- It's called a 'Continuous Flow Intersection.' I take a quick look at traffic signal engineering and how this new type of displaced left-turn improves traffic flow by 30 percent.

I came here to say “we have tons of these in Utah!”
And then you said it.
Same lol
This guy is a nerd...in the best way! Rob you rock man I’ve only seen 5 of your videos so far and I’m hooked these are so informative!
Same here!!
Then you should like NotJustBikes at least as much! : ruclips.net/video/knbVWXzL4-4/видео.html
Don't want to sound like a smartass, but wouldn't a large enough two lane roundabout do just fine? No phases at all, less electricity bills (only for street lamps, no traffic signals), less stopping so consequently less CO2 and less fuel consumption etc. Plus it allows pedestrians to cross safely, as roundabouts slow the flow, and that even rhymes, wow. Conclusion: roundabouts are awesome. Right?
@@inertboi yea.... you know building a round about cost millions right?
@@coltonkinsey2977 hell no, where did you get that from? They cost about as much as the conventional intersections to build, and are much cheaper in the long run. You're way off buddy.
Wow, never seen one of these before. You need A LOT of space for them.
You do, but it’s wonderful!
Better bulldoze that bicycle lane and bus lane to make room.
@@schroedingershat7912 and homes, stores, parks, etc?
@@josephj6521 Only if we replace the homes with high density housing with no parking. They don't need parks because they're in a 'high transit access area' (at least until we bulldoze the bus stop for another intersection).
Considering they're being replaced with on ramps and bridges, the space isn't really an issue. Either one takes plenty of land.
Dude your channel directly appeals to a weird nerdiness I have about traffic engineering and I'm so thankful I found it. I'm literally a doctor in training lmao.
Cities skyline will fix that itch
Where did you find a revolving McDonalds sign? Ain't seen one in years.
I've NEVER seen one!
The intersection shown here is University Pkwy and Sandhill Rd in Orem Utah. So there is at least one there.
There is one near my house on Dorchester Rd. Summerville, SC
Riiight
@@JonathanNelson-nelsonj3 The one at the beginning of the video in the time lapse was State Street and Center Street in Orem. So there's two, less than 2 miles apart.
I LOVE the CFI in Cities Skylines. The improvement over a conventional intersection is dramatic, and watching it work is like art. I didn't think I'd like it even better than the diverging diamond interchange, but I do. It is THE highest capacity level intersection, and so much less disruptive than a grade-separated highway interchange.
it is great for traffic flow, but the only problem I have with it is that it doesn't let through traffic continue without stopping.
@blackhole4106 At the levels of traffic where a CFI is needed, nothing short of a highway interchange does that. If a roundabout hits capacity, people have to stop and wait too.
The "long term" strategy to these is kind of clever in a way. In the example you gave they had already purchased the right of way for the planned future freeway, so maximizing that footprint without building a grade separated interchange increases the value of that investment while waiting to finish a future phase of development. Also the increased pre-existing road surface seems like it would make construction phasing safer and more efficient when you do upgrade eventually.
People can’t even handle a simple left turn arrow. I can see this going very wrong in Los Angeles.
Getting a driver's license is too easy in America. It should be a hard test where you must get all the questions right. A hard question could be the difference between a life saved.
@@ILovePancakes24 agreed
Miami too.
@@ILovePancakes24 should be a returning thing. Like you need to recertify every 2 years. Lots of people don’t seem to know the rules of the road
In Germany we have something called "Right-hand drive bid" [Rechtsfahrgebot] which applies especially to our Autobahn. (Highway) This rule ensures that overtaking is only legal from the left side and that slow vehicles have to take the lanes on the right side. I have seen a lot of dashcam footage with accidents that would have been prevented by this rule.
I go through this intersection a lot. It made a huge difference in how long it takes to get through that very busy intersection. I love the new design. Very smooth and efficient.
They added one of these to my hometown 2 years ago. No one had a clue what they were going for but it's honestly great.
