Yeah. So it is all very well and good til someone loses it or disregards or just doesn't care about the road rules. I hate multi lane roundabouts. And if the AI are doing this in a model God help us in real life.
Multi-lane roundabouts are logically flawed because they typically are attempting to accommodate two lanes of continuous travel in each direction. The typical posted traffic rule is if you are in left-hand (inside) lane you must turn left or continue straight and if you are in right-hand lane you must turn right or carry on straight. This works fine for vehicles in the right-hand lane making a right turn, since they only have to yield to traffic that is in the outside lane of the roundabout. But for all traffic continuing straight through or making a left turn it requires yielding to both lanes in the roundabout before entering it - this is necessary so that traffic approaching the roundabout in the NB direction in the inside lane and continuing straight does not interfere with traffic approaching the roundabout in the WB direction from the outside lane continuing straight. Effectively, this treats both lanes as a single vehicular lane that just so happens to also accommodate right turning traffic. The other glaring problem with having two lanes available for continuing traffic is that the vehicle using the outside lane must have xray vision to see through the vehicle in the inside lane to determine if there is already traffic in the roundabout or not. In other words, there is no point in having two lanes in the roundabout since no vehicles can ever, theoretically, be travelling around it beside each other. The only exception is if the cross-road has very low traffic counts (in which case a two-way stop would be much more cost effective). A better use of roundabouts to reduce the need for signalization would be for all traffic in the right-hand lane to turn right, with channelized turn lanes, with the single lane roundabout reserved for all continuing and left turning traffic.
I completely agree with this. We got our first roundabout a few years ago in the town I live in. I had previously driven through single lane roundabouts and understood their purpose and effectiveness. The one we got, however, was a a 2 lane roundabout. I couldn't understand what the purpose was of the second lane. Also, in a town with no roundabouts, why start them off with a 2 lane model?
3:45 cars didn't even yield to other cars already in the circle. Cars in circle stopped otherwise would have got cut off and had an accident. Sort of what happened to me today.
I can count dozens of times in which the cars waiting at the bottom of the picture can enter the roundabout without cutting anybody off, and yet they sit there like a potted plant while 10 or 11 cars pile up behind it. Unrealistic to the extreme.
Something is wrong with this roundabout.There is an entry on a lanes and the exit to the right is done on two lanes, while the others are on two lanes both at the entrance and exit. So this roundabout is wrongly designed. So refres the animation in which all entries are on two lanes and circulation will change in a more fluid way. And something else. There is no signaling of cars at the entrence and the exit which is mandatory. Have a good day.
2:03 At the right of the screen, the white car incorrectly enters the roundabout in the right-hand lane, in order to make a 3/4 way around left turn. This results in the white car stopping in the roundabout (in front of another entrance to the roundabout) while waiting for traffic in the left lane to pass before moving into the inside lane. Isn't it illegal, or incorrect, to stop in a roundabout and change lanes in a roundabout?
These roundabout's are safe if all drivers are sensible but they are not, the moment you think all drivers are sensible that is the time you will get a bump. Better to assume someone with do something silly this will increase your chances of avoiding accidents. thinking this way has help me survive roundabouts lol
LOL! For Red Deerians, you must first explain how to find that little signalling device on the steering wheel, how to use it, practice using it until it becomes a habit and then maybe you can graduate to a traffic circle. Good luck with that!
What lala land is this from? This not the way people actually drive, stopping and waiting for circle to clear. And directions all say supposed to be yielding to traffic, merging but NOT stopping, riiiight. Everyone in a big ass hurry, texting on their phones, and continuous flow of traffic, the circle is not going to be clear.
Canadah, where traffic is light. europeans treat it as a two lane interstate. To exit you have to be on the outside lane. And you have to get into the inside lane to go past straight ahead.
If you are on roundabout - Please indicate you intentions - right winker for 3rd exit and left for exit - its so simple and so safe - assuming intentions cause a lot of errors/accidents Guessing is not unusual
3:34 red car didn't have right of way and was supposed to yield to drivers already in the roundabout
+theawesomedude1029 Totally
I fell asleep at 0:34
0:29 The blue car closest have many unused opportunities to go.
Road rage, totally. He crossed the solid white line and then cut off that black truck.

3:48 white car on South end of roundabout does not have the right of way to stop in the middle of intersection. #StopWhiteCar2015
it was not given priority by others thus that was needed in order to prevent an accident?

Two lane roundabouts should have two lane entry/exit points as well.
Normally,they have

kind of a bad demonstration considering that insanely backed up traffic coming from the bottom of the screen.
Nic
i agree. everyone there is too timid and even when there's a gap in the traffic they still sit there
This is not realistic. Where are all the accidents?
AHAHAHAHAHAHAH THAT LONG LINE OF TRAFFIC, JUST, HOLDING UP EVERYONE ELSE, HAHAHAHAAHAH

I Don't want this kind of intersección on SR64 and Rye Road on Bradenton, fl. But if it's safe and saves lives welcome

How about two lane double roundabouts? Those are crazy
is this for the uk roads and roundabouts, cause im pretty sure we drive on the left and go clockwise around round abouts
+leevinylcritic You have answered your own question. This is for mainland Europe.
@@alexbarlw1
NO WAY! This is a design used only in the USA.
Subsidized by the local car repair shop.
Designed for disaster...
I am driving right across that round thing, shortest route.
Very good video ! 👍
Ugh why can't they design these things consistently.
Very important for beginners driving
P.S. What you are doing with your life is an inspiratin to all! Keep touching me
Much prefer the french way. Far more practical, especially in heavy traffic.
I hate these damn things. People never yield.
Enjoying
Might I add that 2+ lane roundabouts are completely stupid and un-intuitive.
i am THERE
american can do this.
