Being from Michigan, the Michigan Left is the best. If there isn’t a large amount of traffic on the secondary route, you can basically avoid ever “needing” a traffic light which keeps everything moving on the highway.
0:55 base game u-turn pog! 😮This was my favorite intersection from your CS1 videos. I got to build it in a fully functioning city only one time and it wasn't very successful, but I love the concept.
this makes so much sense. I always tried to eliminate the u-turns I have coming from a 6 to 4 road but now I know I can just extend the 6 lane road to a place where a u-turn makes sense.
These have been my go to initial service interchanges when starting cities; it takes a long time for traffic volume to overload these, and their footprint is so small. Plus, my hometown uses these a lot so it's kinda nostalgic
You may have already made a video on this but im surprised it wasnt talked about in this video. In my opinion the New Jersey Jug-Handle is the best solution to the left turn and U-turn issue. Essentually all turns are made making a right hand turn. There are lots of examples of this on The Black Horse Pike in NJ for example.
Hey there, Traffic Lights Enhancement Alpha by slyh is a currently working solution to give intersections multiple phases. It offers 3 way split phasing, 4 way split phasing, advanced split phasing, protected left turns, a pedestrian exclusive phase, always able to make right turns an option, and the ability to do lane specific directions. Really helpful, hope you find it helpful as well!
I always enjoy telling this story... My parents divorced in 1994, when I was 9 years old, and my mother moved to Michigan while my father stayed in Florida, so I spent at least 90 days of every year for the rest of my childhood and teenage years in the Great Lakes State, and I now live here permanently. I'm quite familiar with the Michigan Left. My father... not so much. When my sister graduated from college -- which she chose to finish here -- my father and stepmom naturally came up for the ceremony. I was riding with him the very first time he encountered a Michigan Left. Now, you have to understand, he's a pretty conservative guy in his language. I don't think I've ever actually heard him swear. But after I explained to him how to navigate that intersection, his response was a knee jerk "WHO THE FU-- WHAT IDIOT CAME UP WITH *THAT* IDEA?!" To this day, he denies all knowledge of that moment, but it's seared into my memory! 🤣
As somebody who, despite not being from Michigan, despises making left-hand turns whilst also dealing with traffic congestion (such as during rush hour), I appreciate you covering this topic. Though Michigan has long fallen from grace, I nonetheless do like their innovations in traffic management. (That and I'm also fond of Detroit-style pizza.)
The last option with the diamond is something that I have been trying to promote for a couple of years now. I call it a DAMN interchange; Diamond Accentuated with Michigan left/Median u-turn Nearby. I think that like you said it is a good idea for an interchange where you can remove traffic lights to increase flow rates as long as the right turns are protected from oncoming traffic via some traffic island. But it isn’t good for large volumes of left turns.
YUMBL: It's also a "Seoul left." There are no left turns allowed in Seoul proper. If your destination requires a left turn, you have to pass it, take the next U-turn, then turn right into your destination. I lived there for several months back in the late '90s while touring with a band, in Gangnam Ku (yes, the Gangnam Style neighborhood, ha). The arterial that ran in front of the hotel where I lived was TWELVE LANES. Insanity.
When you make it an interchange you can do a reverse RCUT (RRCUT?) where the left turns exiting the highway ramps can proceed at a traffic light but the left turns onto the highway have to do a U-turn (rather than the other way around). That neatly avoids the game's issue with giving permissive left turns at traffic lights by default.
There was a street I used to travel a lot that was interspersed with MUTs and ParClos that was actually really fascinating for how fast it got traffic through a busy shopping area. I wish it was something more UK cities would implement, because it's a very clever solution for an area with limited space for expansion.
Three phase lights are possible! The issue is that your minor roads cannot line up! So if you were to make a 4 way intersection, if two of your roads going the same way (north-south, etc), make one road enter the junction 1.5 or more units from the other road, and they'll each get their own light phase. Might work for the main road too.
Around here a typical solution is a three-phase light without turning around shenanigans. The major road has a separate phase for protected left. The side roads have conflicting left turns, but this is rarely a problem due to low traffic volume.
A variant of this is used on the M2 expressway in Adelaide where it intersects Port Road. Traffic coming from the freeway/South Road must turn left and use dedicated U-turn bays to turn right.
I first encountered the U-Turn Left in Michigan when I came across an intersection where the cross-street was at an extreme angle. The angle made left turns from the direction I was traveling nearly impossible. The U-Turn Left was the solution. It pulled the 'left turn people' out of traffic with a turn lane after the intersection to make the u-turn, though. The bowtie in Kalamazoo was very effective, too. What if you combined the bowtie with your last example? :P Awesome vid!
IRL this is probably the most cost effective/ least disruptive to implement especially in the outer sections of a city with moderate traffic like arterial crossings leading to highway connections. I've also seen it in older neighborhoods in europe, where traffic increased over the years and roundabouts weren't viable.