Americans: "we have to find a way for people to turn left without many crashes... Let's make a Super intricate road!"
Europeans: "...what about roundabouts?"
That was literally my thought when starting this video 😂
Roundabouts in The States are really becoming fairly common.
They blew a lot of peoples minds at first, but they've adapted fairly rapidly.
I've experienced a few of the intersections in this video and they DO WORK.. but are much more intricate and people don't pay enough attention to be in the correct lane upon approach for them to be so sporadically placed.
In most areas of the US anything heavier than neighborhood traffic comes to a 3-way standstill in a roundabout and they greatly increase accidents because most US drivers aren't familiar with them
There's actually a roundabout just off camera to the left!
They're unfamiliar to most drivers in the US. The cameraman is standing in behind the largest university in Utah. Very few people know how to drive in them properly, and the traffic in the surrounding area is too heavy for proper enforcement (or teaching).
Two: roundabouts are often known as a traffic calming device, because they force traffic to slow down. This doesn't work well in places like Utah where snow plows require a certain amount of momentum to do their job properly.
@@osco4311 the whole slowing of traffic is crap doesn't stop the plows in northern Europe: Sweden Finland etc. That all have very snowy winters and require the road closing. Roundabouts literally would solve this issue and more
In the UK we wouldn’t even attempt to find a “one size fits all” solution. You just build whatever intersection suits the circumstances and people just deal with it. (Well mostly).
[shudders in magic roundabout]
hatched yellow boxes work really well
basically what these americans are trying and failing at
@@Hdtjdjbszh hatched boxes work when people actually listen to them... or know what they even are
Yes and because of the ''non standard'' aproach you have no idea what lanes you can use for forward unless you have clear markings and signage. Lack of road markings and random unnecessary logic are the reason for plenty of near misses and accidents that could simply be avoided by a bit more standardisation and leaving only the more complicated situations as ''exceptions''...
A big weird roundabout with 7 directions, 23 traffic lights and 3 shortcuts so nobody understands what's going on?
So glad I live in Utah where we are constantly changing the intersections and confusing everyone
mmm yes and annually seeing the state flower; the elusive orange cone.
And every time it rains it's a guessing game of whether you're following the right semi-invisible road lines
Without clear signage I would totally miss the left turn, because I would think "Oh, I'm not turning there, I'm turning up *here*!"
Thats the problem. Road signs in the US are not clear or consistent. European road signs are much clearer.
Excellent videos, Rob. Subscribed when i saw your first one.
The big drawback of cfi is the space it will take. In my opinion, when the space is tight and traffic is heavy, the best way is to have each direction have its time, with smart use of right- and left- turns in other directions so the use of common area is maximized.
There’s one of those on highway 71 in Austin! I just thought it was poor design but it makes sense. Thanks for the info!
Austin liberal commies using socialist engineering!
Jk 😋 we have a couple here in Georgetown Tx and boy it works! Kinda confusing but you get used to it 😁
There are also a couple in San Marcos and College Station.
We have one in baton rouge louisiana and i never knew what they were called until now. You would never know how good it is until you have one it helps traffic sooooooooooo much. The 50% of the time having green is pretty accurate the traffic flows so well.
Airline at Siegen, I live right around the corner. Greetings!
@@wadeguidry6675 hiya haha
I would love to see a video about the Michigan left turn.
I live in Canada and they are just about to open the first ever displaced left turn in the country in my hometown. I personally think it'll be a lot better than the conventional intersection however a lot of people are freaking out over it and saying they're going to just completely avoid it. Hopefully, once it opens, they see it's really not that hard to navigate and the only difference is the left turn.
We have several of these in Fenton, MO on Highway 30, and they _massively_ improve the traffic flow during rush hour. We also have multiple diverging diamond interchanges as well, but not nearly as many as Springfield, MO.
