    I'm impressed that this viral idea managed to integrate the worst aspect of cloverleafs (overlapping lane crossing in both directions) with the worst aspect of roundabouts (the lack of express lanes). It's efficient design in terms of maximizing disadvantages.

      If the junction is double strong-shaped, double is the efficiency of course.
      If it's efficient in a positive or negative way is only up to how much of an architect is the one in charge of the project.
      It can be either 2 times better or 2 times worse than a regular non-strong-shaped intersection.

    The turbo roundabout should not be double lanes. Should be singular lanes. Also the lanes on the inside are not fully connected. They stop 3/4th of the way to avoid giving way a million times. In the Netherlands you got plenty if these roundabouts and they work perfectly fine.

      not sure if these are like you mention, but what i see with a turbo roundabout is one where the lanes keep moving outwards. so the first lanek goes 1/4 of the way, 2nd lane goes 1/2 of it. a very good exampel of this is Kooimeer roundabout in Alkmaar. each lane goes either rigtht or straight and as there are 5 exits, there is a total of 5 lanes on it to enter

      ​@@bananagaming7612they are not necessarily better, just different. It is not four way symmetrical, there's an orientation to it. So it is quite useful when a busy road meets a less busy road. The busy road remains 2 way all the way thoughout for going straight and only needs to worry about 1 lane of traffic coming in and having to give way for. The less busy road only has one lane to go straight (the right lane is a right turn only in a right side of the road model). Since in a lot of real world cases a roundabout is a place where a less busy road crosses a more busy road, it makes sense in a lot of places, but it's definitely not always better. (Most roundabouts are 1 lane anyway, in which case you literally cannot build a turbo roundabout).

    I don't know about anywhere else but in the US (at least in New Jersey) , when there is a very short merge onto a fast moving highway, there is often a dedicated Lane for a few hundred feet so the car can build up enough speed to merge into traffic. Obviously the merging cars still have to wait until there's a break or feel confident enough but, that crashing issue at first would probably be handed out at least mitigated by an addition of a brief extra lane for the cars to merge and yield should they have to.

    So, I live in Metro Detroit, and all of our major intersections look like that. The difference is that we still have stoplights, so people can just go straight. You can’t turn left at the light, so if you want to turn left you have to use turnarounds by making a right, or by going straight through the intersection and using a turnaround (if it’s a large divided road of the same design). We call those “Michigan Lefts” because we love turning right on red, and from a turnaround it’s also legal to complete a turn if the traffic is clear.
    That said, there are interesting situations where having intersections built like that are helpful. During a power outage, cops will often park in the middle of the intersection to block anyone from driving straight through, which turns it into exactly the thing you saw in that video and recreated. My area has an annual street cruise, where they block off a lane and several turnarounds for classic cars only, in addition to blocking the traffic from traveling straight through on the smaller crossroads. It’s annoying because you have to drive over a mile out of your way because of the event traffic, but it allows for a consistent (albeit slow) traffic flow, which is far safer than trying to drive through an intersection that size without the help of the lights to cut the flow. Sometimes there are lights that hold traffic using a turnaround, because there’s just too much traffic for it to be possible to continue without the assistance of the light. At less busy times of the day, it turns into a blinking red, and often at very busy intersections they will post a sign that says “No turn on red” at the light where the roads meet, and sometimes at the light they put at the first turnaround.
    I’ve seen smaller cities in the state (several hours north) where they don’t have much real traffic, and they do goofy shit where they allow people to turn in addition to making a proper “Michigan Left.” Those intersections have accidents, because they’re subverting the expectations of how those divided roads and their massive intersections function.
    We basically don’t have any mass transit in any part of the state, because back in the day, the automakers made sure to shoot down any attempts at that, and they influenced Detroit’s politicians to get rid of the fairly shitty, electric street cars, that were ridiculously unsafe for pedestrians, because they were in the middle of the road. So people would run from the curb out into the middle of the street while they were stopped, and it wasn’t like they were necessarily timed with the lights, so these things would block up the turn lane, in the dead middle of the road, and they would hop on or off whenever it slowed down, while there were cars zipping around in all directions. It’s amazing that more kids and older idiots weren’t killed. I think the reason they got rid of them was because the overhead cables looked like shit and prevented taller vehicles from traveling through the areas where the streetcars were, and I’m sure it chapped someone’s ass that deliveries had to go around or be offloaded onto smaller vehicles for the last leg.
    Honestly, I think you’d get a kick out of looking at some of the ways we build roads here in Detroit, because we’ve been doing it pretty much longer than anyone and solved a lot of the congestion problems ages ago. The divided roads with turnarounds are great, because even if traffic is so bad that you literally can’t get across all the lanes in order to make your turn, you can keep left and go through to hit the turnaround just past the intersection, or if you made the right, but can’t get over to the left because of a backup caused by construction or an accident, or something, then you can keep going straight and working your way over to the left lane, and just use one of the other turnarounds a little further from the intersection. It sucks going just a little bit further out of your way, but it sure beats sitting still with a turn signal on, while holding up traffic in order to get over. Of course, there are morons too stupid or too rude to do that sometimes and they will try to force their way into the line of cars-but those people make your architects look like saints or engineers by comparison. Literally the worst of the worst that even pedophiles can fairly claim to have moral superiority over. Sadly, these oxygen thieving dregs aren’t as easy to spot walking amongst us, otherwise we would’ve sorted out their ilk a long time ago with some sort of human rights violation or war crimes.

