Graniterock is proud to lead the charge in revolutionizing California's transportation infrastructure with the construction of the state's first turbo roundabout, constructed in San Benito County at the critical intersection of Highways 25 and 156.
What's a turbo roundabout?
It’s not your average traffic circle! Designed for maximum efficiency and safety, this traffic solution combines the benefits of a traditional roundabout with enhanced features tailored for high-volume intersections.
By incorporating advanced design elements such as raised splitter islands, dedicated lanes and geometric improvements, the turbo roundabout promises a smoother, more intuitive driving experience for all motorists.
Best of all, safety is at the forefront of this project.
At the intersection of Highways 25 and 156, where traffic volumes can be heavy and accidents had been common, the turbo roundabout represents a major safety enhancement. With its reduced conflict points, controlled vehicle speeds and clear signage, drivers can navigate with confidence, significantly reducing the risk of collisions and improving overall road safety.
So, buckle up and get ready to experience the future of transportation as we pave the way for safer, more efficient travel on California highways.
I grew up in Hollister. That intersection was a very dangerous intersection. That's the best thing you guys could have done with the traffic in that Intersection.
UA-cam algorithm works in mysterious ways. This design is somewhat hated here (the netherlands, utrecht region) ever since it was first introduced over a decade ago, but the data doesn't lie, it's by far the most efficient and safest way to have a 4 intersection!
The biggest problem is people confuse YEILD signs for STOP signs
@@chrisl3540 I've been through the one in Hollister 3 times and a lot of people just stop and...that's it. They just stop there. I think they're waiting for their mommy to come get them.
Nine accidents in my life time. Three in traffic circles because they are impossible to figure out. None my fault and caused by multi lane circles where people changed lanes in the circle. I will drive five miles out of my way to avoid these. I'll drive through neighborhoods to avoid them too.
Think roundabouts are going to have to become a part of drivers ed
From the UK, and in Europe, roundabouts are just a way of life. But that is the first ‘turbo’ roundabout design I’ve seen. It will be interesting to see how it survives.
Europe has had these for decades and the resistance in the US is finally being chipped away. Bravo!🎉
european here. roundabouts should not be used in conjunction with highways or outside urban areas. all they do is impede traffic, which is then aggravated by people not knowing how to drive through them
@@StanleyKubick1 Interesting as that was really the opposite of what this video was promoting. FYI I know this intersection quite well.
We've always had roundabouts but not implemented in the scale of European countries.
@@MrXyzasdf This is the first turbo roundabout in CA.
There were quite a few traffic circles in NJ when I first moved there. And traffic would back up for miles around them. Most of them have been replaced with overpasses. Now driving through those areas is a breeze. Problem here in the States is people do not know or don’t care to know they are supposed to YIELD TO TRAFFIC IN THE CIRCLE. Most circles have signs that say exactly that. Overcoming that self importance and disregard for everyone else would probably reduce most accidents and fatalities.
If you look at the most effective turbo roundabouts in Europe they generally have a center Island about 20 to 30% wider than any Inlet Road. Sometimes even whiter than that. This one in Hollister you see the center Islands only about as wide as any Inlet Road. That suggests the radius is probably a bit too tight. Given the recent report of the nearly tripling of accident incidents through this intersection since the opening of the roundabout, it does hand towards possible design problems. Fortunately though those incidents have been much less severe than the prior intersection. So that aspect of the roundabout is proving itself. It's just a shame they didn't get a little more land to build it to a proper size for the speed of traffic in the area and the accommodation of semi trucks to accelerate properly through
yes, the entrance to the roundabout for the left turn lane seems difficult for trucks, especially American trucks.
_"Sometimes even whiter than that."_ Why do you have to bring race into this? 😂
@@grondhero lol, I'm leaving it
Tripling accidents?! That's really bad. I expected as much though when I saw you the jumps you have to make from the leftmost lane.
Caltrans is stupid. They still don’t know how to design intersections properly when given an optimized design
Studies have shown that a Roundabout reduced fatal crashes (drivers running Red Lights), but increased property damage crashes (lower speeds).
But drivers still don't know who has the Right of Way in a Roundabout.