The final design you made is effectively a compressed version of the large roundabout ones that we get here in the UK, We often get slightly ovular roundabouts that use 2 bridges to cross the motorway, (straight bridges) with entry and exit ramps on and off the main motorway, and normal roundabout entrances for the other connecting roads, The main advantage of this is it allows more than two roads to be involved and this style of junction can be used for both through-roads and ones that terminate at the motorway/freeway, If you were to look on Google maps at a random junction on a major English motorway or dual carriageway, you'll find loads of this style of junction!
And a median u-turn basically requires you to go really slow, and even block other lanes if the's a big vehicle. So it's really not ideal. And Diverging diamond seems quite a bit more forgiving to busy traffic. I used to think roundabout interchange are great, but considering the space it take compared to DDI, there's no point. And if you encountered real busy traffic in a roundabout, you know that it's not all good. Sometimes the road is just busy, but the other side just get priority access and one side would wait for minutes for 2 or 3 cars to go in. That's why they add traffic lights. And that take away the good thing about roundabout.
Great stuff! It’s cool to see you getting back to some interchange videos with CS2. Those were the videos which first hooked me (on your channel, and on the great intersection tool mods for CS1). I’m currently experimenting with an idea where the highway which enters the city has multiple exits… kind of like a hydra with multiple heads, I break a 4-lane highway into four single-lane off ramps… and I send each one to a different spot… I’m also experimenting with divorcing the city-to-highway traffic infrastructure from the highway-to-city traffic infrastructure… I had the idea back in CS1, but never tried it… however I like the default road tool so much in CS2, I was inspired to give it a try.
City near me has the freeway offramps lead to one way roads through the downtown area. Different opposite direction one way roads provide the on ramps.
that last interchange exists in Middletown NY off of 17/I86 it makes use of the much larger lights at the edges with the U-Turns also a entrances to major shopping plazas/Mall. it also helps with restricted space as I86 is climbing up a cut in the large hill and added slip lanes could be problematic.
I think splitting the priority road into two one-way roads is better for an RCUT. It also ends up looking more like they do IRL. Where I'm from in Texas, they pretty much only use RCUTs when the traffic demands highway capacity from an arterial, but there isn't enough funds to build a full highway with interchanges. They're also called "Super Streets".
Hwy 74 leaving East out of Charlotte/Matthews, NC to Marshville, NC has a lot of these. A mixture of the R-Cuts, Michigan Lefts. No bow ties though They took a year+ a few years ago and added them all along to help. I’d love to see if they helped with accidents in the least. Also built a tolled bypass to try and alleviate congestion. It’s still a stupidly busy road. Enjoy taking a look at that one, lol
hi YUMBL. i just wanted to ask if could you try to make this intersection? it seems nice to build, the cordinates: 47.36813413362279, 19.118027607067916 if you can paste it into google maps, i dont know how precise it is in other apps. hope you make it! also i really like your videos, hope you will upload soon.
This reminds me of a thing I saw in Spain where the left turn is made by splitting off one lane, taking it off the road and into a left turn to make it into a 90 degrees crossing. It looks a bit like a roundabout but works completely different. like on this location: 42°09'32.9"N 0°19'35.6"E
I call these Colorado lefts, as when I lived in Denver and left turns at busy intersections in rush hour were a nightmare, I used to drive through the intersection and U-turn and come back and make a right. Beats waiting through 4 light cycles.
Wasn't that illegal? I grew up in Denver, and I thought u-turns were always illegal by default unless specifically stated at the intersection (of course, I could totally be misremembering my driver's handbook days--it was a looong time ago).
@@lyrrakell I made legal U-turns to the best of my recollection. I was active duty USAF then and pretty much a rule follower. However, any time it may have been something irregular I called it creative driving.
I've implemented the Michigan Left on a couplet+4-lane interchange, as well as a couplet/couplet interchange. It isn't working out very well. I really want TM:PE.... Thanks for the video. The bowtie is a possible solution for my Golden Gate bridge issue.... And yes, IT IS A MICHIGAN LEFT. :)
I have sort of seen the last interchange in the real world (harvey mitchell & raymond stotzer) but it was only temporary as the interchange was still under construction. Now its a diverging diamond exchange.
come back to me when I can customise traffic lights in CS2. and when traffic stops ignoring lane restrictions all the time. Good lord we're so hamstrung right now.
It's not updating. The spawned traffic finishes following their pre-determined route and the new spawns then follow the new rules. Updating traffic ai would be great but we got... What we got.
Exactly. Vehicles will then choose the updated path. I think the alternative would include thousands of agents recalculating at once which would cause a lag spike.
What irritates me is traffic cutting through on pedestrian roads to reach their destination even though it's not allowed. I hope a mod fixes that soon.
