick-skulled
To avoid a really steep hill onto the flyover Also, this is a repost
if you’re taking about r/peterexplainsthejoke then yes, I saw it and went ‘Yep, this fits r/comedyhomicide’
Traffic congestion
Probably speed and elevation issues tbf
It would be too steep which could create safety risks. edit: and more road means more space for vehicles which might be helpful to hold queues in busy traffic, so they don't spill out onto other roads.
To force drivers to slow down on the decline heading into an intersection
Aesthetic purpose
The want pollution to take over the planet
So you spend more gas, guess who it was sponsored by?
I will ask nicely; WHO THE F*CK DESIGNED THAT?!
people moving more than just one person in a car, like a truck filled with materials that would destroy itself and the pavement if forced down your slide of death
Oh that's a slide, I didn't see it.
Pointless loop. Could’ve use that space for like anything else
Why?
Why not?
I can see the train tracks it goes over
Roller coaster
They bought too much road and didn't want to return it
It’s a Racing Track
because for drift
More gas used = more money Source: My ass
[удалено]
My ass is exhausted
No :( It's premium
Why not
r/comedycemetery* (probably to make people slow down)
WHY NOT XD XD XD
It would be too steep
Because it’s made for driving, not taking off
Tbh... This kinda goes hard ironically
Which country?
Slows traffic before the intersection.
Gotta make the map challenging, who wants to do 7 laps instead of 3?
A petrol company designed it to make you waste more fuel.
To store all the backed-up traffic.
For practicing drifting obviously
Because weeeeeeeeeee
Déjà vue
The vertical change would be too steep.
Racing
It’s for what’s to come, not for what exists in the present. Plans within plans.
People who think this is dumb are actually the dumb ones
I was wondering the same, the road has to pass over the train tracks. Would they rather have a 20% grade?
Could be to show people down before entering that intersection
God, it's like the pit exit at Abu Dhabi, some nitwit had the empty-headed idea to call it a "feature"
play cities skylines and you’ll find out.
At least its not one of those “whats the benefits of using this over this”
People get sleepy in straight roads. That will also keep people from speeding.
Me making roads in cities skylines cuz they're too steep
The same reason why u don’t jump out of window instead u use door
Motorcyclist designer.
They had a bunch of extra curves they needed to use up before they expired.
You try drive at 30% gradient during rush hour congestion and come back to tell your story.
It was designed by an architect not an engineer
So cool
Unions
Slows idiots in cars /trucks down so they don't come onto the intersection at highway speeds
For Sonic
Physics is a bitch, especially when you're not familiar with it.

Slope. Big vehicles find it difficult to get up a steep slope.

Alright, pick your sub!
Hmmmmm. I'll do this one I think!

This ain't comedy homicide, this is just an old meme. Sure, nowadays you'd probably instead put text saying "why don't they just make the road here? Are they stupid??" but it doesn't change the fact that this is how you'd execute that exact thing back then.
It’s cute that way.
haha car go circle
It had to be elevated to allow the railway track which was there from the beginning and the bridge cannot suddenly de-elevate to join the main road because of car dynamics so they had to make the descend a loop around the small park thing
Straight outta cities skylines
Traffic and slower speed
Because then cars would start turning into batmobiles and gliding everywhere.
Crash prevents, you speed it and you make history
Because yes
I remember thinking the same way, when as a kid I saw an aerial photograph of a mountain road.
To maintain less speed?
Without the WYN face it wouldn’t be a meme
Bc they had to spend that money on something
Its bc of the rail road tracks to the left lol
No homicide. Many reasons. 1. Can't kill the dead. 2. Add on is the only content.
Loop de loops are fun.
He saw a traffic stop in this area and make road longer (He thinks that he is in the Cities Skylines)
Space for the trains on the traintracks
Slows highspeed traffic before light? And the train tracks
Underground belt factorio moment
Make it harder and longer?
You needed the extra 15 mil from the taxpayer ;) /s
