[Transportation] OSM junction=roundabout missing access restrictions

[NPolster]

Hi,

I’m encountering a problem with access restrictions for roundabouts. In OSM, roundabouts often don’t have the attribute oneway=yes, which means they are frequently missing access restrictions in OvertureMaps. This causes routing issues, as routes are currently being generated against the intended direction of roundabouts.

Here is an example:

Overture: https://explore.overturemaps.org/#19.31/47.7533986/8.852229/0/16 (ID: 08a1f816532d7fff0474b28f72791a22)
OSM: https://www.openstreetmap.org/way/1032682701

In OSM, roads within a roundabout typically have the tag junction=roundabout. Would it be possible to either include this junction information in the Overture data, or to automatically generate access restrictions based on that tag?
Alternatively, is there currently any way to identify that a segment belongs to a roundabout in Overture?

Hi @NPolster, thanks for the feedback. We don't currently have a way to capture this information, but I think it would make sense to add, possibly as a road flag. Would that be sufficient for your use case?

Hi @brad-richardson, thanks for your feedback! If this would be added as a road flag, it would be perfect for me.
