Click at the point and click at Node link to open new tab with feature that needs to be edited
Edit data in either JOSM/ID Editor (iD is recommended for this task)
Delete highway:mini_roundabout tag from junction using
button
Use right click at the node in the middle of junction
Use Split function from contextual menu by clicking at
button
Right click at the same node again and use Disconnect function by clicking at
button
Now make some empty space for new roundabout like it is presented here:
Begin inserting the circular features by mapping simple rectangle:
Right click at the way of that new rectangle (click in the middle of two nodes) and use Circularize function by clicking
button
If necessary, move roundabout to center it with imagery (
icon from contextual menu) and adding correct tag to geometry:
highway=*
junction=roundabout
Each entry and exit way should join the roundabout at a separate node.
surface=* (where possible from Aerial Imagery)
name=* (IF there is a name specific to the junction add)
maxspeed=* (If possible from a corroborating source, if not leave it)
No need to add oneway=yes tag, as this is implied by the junction=roundabout tag. IF you are drawing roundabout from left to right. If you don’t, you have to put oneway tag.
Sources to check: Aerial Imagery, GPS tracks, Strava
The goal of this task is to model min-roundabouts consistent with the Australian tagging guidelines.
This overpass query will identify nodes tagged as mini-roundabouts. https://overpass-turbo.eu/s/tUh.