    Turbo roundabouts are fairly common in Spain, but they are a lot simpler than what you built, they're nice because they eliminate the problem of the car on the inside wanting to turn out while the one on the outside wants to stay in. Most of them have traffic lights, though to be fair, most urban roundabouts in spain do, we even have some horrid roundabouts with traffic lights inside the roundabout for the cars inside it to give way to cars coming in.
    In southern Spain (mainly Málaga) I've also seen roundabouts where the main road goes straight through the middle sorta like this Ø and imo they are a mess of traffic lights and worse than a regular roundabout in every way, but I'd love to hear your thoughts on them

    • @gwalla
      @gwalla 11 месяцев назад +17

      It's really meant for limited-access expressways, not fully controlled-access freeways. The idea is that you're trying to prioritize through traffic on the major arterial as much as possible, while traffic on the cross street is mainly feeding the arterial and through traffic on the cross street is minimal. It's very stroady. It's really just a step up from the Michigan left (I guess in left-handed traffic, that would be a Michigan right?) except the minor street is fully severed in the middle so even traffic proceeding across the major street has to take the inner u-turn slip lanes instead of meeting the major street at a two-phase light.
      It's called a "superstreet" (no, really). The basic design doesn't have those outer u-turn lanes though. Matt's right, they're completely redundant. Even if you did need to hang a U, you'd just proceed across and use the inner u-turn lane.

  • @Soporbum42
    @Soporbum42 11 месяцев назад +26

    The U-Turns make sense if this is a separated road with many access points. When you enter the road you can only go one way (left in your case) and if your destination is to the right, you'll have to go to the next interchange or roundabout to turn around. There's a system called a "Michigan Left" that is kinda similar to this but with signal control. Growing up with them all around, the idea of turning right to make a left is not so crazy to me
    Also, to get the asymmetric road to go the way you want, click hold and drag in the direction of traffic you want to have the extra lanes

    The first, rectangleabout works well when one direction get a large majority of the traffic and generally doesn't turn. For example a highway with a rural route cross street. Highway 15 in Maryland is 22 miles of sequences of these. There are no stop lights so the highway keeps going and each of the small roads can only go right. It works well.
    The turboroundabout can work but requires lots of signs and either needs to be very large or have slow traffic. Dupont Circle in Washington, DC is a well-known one.

    Clover leaf - mythical reasoning for their use. Heavy snowfall, plowing. Snowplows only have one bridge over traffic that would potentially drop snow on the lanes below. All other intersection designs have multiple bridges where snow would fall and impact traffic flow. Bridges cause icing and more bridges also creates more opportunities for crashes above and below on the ramps. More snowfall maintenance required. Verification needed.

  • @gothfalcon
    @gothfalcon 8 месяцев назад +4

    The first one is a benefit for heavy urban areas where there is a median that keeps you from trying to get to the other side of the road you are on, so instead of adding traffic to the roundabout as you make your way all the way back to where you started, you can avoid that. It would not be good for something like highway traffic where there's no reason to turn back around.
    The main benefit of cloverleaf intersections is that you don't need extra bridges. If you're just dealing with paper or a simulation, it doesn't make sense, but it's one of the most cost efficient high speed designs for highway intersections with how little bridge work is needed. That's why they are all over the place in the US where things are spread out so a lot of intersections don't have very much traffic comparatively. Plus we would have even more bridges that need to be repaired or replaced if we had other intersections

      It's the one flaw in the design of turbo-roundabouts. Once you're in the wrong lane, it's hard to stay in the roundabout and get to the exit you wanted. Though I think the Keizer Karelplein is peak perfection when it comes to roundabouts. Bicyclists and pedestrians are protected by traffic lights, and cars get anywhere between 2 and 7 lanes of space as is needed. It's just the tourists who don't pay attention and do daft things that makes it dangerous.