Roundabouts containing more than 1 lane aren't intuitive. I prefer them to stop signs and they are definitely better at moving traffic, but they're just not intuitive. It doesn't help that they're not common in the US, so many people who encounter these for the first time are just going to look for a gap in all 3 lanes and stumble their way through, which works, even if they end up breaking certain rules.
As they become more prevalent I’d expect people will learn and understand. Right of way should always be to those in the circle. The give way triangles on entry should make that clear, but apparently some more education is needed.
Americans don't know how to drive.
Blame CA DMV and driving instructors for being unable to instruct and test for competency. It's not rocket surgery--if Brits can do this how hard can it be?
@@r2dad282. 😂 British people!
I’ve driven and rode my MC through this intersection more times than I can count.
This will save lives and also will keep traffic moving.
Fantastic design, very very well constructed, only problem is some are too ignorant to know what a yield sign is because American license requirements are so bad, otherwise much safer, faster and way more throughput.
We have lots of these in the Netherlands. They're safe, fast and cheap. This one looks good btw.
The angle for getting on the roundabout is a bit steep; could be slightly more rounded. Otherwise, 100% good. For reference, here's a nice one - www.google.com/maps/@51.5762479,5.1443638,98m/data=!3m1!1e3?entry=ttu .
Yup this was pretty much inspired by the trial ones in Netherlands. Hopefully we can have more roundabouts in the US. We are so used to stop signs and intersections it has been hard for people to accept roundabout let alone the unique turbo design but this is very intuitive and a step in the right direction.
@@portcybertryx222 Yeah, drives me up the freaking wall to be approaching a completely empty roundabout, with no oncoming traffic, and the idiot in the car ahead comes to a complete stop .... (banging forehead on steering wheel)
@@portcybertryx222 Being used to the turbo roundabouts over here, seeing a four-way stop in the US feels so incredibly backwards. It's like driving back into the 1950s with traffic solutions designed for very little traffic.
Nothing in California is cheap.
And yet ironically at 0:59 they show traffic doing the wrong thing and *stopping* in the middle of the roundabout. Granted they really had no choice as 2 large vehicles pulled out in front of them when they shouldn't have (especially the second one pulling the trailer).
If a semi is entering its going to possibly slow/stall traffic in the roundabout. There is no possible way to avoid that. They take awhile to get going from a stop.
@@dinkleberg93 And it's impossible for a pickup truck towing stuff to not go as soon as possible because their genitals would shrivel up and fall off.
The red car at 2:07 also doesn't stay its own lane, almost cutting off the SUV. And that's the example they use to show traffic moving smoothly. Hmm. Roundabouts are easy but there are rules...
@@FrietjeOorlog nobody follows rules here!
@@FrietjeOorlog but that isn't the fault of the roundabout, that's just bad driving because in the US you get your driver's license in the cereal box.
Amazes me how they can be so thrilled about the concept of a roundabout 😂
until they add ~12 to a town with 15k pop :D
@@illudedCeption still cheaper then a light intersection when you consider the cost of people being killed or taken out of the workforce due to crashes
@@trentr9762 you missed the point but yeah :D
@@illudedCeption your point was expense no? im saying its cheaper to build roundabouts :)
@@trentr9762 my point was that if theres 6 of them in a row with max of 1km seperateing them, it gets annoying as fuck and starts to get on the tires too
All roundabouts have three types of people using them. Those who have skills, those who make mistakes and cammers with 'horns' !
I dedicate this roundabout to my orange cat Turbo. RIP buddy. ❤
I went through this thing for the first time a few days ago. It's pretty different from other roundabouts I go through all the time, and seemed superficially confusing as I approached, but worked fine even though I wasn't in the best lane for where I was headed. The signage was clear enough that the lane I was in would work, and it did. After a couple trips it will seem totally clear. Tentative thumbs up. I don't recall if there were speed limit signs to slow people down as they approached, but if not, that should be an upgrade.
speed limit signs have to be installed from the state's DOT and not the construction company. So I am, sure they will get to it
That's actually a really intriguing idea. In Australia, we have plenty of roundabouts, but what often slows them down is people making the mistake of assuming all traffic to their right has right of way. It would be interesting to see if this modification to the design might improve driver behaviour, to not only make major intersections safer, but to also improve throughput.