Maybe you can do a video on the complete lack of high mast lighting in CA and how every other states puts them on EVERY interchange! Cool videos BTW!
didn’t even know this was a thing until i left CA 😭
I've actually seen it over a number of interchanges and some high-traffic exits in the LA/OC area, especially near Disneyland. It seems to be spreading as they work on other areas, as well.
My favorite unique road intersection is where you can take an exit and then rejoin the express lanes at the the light and beat a line of cars.
Palatine Rd.
Doing this at a smaller, 2 lane scale also has its benefits. Especially for those making left and right turns. I just cant help but feel like its an optimal solution in almost all cases...
You can do a lot of interesting designs when you are in the country side where the land is almost free.
You also usually don’t have the traffic to justify weird designs.
Yeah there's really a lot of opportunity to ruin everything with more concrete
The intersection shown there isn't really in what'd I'd describe as "countryside" - it's right next to a university campus so the land was probably pretty expensive.
We got one of these at 1431 / I-35 in northern Austin. 1431 used to back up for a LONG ways every morning leading up to that interchange, now it goes as smooth as ever. Big boon to traffic in that area.
We have one of these in Lafayette La (Johnston St @ Guilbeau Rd). People still get confused at it years after
I saw someone turn left from Johnson and end up in the left turning lane on Camellia just this week.
I swear there’s on in Baton Rouge but I can’t find it
@@nc818 It was the first CFI in the US, and it's at Sherwood/Siegen and Airline.
I love this kind of stuff. I suppose I'm a traffic nerd like you. Didn't know there was so many people like me! I'm in Utah also and like the creative things they've done on left turns. You should do one on the U Turn lane things.
can you do a video on teardrop roundabouts/dumbbell roundabouts?
I'm not familiar with those. Holy cow, those look crazy! I need to see if there are any out west that I can see/video. Thanks!
@@RoadGuyRob look at carmel, indiana
Look kids Big Ben Parliament
These are super common at minor freeway interchange in New Zealand.
@@RoadGuyRob I-25 and 14th Street, Loveland, Colorado. Right next to the Loveland Park-n-Ride.
UT-154, also known as Bangerter Hwy was an under budget solution which saved cost without compromising performance more an necessary. In SLC County is also Redwood Rd. which also uses a CFI.
Or you could build a roundabout! They work no matter how busy they get
False
Happy Valley, AZ roundabouts were redesigned into a crazy looking intersection
Look it up if u don’t live here
Because they were way too damn busy
@@madmonkey8141 from what I find online the 2 roundabouts were always meant to be an interim measure. Looking at the aerial photos of them, they are quite small compared to the ones we use in the UK. In fact they are on par with the ones we use to get into a supermarket and don't look fit for purpose for a busy intersection.
Although I agree with you in principle with your particular example, a big 3 lane roundabout at the junction in the video would work better than the way it is currently. You could also use traffic lights on the roundabout during rush hour, again fairly common here.
@@anthonycarless1748 On Dutch way of roundabouts; ruclips.net/video/41XBzAOmmIU/видео.html
@@raphdroidt692 just like ours but without the cycle lane. Do the cyclists have right of way?
I’ve seen this in Mexico. And never understood it until now. I thought it was weird too. But now having an explanation as to the why. I get it. I love it. And I wish we had this in souther California.
HEY THAT’S MY SCHOOL YOOOOOO I’m like “wait, Utah’s university parkway uses that!!!”
I saw the name of this and I was like Ibet that is what they are using on university parkway. Then I started the video and was confirmed.
That intersection doesn't work well for me, there have been times where cars cross in a yellow light and get stuck in that intersection during a red light. My solution is to make a left turn a block before and go the long to get to that shopping center there, I have noticed that over time more cars doing the same thing, I got that idea from public transportation, the local bus does that.
Me too!
@@PurpleObscuration: "Shopping center..." Ha, you could just say "Walmart."
