  • I discovered roundabouts when driving in Ireland in the spring - they're awesome for keeping the traffic moving. I welcome them here. Excellent video demonstration.
  • Vehicles from access roads are included in the rotor traffic, respecting the right of priority for vehicles already moving with the rotor. The advantages of the rotor compared to other forms of single-level transitions are increased safety due to the lower speed of the vehicle passing through it and better visibility and higher throughput.
  • How come the ones in the inner lane change lanes? That can't be right!
  • @peter1062
    Traffic lights defy the purpose of a roundabout. And where are your pedestrian crossings and cycle lanes?
  • Ono što me uvijek izbacuje je koncept "izlaska iz unutarnje trake". Da biste to postigli, uvijek u posljednjoj sekundi prelazite vanjsku traku što uzrokuje zbunjenost.

    I have never seen a traffic signaled roundabout before, I thought roundabouts were an alternative to traffic lights, but not both at the same time.
  • If there's 3-lane roundabout, what's better for managing traffic is this: Right lane for right turns and straight ahead only, middle lane for straight ahead and left turn only, and left lane for left turn and U-turn only. How safe is that suggestion? Also, drivers must yield to pedestrians. Edit: Whatever you do, changing lanes in the circle is illegal. Turn signals are required.
  • Here is what I never understand about a multilane roundabout. If you want to turn left, then you have to go to the inside lane which means that you have to change lanes twice before you exit. So first of all, why do some people say that you can't change lanes. How are you supposed to get out of the inside lane without changing lanes? Secondly, I always thought that drivers were told not to change lanes on sharp curves because your sight distance is limited . Usually when a driver approaches a section of a multilane road with a curve in it, the lines between lanes change from a dotted white line to a solid white line to tell drivers not to change lanes in that section of road. A roundabout is a circle which is obviously curvy. Therefore isn't it dangerous to change lanes on a roundabout, but if you wish to turn left it is unavoidable. I keep hearing people talk about how roundabouts are so much more efficient and safer than other intersections but this is the biggest flaw to roundabout designs.