It’s a Dutch concept that’s been long implemented there. Other countries are now copying it.
@@miles5600 en.wikipedia.org/wiki/Roundabout
I dont honestly see the benefit over a normal multilane roundabout...
@@aenguswright7336 Less lane changing and weaving.
That's true but given the average level of driver skills do you really want to take the chance pulling out infront of an incoming high speed driver from your right? I have little faith.
1:40 "... traffic on the left has the right of way..." I learned this many years ago while on a driving trip in the UK. It's so counter-intuitive. But it works and it makes sense. If not, you can get trapped in an inner lane. It almost happened to me near Seattle; I had to force my way out. Not a proud moment because I don't otherwise drive like that. The biggest problem with roundabouts is lack of driver education. Far too many people just do not understand how to enter, drive, and exit.
They should add that as a sign
"It's so counter-intuitive." I actually had to read that twice to figure out what's counter intuitive about it 😂You'll get used to it and over time your intuition will change.
Turbo roundabouts (a dutch invention) is just a more explicit multi lane roundabout : forcing you to choose the appropriate lane before entering.
Right turn shortcut lane tend to exist also on normal roundabouts.
It's a bit different, in that with a normal european roundabout turning left (or right in the UK) you hug the island until you exit, instead of spiralling out like a corkscrew. Specifically I'm talking about the non-painted ones, which are still considered multi-lane, unless it's physically impossible to fit two cars side by side.
Lived in Monterey over a decade and frequently had to go over Pacheco Pass to Merced on weekends. I despised that intersection on a Friday evening, especially in the summer. This has to be an improvement.
I had a car crash in this roundabout, the lady who hit us did not know how to drive in a roundabout, especially a turbo roundabout extremely confusing for her. Note that the roundabout was still under construction when this happened.
Americans should really learn how to drive and roundabouts
P.S. roundabout are good, but this one is quite scary because people don’t see the signs and panic and change lanes in the roundabout, people don’t give right of way, giant truck cut us off yesterday. P.P.S. People don’t know that you have to give right of way to people in roundabout
How come it's confusing? English isn't my first language but I can understand it right away.
Left lane can go left or straight, middle lane can go straight or right, right land go right only... how complicate is that???
American DMVs need be more strict and renewing should require passing the latest driving exam. My exam in florida consisted of a three point turn and parking in a mall parking lot.
@@Distress. That actually a huge point. People always talk about dutch infrastructure all the time, but that really is only part of the story. On average people need 43 hours of lessons with an instructor before passing their driving exams. Around 50% of people actually fail their first exam. So before you get a license you've been going through a roundabout probably hundreds of times and you've been told if you got it wrong, overlooked something etc. Good infrastructure helps, but good driver education probably is just as important.
@@Distress. Be the politician who screams that out in public, and you will find yourself unemployed fast.
@@engrishsheep It is complicated because the driver is already turning inside the roundabout, and if they get confused and enter the wrong lane inside it, any attempt to correct the mistake runs the risk of a crash. American drivers do not like a solution to be more complicated than the problem it was supposed to solve, DMV tests be damned. Sorry, but the 4 way stop while imperfect, is still simpler by comparison.
I’m up here in Oregon, and I think it works great! It’s a heck of a lot quicker than waiting at a light or even worse, fighting with stupid stop signs!
The sidewalk that goes around the middle part of the roundabout is for the tires of a semi trailer to use. Most truck drivers don't know that, especially today.
The under sizing of a “traffic circle” in a high traffic intersection will have a cascade effect. As with too many others, this is not large enough to properly accommodate large trucks getting into the circle before approaching traffic overtakes them and has to slow down. Once that happens, the ultimate result is the slowing of all the vehicles then inside the circle. This grouping of the in- circle vehicles automatically decreases the ability of entering traffic to find an access point thus making the possibility of rear end collisions more likely. 😐
It would appear that you would have to change lanes inside the roundabout if you wanted to do a 180 degree turn. It looks like that is allowable where the dashed lines are.
I’m impressed by a few things:
Deflection for the main movements is nearly head on. This should increase yielding to all lanes on entry.
Markings on the road itself. This is common in the UK and elsewhere but not so much in the USA.
