A traffic island is a structure separating at least two lanes of a highway for a short distance. The width of the island is usually under a few meters.

The island doesn't necessarily have to have a right-of-way indicator. For islands at junctions or traffic lights this tag is also appropriate.

How to map

Apply a node at the object, or draw a line on the object.

Don't let this image fool you - there is no indication of a right-of-way, so this is a traffic island, not a roundabout


  • One possible rendering may be as a small hollow dot in the middle of a node, or a small hollow line in the middle of a way. When creating software, these choices are yours.
  • None, currently, by the osm-carto layer.