Brigham Young's ghost must have convinced them! 😂
There's one of these in downtown Toronto. When one wants to turn left from Lakeshore rd traveling East bound on to Bathurst st traveling North bound. They have a crosswalk at surface level and its staggered; you cross the right hand turning lanes going South and the left hand turning lanes going North and then you need to wait for a secondary crosswalk signal to walk across the East West traffic.They even have dedicated transit lanes including streetcar tracks. The intersection is enormous. I love turning left from the collecter lane. For this particular intersection I believe it's a permanent solution.
In London in the UK they had a craze for building flimsy flyovers out of girders in the 70s...
They were only supposed to be temporary solutions but they're still there today and amazing for traffic flow. Even just having one lane at 30mph crossing an interchange helps a ton with traffic flow on roundabouts (as this is the UK after all - but could definitely coexist with some American cross-section designs). Big examples in my mind are Gallows Corner, Lodge Avenue, and the Hogarth Roundabout
Great information. I travel to Logan Utah twice a year. On the way back to the Salt Lake airport, I drive through one of those weird left turn lanes to get on the freeway. I had no idea why it was designed that way. Now I know. It's actually pretty clever.
Thank you. Texas needs these so bad on hwy 380 between Denton and McKinney. Right now they are adding more lights on an already clogged and busy highway.
Feels like a good opportunity for someone to end up in a lane going the wrong way
Obviously the designers know that and design accordingly. Like how they place a jutting edge on a highway exit so people dont accidentally turn in.
I was just in Taylorsville with my girlfriend yesterday. Hadn't been there in a few years, and I forgot about this intersection by the Walmart and the high school. Almost turned right into oncoming traffic that was getting ready to turn onto Redwood Road. We both thought that was pretty weird, but then I remembered these are all over the place in the South SLC area. There's even one five minutes away from my house, on Bandera and 1604, just outside Helotes.
Oh your God, Wisconsin is still trying to master the round about. Couldn't imagine having this.
Illinois too, I'm in Northern Illinois about 10 minutes from the Wisconsin border and they're putting them in over here too. They are built in areas that honestly didn't need them and the budgets are in the millions, its insane.
@@AcousticGString yep, seen unnecessary round abouts. Some I'm told are only busy part of the day such as a school or large company letting out. Cities will put in small round abouts to discourage semi traffic in certain areas.
Oshkosh wi has round abouts back to back. No sooner are you through one, there's another. You really need to know where you're going when you hit these.
My pet peeve with round abouts, beside snowplowing, is that they mound up the center and plants things obstructing the view of traffic. The whole idea is to increase traffic flow instead they hinder it by restricting the view.
Some other ideas: ruclips.net/video/41XBzAOmmIU/видео.html
As someone living in the US who is from a country where roundabouts are common. Yes people struggle with them here. Just think of them as joining a one way road, that's it, you get on it when it's clear then take whatever exit you need. Don't stop on it just like you wouldn't randomly stop on a normal road because someone was waiting to pull on to it. Also it keeps traffic flowing and doesn't need electricity. It could be used to replace so many stop lights. It really would be a great solution for a lot of intersections. You can use them to pull a u-turn safely. I love them.
Round abouts are pretty awesome when done correctly and not confused with a traffic circle.
Hi Rob,
I have never seen one of these CFI. In StLouis we have a few diverging diamond, but not that popular. In Detroit, they have jughandle left turn lanes. If you want to turn left, you turn right, go 100 feet or so, and get to the far left lane and make a U-turn. Some have a stoplight to regulate the flow. Seems to work well.
South American cities with broad boulevards work like that… Wanna turn, any direction, leave the main road to a side road and then make turns, left or right from there… The “Óvalo” traffic circle is also popular, often incorporating an underpass for the major road… Lots of fun to drive in South America!!
I've driven this exact left turn so many times to go to Walmart and there's a couple on Bangerter, and I like them
Hey Rob, What about the famed Michigan Left?
We had one of these built in my city not too long ago. Its confusing to use at first but after using it a few times it makes a lot of sense and helps with the flow of traffic.