Nice one but personally, I just roundabout the hell out of my cities, lol. Seriously though, I cannot wait until modding is available again as the lane control has to be more manual to address many traffic issues that could be avoided. I have a 280+ pop city, and everything is going great, but no matter what, traffic flow never gets above 63%.
@YUMBL I get that, but u-turns are a nightmare for lorries, busses, etc. These are still signalised junctions, so traffic is still stopping. While a roundabout wouldn't prioritise thru movement on paper, it would likely lead to less stopping in practice.
On the last one ive never seen one like that there could be but there is the reversal of that where the on and off ramps have the u turn a MUD Michigan urban diamond
2:38 the knowledge of a p turn scars me two days in a row now alzo "Michigan left" im going to call it the Melbourne Right turn (Collingwood and Frankston are the 2 places with this in Melbourne(
Where in this list would something like the new jersey jughandle fit in? I need to play around with U turns more in CSII, my CSI prejudice makes me often ignore them.
Similar but different. It creates a second intersection that has cars crossing two directions of traffic. MUT lets drivers cross one direction at a time
@@YUMBL I’m stuck playing cities on console. I was actually just watching your small hiway connection video. Even though I’ve been playing for 5+ years, there’s so much to this game, that I find myself forgetting the little things. So I go through your videos trying to implement what I can to modless vanilla. I was trying to fix some traffic last night and remembered the old town policy. So searched your videos for it
Have something like this near me. Though it has a half moon round-about thing where the U-Turn is. (kinda like a bowtie but not really) It would work in theory, but people don't know how to drive so...
Do you have a visual reference or real world example? What I made allows the main road to go left right or straight at the intersection, the secondary road can only turn right, like a typical RCUT, if memory serves.
Can you provide a steam collection of realistic roads network that you use or good for alternate vanilla road in Cities Skylines 1? It would be nice to have!
@@YUMBLFunnily enough in the real world making a u-turn in a semi is usually grounds for immediate termination. Source: Am a long-haul trucker, and seeing this is really killing my immersion, lol.
I don't understand the point of an RCUT in _any_ circumstance... it does the same as a roundabout with more space, less capacity and a higher danger rating... why would you ever built it?
I must ask: Michiganders, does the Michigan left feel annoying to have to backtrack down the wrong way to turn? Or is it nicer to not wait at left turns?
You get used to whatever is in front of you... so, no, it's not annoying. Without left turns, there's greatly reduced accidents at intersections. We make up for that by being some of the most recklessly fast drivers in the Midwest.
it depends. Sometimes it is, when the traffic on the boulevard is heavy. Personally, I try to avoid taking routes that make me do the Michigan lefts if I can. It's an inconvenience for sure. Deconflicting intersections is a good thing though.
I travel along Telegraph Road in metro Detroit every day, which almost exclusively uses Michigan Lefts. The only annoying bit can be when right turns on red are prohibited. You then end up in a triple-tap of stops. Once when you get to the intersection before you can make your right, again at the U-turn (crossover is the other term used here), and then again when you are at the intersection again. If there is no prohibition on right turn on red, it can go a lot smoother. Last issue can be when traffic is heavy on the main road approaching a popular left turn intersection. There can be a backup through the intersection of traffic waiting to make the U-turn/crossover. Most Michigan Lefts also include a signal at the crossover, to allow protected U-turn traffic and reduces the volume of traffic waiting for opposing traffic to clear. These signals are timed with the main intersection to allow "nearly" free-flow of traffic.
I've never had any issues with backtracking. In my area, the lights are timed well enough that I rarely even have to stop. Especially since we can turn right on red, and the u-turn is often allowed on red if traffic is clear.
Is it just my city, but my sims never uturn on the roundabout I put on a 4 way intersection. I tried this "Michigan Left Turn" thing but my uturns are 4 way roundabouts on both sides, but they never do u turn there. Can anybody verify?
Is there a reason for them to U Turn? For instance if you use a non median road traffic can just access building on the opposite side of the road directly. No need to u turn.
7:14 this looks like it is the Telegraph Rd (US-24) and I-96 junction near Detroit, Mi, actually. only lefts are allowed in the real one, and it has a flyover for anyone just going straight through. it's really garbage. always backed up and just a bad design.
This reminds me of orange beach Alabama. The entire strip was a stroad but to limit traffic crossings you couldn't turn left in most places, there were just a ton of U turns everywhere. Kinda weird
All that does is add distance to their journeys. Can't really see how it's an improvement on traffic, in the game perhaps but I think that just goes to show they've made it wrong. Like we're all gonna mod the fk outta that system if that's how it stays and that makes no sense with cs2.. it's new so make it how most of us are going to play it.
I dont get Colossal, they are giving patches here and there but they cant imply this simple thing. Give us the option for dedicated lanes and customised traffic lights. Come on 😑
