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 😁👍

[@juliahenriques210]

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.

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.

[@Trainfan1055Janathan]

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!

[@marikroyals7111]

Well when they have the nickname "suicide lanes" there might be a problem.

[@B-and-O-Operator-Fairmont]

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.

[@B1GDaddyFatStax]

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.

[@blanco7726]

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.

[@B1GDaddyFatStax]

@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.

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.

There's a fair amount of misinformation in this video. Diamond interchanges are not high traffic interchanges and generally can't replace cloverleafs. They actually support less traffic than a cloverleaf. Most full cloverleafs that are being replaced in the USA are being changed to partial cloverleafs (aka parclos)... an interchange type that's not even mentioned in the video... basically two of the leafs are eliminated in favor of intersections with stop lights on the non-highway arterial. The full cloverleafs that remain usually are upgraded to provide collector/distributor roads to move the weaving off the highway lanes or additional "braided ramp" bridges to eliminate weaving altogether. The cloverleaf was patented in 1928 in Switzerland.

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.

The cloverleaf is purposefully designed to make all entrances and exits on the right hand side of the highway (lets assume we are not in the UK ...). The solution to the "cloverleaf problem" is have left side and right side highway ramps for both entrances and exits. This solution is rejected by the state highway department designers because they reserve the left hand lane for express/carpool users.

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.

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.

[@UzumakiNaruto_]

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.

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.

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.