I might not stick to the channel, but its not because of Rob. This guys enthusiasm and general love of what he does is infectious, I hope I find something I love as much as he seems to love traffic engineering.
It would had been easily solved with a roundabout...
I was thinking that too. But Americans aren't well constitutionally suited to big roundabouts. Each driver thinks the whole thing is theirs. Drivers in roundabouts have to be willing to work together.
My hometown of Evansville just announced they’ll be adding a bunch of these to our main “expressway” road through town. I think these are useful for areas than don’t have the space/money/don’t want to hurt businesses by building a whole highway.
That is ingenious - basically you are allowing the cars that want to turn left crossover the oncoming lane while the side street has a green.
Now for the next video: The 2009 MUTCD created a new "Flashing Yellow Arrow (FYA) which allows for people to make left turns even though the oncoming lane has a green. In old days, there were signs "Left Turn Yield on (Green Ball)", but these new flashing left arrows bring some additional control to that idea. They've been popping up in my state in the past few years, and they took a little getting used to. Would love to see a video about them.
Try a traffic circle. It’s much more efficient. But then again most motorists aren’t smart enough to use them correctly.
Idaho have been putting CFIs in Boise. And replacing old Freeway interchanges with a SPUI. or Single point Urban Interchange.
In Seattle there is an intersection near the university where pedestrians cross down the center of traffic. Then in the New Jersey area you must turn right to go left; they have hidden Clover leafs everywhere.
utah is literally the wild wild west of roads. i come from norther cali and the roads are extremely basic here (my city of 300k has 1 roundabout that i know of, to put that in perspective) and i know we were following the rules but it felt like we broke many moral and spiritual laws driving in salt lake city 😭
As someone who uses an intersection like this quite often, I find them awful. They take FOREVER and people just don't know how to use them
Do you know why they are confused? Que up at the arrow of your direction sounds pretty straight forward to me.
@@p1x3lman you underestimate how retarded some drivers are
Why the heck am I watching videos about traffic design? I found your videos the other day. They're so damned entertaining. Rob could probably make paint-drying videos fun to watch.
As a European, just build a damn roundabout 😂
Problems: 1. We're actually _not_ European, and 2. that would probably be too expensive for this size of street and our state, or too much hassle to go around in right there on our way to the freeway which is just barely past that.
@@HelloKittyFanMan. Yes, we know you're not European, because you drive cars big enough to have a grizzly bear behind the steering wheel. Point is, a roundabout or turbo roundabout is definitely cheaper than some convoluted traffic light system. It depends, of course, on how many lanes of traffic you have, but more than two lanes in either direction should not have a single-level intersection.
@@SeverityOne: Why do you bring up the size of _some_ of our vehicles, as if that should make any difference (like you don't have any over there)?
And what do you mean by "a roundabout or a turbo roundabout," as if turbo roundabouts aren't already roundabouts despite the word "roundabout" in their term?
Look at the number of lanes on our road right here in the video then. It was my understanding that a roundabout that size could be prohibitively expensive, at least for our city or state. And many more people head to the freeway from this side than from the west side of the city, so they probably are glad that they don't have to be bothered with hooking into and out of a big circle every time they just want to go to the freeway entrances, which are just the next block.
@@HelloKittyFanMan. I didn't say "as a European", that was "nerdegem". And indeed, nobody over here drives such big cars as they do in North America. The roads simply aren't big enough.
A turbo roundabout is indeed a roundabout, but a more efficient one. It has a greater capacity than a normal roundabout, but like a roundabout, it has a certain limit to its capacity.
Point is, a roundabout (and especially a turbo roundabout) has a greater capacity than a traditional intersection, with or without traffic lights.
I've never quite understood the American aversion to roundabouts. They weren't a thing when I was young (let's say the 1970s, early 1980s) but now you find them everywhere. The other Europeans looked at what the British were doing and figured "yeah, that makes sense".