    The turbo-roundabout might work better with less lanes, and also by connecting it up correctly.

      I think they're planning on installing two of them near me on either side of the highway. And yes, it would be 2 lanes. Both lanes allow going straight through the intersection, but the right lane for right turns and the left lane for either u-turns or left turns. I'm assuming that's more or less what you've got. This type is new to me here in America. It's only been in the last 10-15 years that the local DOT has started installing proper roundabouts.

    This is used significantly in Baku, Azerbaijan. From what I saw, they are much larger, providing more time for “lane swapping”, are generally four lanes in each direction, and since it’s not always practical to have an intersection where roads meet, you instead are forced to enter and turn right with traffic, then just go up to the next u-turn and go back the other way. It’s true, I don’t think it’s the most efficient, but it really wasn’t that bad, when trying to expand on existing and crowded infrastructure.

    13:55 as a dutch person (no engineering degree but doesn’t matter here) the turbo roundabout is intended to remove weaving accidents on multiple lane roundabouts, and create faster through traffic from the highway onto the by-way. It isn’t very standard but quite common when there is alot of flow in 2 directions from the roundabout and not alot from the other two directions. For other situations, lots of traffic in 4 directions we tend to use traffic lights or a proper interchange.

    The cheapest intersection that provides safety is the roundabout. The cheapest and fastest for cars is the 4 way stop (assuming no signals for either).
    If AI are able to follow road rules perfectly, then you can make a bidirectional roundabout that is more efficient for car movements (kind of similar to the idea of a turbo roundabout). Yet this means human drivers have at least 2x more opportunities to fuck up.

    In Long Beach, California there exists a roundabout originally created in time for the 1932 Olympics to handle the increased traffic volume in the region. Five streets meet here: Pacific Coast Highway (twice), Lakewood Blvd, & Los Coyotes Diagonal. The intersection has been adjusted a few times over the decades but now includes a partial turbo section that I think still invites confusion, particularly travelling northbound on one of two lanes on PCH entering just before Los Coyotes. Inner lane people sometimes enter the round into the outer lane, cutting off outer lane people, & needing to exit onto Lakewood Blvd northbound. Maybe this was the best solution to a difficult traffic problem.

    The u turn bits are a way to avoid having intersections elsewhere nearby on the road and to avoid building overpasses/underpasses. They only function properly when there are other similar intersections, or at least similar u turn spots, on the same road. Also, the spots where cars were merging and going through each other can be made 100x better by having 2 lanes going off. That way cars only need to change lanes if they want to go straight or go around the other side. This intersection is literally just a square roundabout with u turn lanes before the roundabout.

    This intersection is a roundabout... Ok, rectangleabout... Only you don't have to go completely around it to go back the way you came (which every roundabout gives you the option to do), which reduces the traffic on the roundabout itself.
    The problem is the tight turns and the fact that people wanting to go back the way they came is a tiny fraction of the traffic.

    We have some roundabouts like that turbo roundabout where I'm at (us). Usually used at intersections with a four lane main road (two each way) and a two lane road. Your main road keeps two lanes each way, right lane for right and straight, left lane for straight and left. The minor road only has one lane(except an occasional right turn only onto the main road). On the minor road the one lane goes every direction. I think whatever you were trying to set up was more complex than it was supposed to be

    Had a thought: maybe a collab with Biffa. 2 engineering minds doing a traffic management challenge, or bouncing ideas in a video series. Would be a cool video!😊

    I'm pretty certain the reason for wacky designs, is that even the most efficient roads can become clogged, but some people just can't accept that.
    The real solution to too much traffic, is to have less traffic, as in create modal shifts with things like buses, or trains.

    This new design is indeed free of traficlights, but it doesn't do anything to mitegate the amount of points of conflicts in the setup. Also, I'd at minimum add two bridges crossing over the middle so if you are arriving at a wider side you can cross over immidiety without having to do a big driver-around to get through.
    The turbine interchange is far supperior in that there is little to none points of conflict in the layout if done correrctly. The problem however occours if too many vehicles tries to use the same one exit

    I think the idea with the u-turn lanes is so that this interchange can scale to different situations. If it's being marketed as a "Roundabout Killer" then it would need to serve all of the same functions, U-turning being one of them. I've definitely needed to make a u-turn in a roundabout before. On a highway it may not be necessary but if you're getting more residential or rural cases (if you have a rural road with farms off of it, it can be easy to miss a turn especially if there's shrubbery)
