And yes I'm not happy with my change either cause it's still doesn't look good. I would probably change how way/502767563 is connected and join to way/894689761.

I find my self it's almost the most difficult intersection I saw, so I would love to get help with it. Please bear in mind that situation is not about visuals it's also about getting mapped correclty road restrictions and lanes information.

Yes, conversation start from the bug in OsmAnd. Though I never edit map to fix the issue, it would be insane.

The issue I was trying to fix by looking at Satellite Imagery that roads (or better to say traffic trajectory were far away from realistic).
If you compute the route and it looks like Zigzag that doesn't mean that roads mapped correctly.

Let me give you an example at location I know better (osm.org/#map=19/52.28686/4.83592). Here it could be mapped as straight perpendicular arrows but that doesn't reflect reality and it doesn't make sense to make it like that.

I wouldn't say I know what it goes here but I suspected that going from SE (motorway) to NE (Landsrasser Hauptstrasser) doesn't imply you need to go to the center of intersection, so introduced that link that it connects with a better geometry. Another main issue that moving from NE (Landsrasser Hauptstrasser) to SW (Franz).

I mean I wouldn't care if OsmAnd has a bug in 1 place in the world. I'm thinking more about OpenStreetMap, so traffic trajections are mapped more realistic. Cause in the end we could every interesection map with a single point but that won't make us happy.

Hi,

I don't think they are done for the rendering. They are done to be more aligned with real data on the ground.

Could you please specify what's wrong with the change cause the road intersection is quite messy here.

There are multiple forbidden routes and turn restrictions do not reflect all situation here.