@@SeverityOne: Oops, I lost track of which people were saying what, LOL; sorry! Anyway... I bet there are some people over there at least some places in your continent with things like a Ford Excursion or a Chevy Suburban. Maybe not many, though.
You're still not making sense with your " 'turbo roundabout' vs. 'roundabout' " logic. It's as if you don't think the differentiation words "standard" and "regular" don't exist, so you say "but like a roundabout" as if the other option wasn't also one. You did use the word "normal," though; however, you didn't perpetuate that. The comparison only makes sense if you continue to use a word like that to separate the two.
Roundabouts "weren't a thing" when you were young? Oh? When were they invented, according to you? The encyclopedia says the term was coined in 1960 and the first standardized one in the UK was installed in 1966. And maybe they existed even before the 60s under a different term, but I can't find anything "concrete" until 1960. So obviously they existed before you were born.
I don't know about the Latin countries or Canada, but at least here in the U.S. part of the continents, I'm not sure why people claim we've had an "aversion" to roundabouts. We have several smaller ones right here in Utah. Maybe on this particular road they've studied that and figured that it wouldn't clear enough traffic like this CFI does. Maybe we don't want to have to go through a roundabout right before trying to enter the freeway right there. Maybe it would be too close to the roundabout that's already at the front of the college right there. Maybe they figured that it would be too costly to figure out how to integrate and then do so with the proximity of this intersection's branches combined with the number of lanes (it may be too irregular). But that's just my guess for this particular one. I have no idea about the others. But we do have a lot of roundabouts these days. Even my parents' little city of around 3000 people installed one at kind of the front of the city from the outskirt roads. It's a single-lane one as most of our roundabouts are. I don't even know if we have any multilane ones.
There is a traffic light at the highway that goes past my home town. There have been so many accidents there and people were lobbying for YEARS to put in a turn signal but they said that the intersection wasn't "Busy Enough"
But the problem is if you're in the turning lane turning west the road across from you skews slightly to your right... so if theres a large pick up truck or semi across from you trying to turn East you absolutely CANNOT see oncoming traffic.
They finally added a turning light this past year. People REJOICED.
I'd rather sit an extra minute or two than endure 10 years of road construction to add these lanes.
I think these are the best alternative to roundabouts at major intersections that exists. I'll admit, I'm also a bit of a nerd with traffic control because of my life-long love of games like Sim City and Cities Skylines. The thing the CFI needs is the same thing roundabouts need (even still,) and that's public education. A CFI can even be used on a smaller scale with one divergent lane in tighter areas to prevent the need to add lanes to the whole street. It's very clever and works very well when the lights are timed properly.
We used to have something very similar to this at a major intersection in my town. It had been put into place in the 1960s. For some reason, in about 2009 or so, the State of Michigan removed it and put in a standard intersection with a two-phase traffic signal and no protected lefts. It was a bit strange, but everyone in town was used to it. It was the only one I ever encountered.
I live in rural Utah. Everytime I go to Salt lake and get in one of the intersections, IT DRIVES ME CRAZY!!!
Woo Utah! I love these intersections. They feel so much faster. Especially on redwood and 5600
Awesome continuous-flow exposé. Cheers!
your videos give me comfort during work or travel
Thats all fine and dandy, as long as all the left turn traffic fits in that left turn pocket, but many times in my state, traffic backs up for MILES, and the left turn traffic backs up into the straight lanes.
Thanks, Road Guy Rob.
It's amazing how these things that make walking even worse are considered a band-aid to the final solution of just ridding the area of foot traffic entirely, when all you did was make the area into a pass-through nothing blob space that's ugly, noisy, and produces no tax revenue. Good luck with that.
There's suprisingly a lot of this in Jakarta, but lot of people jaywalk and doesn't fear crossing the road so we don't make expensive tunnels (no space anyway), we make bridges if necessary or just slap the zebra cross (sometimes)
They put one in here at Colorado Springs it a busy intersection where they couldn’t put a bridge about a year ago. I was initially opposed to it and thought it was weird would cause months of accidents, it’s actually worked out very nicely and most people now like it.