Sharks teeth everywhere.
These should all be a given but it’s great to see them here and I hope they become best practice. I have thought for some time that turbo roundabouts would be a better solution that multilane circular roundabouts and have hoped that Caltrans would get to one before long.
It looks to be working well, here in England those that think they know best have started putting traffic lights in roundabouts, to me that defeats the purpose of trying to keep traffic flowing.
It's ridiculous when they do that because the yield markings clearly indicate who yields to who. Here, always yield to the vehicles coming from the left.
heck yeah! more of these in CA please!
Roundabouts are super popular in Europe! Glad to see that we’re finally embracing them in the US!
Some hate em, I LOVE THEM !! Best things ever, flow NO STOPPING, no electricity, no lights... simple.. easy USEFUL !! Put them in everywhere !! GET RID OF THE LIGHTS AND STOPS..
A really good design. Well done.
I'm happy with the adoption of roundabouts in our country/state. The thing we absolutely need to see next is the adoption of protected intersection design. There have been a small handful of protected intersections constructed in California in the past decade. It's especially important for collector and arterial road intersections in urban and rural settings (where bicycle connectivity is advantageous between adjacent villages and farms). The design principles can be easily applied to roundabouts as well. American traffic engineers have struggled immensely with designing safe road intersections for decades, so I can't understate the importance of education and awareness about the highly refined Dutch style protected intersection design, and its widespread application.
Good luck getting people to pay attention and read the sign
Good luck also getting the country out of trillions of debt but I digress.
was in rural Wisconsin last summer (Door county) and ran into a bunch of new small roundabouts on a US highway. First time seeing that in the US. I hope the trend continues
This seems like the perfect place for people to have takeovers/side shows.
2:16 oooof, how long until someone makes a left turn from the left lane because of those road markings?
Damn, you're right... somebody's gonna see that and try to turn left. 🙄
Caltrans needs to make the solid circle in those lane markings larger. That would solve the problem.
@@Milesco That could just be one arrow pointing forward as well. Then have an arrow at the possible exit.
Pick your lane early, stick to it and yield to traffic from the left, that's all you need to know, it's not a driving exam, it's just a roundabout.
I"ve seen people actually go the wrong way around a roundabout. It does happen although rarely.
@@SimonsRandomRantsAnd people get on a freeway in the wrong direction.
Much better than the typical British roundabout which have become hotspots for accidents due to people changing lanes or going in the wrong lane entirely which this roundabout prevents.
No that's just people's driving standard dropping. You are still supposed to enter a roundabout in the correct lane in the UK.
@@simonbrown7455 This is better than the UK, better lane markings.
@@simonbrown7455 While better training might help, typical British roundabouts are badly designed and actually encourage people to drift over lanes and go too fast.
for better roundabout you need... land
i watched the feed on this one for a few minutes, and it did not stop people from changing lanes lol
More of these please! Dramatically better design.
This is a good design, especially for people who are unaccustomed to the roundabout!
better: images.app.goo.gl/7vdPakeFF7rK
Great job guys! Looks like it's working great!
A few decades ago I live in Europe and call my local roundabout Turbo but for another reason. Fiat x19 1.5 turbo (after Market). 3am and some sideways fun.
This works great for those familiar with it and use it every day. Problem is when a driver who has never encountered this type of multi lane roundabout enters and gets confused then just stops 🛑
Sorry, but the signage is so good that anyone should be able to manage this type of roundabout, even without much experience. And those who don't are just really bad drivers and become dangerous road users.
@@gerhardma4297the worst drivers need to be removed from behind the wheel. This really does illustrate the need for better driver training.
We have many in Canada but smaller. It's always a treat when some A hole speeds towards it just to get right of way.
We call it “ The Circle “ in Long Beach, Ca. PCH, Los Coyotes Diagonal and Lakewood Blvd.
Been there forever.
Would like to see how this roundabout performs with truck and trailer 18 wheelers making a left.
you can watch the feed; lots of trucks going through. i see a lot of the trucks actually go when not clear and block traffic to enter roundabout (but not dangerously), but most can navigate the curves without a problem
It's not a good design for truck drivers. It takes too long to get a heavy truck up to speed causing slowdowns for the whole circle. This intersection is so incredibly busy that it's nearly impossible to find a spot to pull into traffic without causing them to slow down. I was through this intersection twice last week with my truck; scary experience.
