Creating a roundabout from an intersection
Often times, when streets become more congested, planners will install a traffic circle, or roundabout, to get traffic to flow more freely. This section shows you the steps to get from an existing intersection to a new roundabout.
The situation starts out like this, where the roads are no longer aligned with the new plan, and now there is a roundabout which we need to get created in Waze:
This situation is fairly simple because all the segments are connected together already.
The first thing to do is move the junction to the center of the roundabout. This is as simple as it sounds: click and drag the junction to where it should be.
Once the junction is in the correct place go ahead and save the work.
toolbar and click Roundabout. You can also use the keyboard shortcut which is the letter o, selected because the shape of the letter is round, like a roundabout.
WARNING: Any segments completely within the roundabout area WILL BE DELETED.Updating details to confirm the road section for details on this process. In Waze, we do NOT name roundabout segments. These segments remain unnamed using the "No Name" checkbox for street name to enable proper routing. If the roundabout is a named circle on local signs, then add a Place area type set as a Junction / Interchange filling the center area or covering the roundabout as appropriate using the name that appears on the local signs.
When the process is complete and the Save button has been clicked on one last time, this is how the new roundabout looks:
For further reference, please watch this video on roundabout creation.
Oval and very large shapes
If an oval or elliptical roundabout is required, hold down the Shift key. At this time only oval roundabouts along the North/South or East/West axis can be created. If an alternate shape or axis is desired, create a circular roundabout that is close to the correct shape and adjust the geometry nodes manually.
Note that roundabouts cannot be created over a maximum of 100 m (328 feet) in diameter because of the danger of erasing all roads in the center could accidentally wipe out an entire city of roads. If a larger diameter is required, use the same steps described above to alter the shape by adjusting the nodes as required.