Yeah, at Woodmen and Union. I like it, but it does have one flaw. I’ve seen repeated occasions where someone turning left in the outside turn lane from northbound Union to westbound Woodmen ends up taking it wide and enters the turn lane for traffic turning from eastbound Woodmen to northbound Union instead of the lane they’re supposed to use. It’s particularly bad if someone who does that makes that turn as their light turns red. They end up going the wrong way down the turn lane just as the traffic turning north on Union is coming and they have nowhere to go because they’re blocked in. I’ve seen a couple accidents there because of that.
Other than that, I think it’s a very efficient intersection.
I swear, this guy looks like PewDiePie's half brother!
Pennsylvania got its first diverging diamond at the Interstate 70/U.S. Route 19 interchange in Washington County
I did not know about that. I am sure to be there for some odd reason sometime in 2021. I live off of i79 near Neville island. Edit: I watched the video about the road. Now that I see the design, I may not. I would more likely be passing through I70.
ah, yes... the youtube algorithm, brings us here once again
I love the alternative intersection. There are a couple in Indiana. At least one in Fort Wayne. I love this intersection.
Now show us how an elderly wheelchair user and a kid biking to school get through here.
Did you not watch the video? There is a pedestrian tunnel beneath.
Damn I watched couple of vids, this channel is truly a hidden gem which for sure deserves M of subs! Thanks for those great vids!
Awesome. I drove Bangerter highway and was only slightly confused lol.
We have one of these in Austin. US 290 @ William Cannon Drive. I don't frequent this area but the few times I've did I have come across this design. Also we have a diverging diamond interchange in Round Rock. I-35 @ RM 1431. We also have roundabouts. Of course the traditional 4-way intersection gives us 4 different types of intersections. A lot of information to process when navigating these roads.
I like what I saw in New Orleans. On the main roads you can't do a left turn, but they put U-turn areas in the middle of the block, so you go past your street, make a quick U turn, and then a right at your street.
I believe we have one in San Antonio, TX which meets this description and it is at an intersection of a thoroughfare and a freeway with offramps. For when the freeway with offramps still can't handle off the traffic.
I love the content, only problem is that I binged through it all already and want more lol. Looking forward to more great videos.
119th street in kansas has a like, mile long off ramp. South bound 435 traffic has to merge through this off ramp that backs up into 435 during rush hour. They're making the 119th street interchange a CFI to deal with the massive amount of traffic.
dude Bangerter Highway is the only highway I remember from when I grew up in Utah. and it hit my nostalgia vein when you said it.
This is such a niche and cool channel. Great video.
There's one in Round Rock, Texas. It was a bit weird at first but one gets used to it. Yes, it does work and very well at that. It used to take 3-4 light cycles to make it through the intersection and now it takes no more than 2 on the busiest day. I hope that transportation folks convert more intersections to this design.
