What is a Modern Roundabout?
Simply stated, a modern roundabout is a transportation management tool that moves traffic through an intersection without the aid of traffic signals. More specifically, a modern roundabout is an intersection with one-way circulation around a central island where entering traffic must yield the right-of-way to the traffic circulating within the roundabout.
A modern roundabout should not be confused with traffic rotaries or circles, which are much larger, with higher speeds and multiple lanes for entering and exiting. As traffic volumes increase, collisions and traffic jams can occur because vehicles are not required to yield to traffic before entering.
Traffic engineers recognized the deficiencies associated with traffic rotaries and circles, and incorporated slower speeds and "yield on entry" into modern roundabouts. for more click here |
I have supported this concept since the first roundabout was constructed.
The most extreme cases are where the two lane roundabouts have exiting into a single lane. So what we have here is perhaps two cars side by side in a two lane roundabout with both trying to exit into a single lane street. If this isn't dangerous, nothing is. This can be viewed at the Morse/Rte 441 circle. The safest solution is for all vehicles to navigate the roundabouts is by staying in the roundabout outer lane.