Good luck. Been waiting 10 years for people in my area to figure out how to drive through single-lane ones.
I like the one lane roundabouts. Multiple lane roundabouts I end up being in the wrong lane and having to cut over suddenly. Might be ok if you drive the same route every day, but if you're routinely in different areas following GPS, more difficulty will be had.
This design illustrates each direction you may want to go very clearly. It would be prudent for drivers to familiarize with the concept of a turbo roundabout, and how to use it. It's also important to plan the route ahead of time, making note of the road layout and understanding any necessary lane changes before you get there. And most importantly, it's okay to make a mistake and end up going a different direction than you intended, just find a way back in the direction you need to go once you've made the mistake. Do not make drastic lane changes last second on the road or highway. I see it all the time and it needs to be nipped in the bud.
Roundabouts are a boon for contractors. So much more land, asphalt, cement, signage, curbs, etc to install for what was just a simple intersection.
You need your look at the lifetime costs and reduced property damage etc and it is cheaper in the long run
Very cool. 😎👍 As long as we don’t go roundabout crazy like France and start putting roundabouts in the middle of two lane roads nowhere near an intersection, I’m happy. 😃👍
The one thing I would change about that roundabout is to lower the height of the rocks in the middle. Drivers should be able to see the entire roundabout without any visual obstructions. I see a lot of other roundabouts that have too much "decorations" in the middle.
I believe the idea is to block oncoming headlights so nighttime drivers can see the road changes ahead
That's intentional. You have no need to see traffic straight across the roundabout from you. You only need to look to the left. If there's nothing coming, you enter. A car directly opposite you, is also entering the roundabout, and couldn't possible hit you as you enter. Unless you stop and wait before you enter .. whcih you're not supposed to do.
The issue with that is that it causes people to not yield but stop instead because "there is already a car there"
The band Yes has been telling them about this for 50 true summers. And finally…
Looks Great!!
I drove through this a few weeks ago!
In other words, they don't think your smart enough to handle an intersection. They're right of course.
We have a triple here in Michigan, it’s really fun in a semi
They SAVE lives, Every intersection with large volumes of traffic should only be around-about.
I feel like I've seen that intersection before. It used to be real bad!
This spiral design is an interesting solution.
Instead of one universal roundabout, let’s keep adding changes!
"NEVER stop in the Circle!"
What a great design. Well done. Never seen this clever layout before.
Australia has had these for a very long time. It's fair to say our government got a little obsessed with the idea and put them were they were absolutely not needed, tiny little back suburb streets with very little traffic. I think how this roundabout has been done is quite nice. A bit more elegance in the design . They do work in the right situations. Edit - Reading the comments below I have to say my nice comment was from an asthetic point of view.
A Turbo-roundabout is specific type of roundabout whcih hasn't been in use for very long (First on in the UK was installed in 2014) You have a lot of roundabouts in Oz, I doubt that you have many turbo-roundabouts.
It’s called a rotary. The word roundabout is properly used, “Y’all come down to my house roundabout 3 o’clock.”
We built 3 of them 4 years ago in bakersfield
What I enjoy most is every roundabout is different. Seconds to make a decision when traveling in a new area makes my day better.
What I enjoy most about roundabouts is drifting.
Try towing a travel trailer and navigating a roundabout in an unfamiliar area. Oh what a thrill!
Try it in a semi...
What happened to overpasses and underpasses? On ramps and off ramps?
An overpass interchange is a lot more expensive and requires a lot more land.
This roundabout is similar to the system what they use in New Zealand
Is diff nice
I see your turbo roundabout and raise you a magic roundabout a là Swindon UK!
These are rare in the US, the roundabouts. in many countries they are quite common
The problem is in this country no one nows how to use them
Ain't up to interstate snuff but it's a heck of a lot cheaper than an interchange.