We have one of these intersections in our city. It's been life changing
Locally, in Chattanooga, Tennessee Department of Transportation has been working on re-engineering I-75 and are creating similar ideas. The 75/24 Split recently got a new Over Under design which is slicing the southbound congestion significantly and giving a fair fix to the north and west bound traffic. On the same split, they're planning a bypass of Chattanooga and I think it's going to connect with the Cherokee Highway in Cleveland (approximately 24 Miles from the split) which ends into an Overpass on the Cleveland Bypass. If not that, then it's likely going to be suspended approximately 100 or so feet above the main I-75 and continue alongside it with exits at Shallowford Road(Exit#5), Old Lee Highway(Exit#7) and come back down at exit 11 in Ooltewah. Going west, however, I have no clue and can't even begin to imagine what they're gonna do. They have the whole of Missionary Ridge blocking them. In regards to traffic management, however, we've been seeing redevelopments of Lee Highway and Apison Pike, primarily leading from the intersection of Volkswagen Drive, and Lee Highway out into Apison Tennessee. As more and more people move to Chattanooga and the surrounding area, more and more highway development is bring produced by TDOT. In Collegedale, on Apison Pike from Four Corners to a yet unknown end, they have been widening it to Five Lanes and plan to bypass the Railroad Crossing altogether and create a suspended highway, redirecting Apison Pike to a higher elevation. I believe this to be partially because of the McKee Bakery having problems getting loads into and out of Collegedale. Back to I-75. With major improvements to I-75 going into Tennessee, GDOT is trying to catch up by widening and adding bits to Georgia I-75 between Dalton and Cloud Springs Road. Back to basic roads. Although we don't have one of these yet, with our city being voted one of the worst nationally in terms of traffic, I'm almost positive our City Council has looked into using these and may already have plans to do so entering Downtown as well as in surrounding East Ridge and Red Bank. To be completely honest, I'm stoked to see the finished product. Of course, they started all of this back in 2010 and I'm sure it won't be finished until somewhere in the 2030's. But still, I anticipate these improvements will be a major player in traffic management and I will no longer have to worry about morning or evening rush hour traffic as much.
You should go over what to do when traffic signals are plugged with snow? There is a good solution so the don’t get plugged up. Great video by the way.
Haven’t seen one of those yet. Interesting idea. I live less than a 1/4 min from one of the few diverging diamonds in the US, and perhaps the first in Texas. Thought it odd at first, but it’s great. Have only seen or heard of a few accidents there in the past 4 years. There have certainly been more that I’m aware of, but it definitely seems there are fewer than at the more traditional intersections nearby.
Saw the first one being built here in SC last week. Cool idea
I gotta tell ya, you really do make this mundane stuff interesting!
It's nice that your state continually improves, whereas my state of Ohio is still stuck in the 1960s
I noticed more than one odd intersection in CDMX, but hadn't thought about them as possibly designed that way prior to watching this video.
Loving your videos dude. Are your sun glasses safety glasses from the hardware store? They look look mine.
They have this in Virginia. One is in Zion’s Crossroads, Virginia at I-64 ramps and the other one which is much bigger is in Norfolk, VA at the intersection of N. Military Hwy and Princess Anne Rd.
They have one of these in Snellville Georgia of all places and I never knew what the hell it was until this video. Works halfway decently but kinda makes a mess of what could’ve been a cute historic downtown
coming into it, I really had no idea what this vid was about, but it was recommended by RUclips. I saw "CFI", and I thought it had something to do with Certified Flight Instructors. As you can imagine, one of my interests is aviation. But it turned out to be really interesting for me anyways.
What a great and simple idea ... We should have these in England
Oh cool, you're right here in Utah, mostly featuring our CFI here in Orem, right by my alma mater! Yeah, I'm very familiar with that one, except that since I live in Hearthwood up by 8th North, it's faster for me to just use the freeway to get to that Walmart. Actually, I often just go to the Lindon Walmart because it's a little closer.
I've never seen this before. I can't say I'd be a fan.
There is one of these in Round Rock TX and every time I go through it I get a bit thrown off by it. I usually try to avoid that intersection - so there is some reduced traffic right there! I can imagine senior drivers would even have a problem with them as they pretty much feel wrong based on decades of driving normal roads.
Actually in MN at I35 and Hwy 97 south of Forest Lake, they built one of these INTO a freeway overpass, and it was weird the first couple times I drove across it, NOW, I am like Hell Yeah, let's do this... If you have a Trailer behind a vehicle, especially a lower powered vehicle (I don't have a $70K 500hp 1000lb-ft Diesel pickup) it makes left turns a LOT less nerve wracking....Even if you have a "Green Arrow" you feel like your "ass is hanging out" when it's trying to turn yellow as you're accelerating and shifting gears... With the CFI you just take your time and get going. - I don't know...maybe it's that Flip-Flopped thing Rob is talking about in his other video...it works!