Sidewalks? 🤔
why would you need sidewalks here, there is nowhere to walk to!
this intersection is in the middle of farm land so no pedestrians
truck aprons
We’ve got a few of these where I live in Arizona. It’s frightening how many tourists crash. If you’re ever bored, come to the big Harley Davison shop in north Scottsdale. And watch the daily shit show of horrible drivers. Lots of crashes. But at least they arent blowing a red light at high speed. I have no doubt they cut down on fatalities. But no way they cut down on collisions.
I think you’re off on date you need to look at LA by dodger Stadium on San Fernando and Riverside Road
That neighborhood has had that put in for over 10 years so sorry that is not the first time California has had this
Except no one reads the signs and panic at the last second. 😂
Remember the roundabout scene in European vacation? 🤣
There are several close calls just in this demonstration video. This roundabout would benefit from comically large yield signs on the approach.
It would benefit from drivers having experience with how they work. By definition, you won't find many those on the first of its kind in an area.
Please build more ❤️🙏🏻
In this video, I see cars straddling the solid white line which is not supposed to be crossed or touched at all. I also see a driver about to push their way into a space where a 40 ton truck is headed despite the truck having the right-of-way by both law and physics.
Truck still has to yield to those in round about. You can’t just push your way in if you don’t have a gap.
@@chrisstromberg6527 legally, traffic entering the roundabout must yeild. Physics, !!!FORTY TONS!!! no matter how much you expect a truck to stop in time at the slightest provocation, it will not stop like a Miata. It will stop like a freight train
Vehicles entering a roundabout have to yield.
@@chrisstromberg6527only to avoid killing the driver of the car. The car was supposed to yield to the truck. Car broke the rules.
would someone please explain to me the logic of calling a traffic calming device "TURBO"
New York State has given preference to roundabouts, citing reduced traffic backups. Indeed, it is amazing how many people will find alternative routes to avoid insanity.
If only the state would invest in educating drivers on proper signalling so that navigating these roundabouts was tolerable. But even this would not resolve the difficulties for pedestrians.
thankfully this intersection doesn't have pedestrians anywhere near it. Otherwise, complete cluster.
@@r2dad282 • My personal disdain for roundabouts stems from states that don't follow federal standards. For example, I was almost hit by a New Jersey plated car in a New York roundabout, only to find out that while our New York rules give right-of-way to those already in the traffic circle, New Jersey gives right-of-way to drivers entering from the right. Signage could help, but I would rather see uniformity, and it makes no sense to give right-of-way to entering vehicles that could bring traffic within the circle to a standstill.
Besides, in this day&age of "I just gotta check my cell phone!", I think there are benefits to old-fashioned traffic signals...
@@douglas_drewyeah, but I would rather someone crash into the middle of a roundabout then get t-boned at a green light because "I gotta check my phone"
@@illuminerd3757 • Absolutely agree. But I can't say roundabouts are the best alternative in each and every situation. Before I retired from DMV, discussions often took place with my counterparts in DOT and State Police on the pros & cons of each agency's areas of expertise. Balancing DMV driver education, DOT road design, and Police law enforcement is essential to overall reduction of accidents, injuries, and property damage. No one approach is always correct. Also, newer non-confrontational enforcement methods and technologies are available that can encourage overall safer driving, while accommodating all users of our transportation routes.
Safe driving to you and all of us.
As a tuck driver, I hate that roundabout. You have to sit there quite a while to find an opening big enough to pull your heavy load through there safely. It's dangerous.
2:09 red car completly missed the apex...
It's a roundabout!
Since when the hell is this new I’ve had these for 25 years all over around my town and to this day there is always an idiot stopping in it
It only took the US 100 years to realis roundabouts are safer and traffic flows better.
And cheaper
How many times has your country gone to the moon?
@@Sarge226 seems like a wack attempt to shift the conversation rather than directly rebutting the mockery. total non sequitur.. keep up
@dmnddy my city doesn't have roundabouts anywhere. But cities spread out around me have them and traffic flows much better, so I love them
It didn't take 100 years for our road builders to realize this. It took that long for them to start building them and ignoring the outrage from lazy American drivers that don't understand how to use them.
Title is false. This already exists in multiple places in California. There’s one in Tracy, CA that’s on the 205 and Grant Line Rd. Intersection, that goes on to the I-5.
Nope, yuou don't understand the title. A turbo roundabout is a specific roundabout design. The roundabout at 205 and Grant Line Rd in Tracy is not a turbo-roundabout.
Just a matter of time before someone speeding or drunk goes straight through. Should have made the center a much higher base, like 1-2 feet higher, and then put some grass on it.
Clicking on this not knowing if it’s a meme or a series video
you get blocked in if you use the left lane.
I mean most people only use the right lane, because they don't know or are just lazy.
No, you don't get blocked in if you use the left lane, the lanes spiral outward as you go around, so even the left lane becomes the far right lane 3/4 of the way around the roundabout. If you got in the left lane and wanted to take the next right, you screwed up and got in the wrong lane.
@andrewalexander9492 yeah, but the idiots
If this was somewhere in downtown LA I can assure you that there would be crashes there non-stop. People in downtown just don't know how to drive and it's scary.
you dont build this specific type of roundabout in cities anyways so idk what your point is aside from telling everyone youre from LA ?
Perhaps that's the problem ... decent driver training.
Is it true that driver training is just driving around cones?
@@Babihrse I guess it varies from region to region, but in Europe even driving a car requires at least 15 driving lessons from a driving school (ie not Dad). This costs a lot of money ($k's) However, in say NL or GE where the driving school requirement is in place, the death rate per 100k/yr is 3.1. In Canada it is 4.6 and in the US it is 11.2. Now, with the prevalence of selfish populist 'freedom' policies' I doubt if the North American nations would submit to such driver training even if it would most probably save lives, especially in the US. I think we need also to consider that the US has far more economic Darwinism and as such, I would expect a greater number of its citizens are comparatively more stressed or in a rush etc. We also need to compare the standards of automobile maintenance and certification. In Europe and some provinces in Canada, cars need to be inspected by a certified mechanic every year (certification). In Ontario, its only when the vehicle is to be sold. Many older cars cannot pass this and are junked. Driving such beaters may also increase deaths where this is permitted.
Ohh man these rounds are way too small.
Can not carry any speed thru them.
Makes it hard to decide when to get in or turn!
So what are the signs for? If they aren't emoji's how's anybody in that state gonna understand what to do?
Problem is right turn they give way when they can go out roundabout without any collision.that how we try do turbine roundabouts in europe
That's bullshit because the first roundabout was build in Patterson ca.
Look up Canberra Australia. 1000+ roundabouts 😅
I see more crashes in roundabout than lights
sick!
I don’t understand why they removed the capability to make a u turn from a roundabout. What the hell are you guys thinking
Because in order to stick to the design philosophy of a turbo roundabout (ie: enter the roundabout in the lane which exits where you want to exit, and remain in only that lane until you exit) the roundabout would have to have 4 lanes at each entry, instead of 3, and there would have to be an additional lane all the way around the roundabout, whcih would increase the amount of land required and the construction costs, which probably isn't justified for a maneuver that isn't all that common.
tractor trailers shouldn't' be pulling a YOU turn in major intersections.
I only hit the curb once in the beam
Looks like the one in Long Beach…
It was interesting, and confusing for others.
Why the turbo design instead of a normal spiral roundabout?
One of the problems drivers face is the amount of information that needs to be processed. With the Turbo design (I don't know better than that it is a Dutch invention) you only have to watch one lane at a time, one going in, one when exiting and then merging into a single lane. The design was mainly for a busy road crossing a less busy road.
A turbo roundabout design prevents most of the crashes that occur on roundabouts larger than one lane. It does this by by preventing drivers from making Lane changes within the circular roadway
Glad they built this turbo roundabout correctly, with raised lane dividers.
My area just had a single-lane roundabout increased to two lanes with only painted lane markers, and I’ve already nearly had my front left fender clipped by a large white pickup cutting through the lanes at high speed to get around my left and then dive across me to exit, completely ignoring the lane markings.
Multi-lane roundabouts with only paint separating lanes have some of the same issues traffic circles do. I’m trying to convince the local engineering departments to implement the mountable raised lane dividers. They’re concerned about snow removal, but these have been used in Scandinavian countries for decades and they manage that task fine.
This is a normal spiral (turbo) roundabout. Normal multi-lane roundabouts are concentric circles, not spirals.
Because nothing beats that little whoosh sound when you let off
