Maybe someone likes to improve the car or truck routing experience with #OpenStreetMap. I just compiled a list of ~3200 links that very likely highlight tagging issues. Either overlapping roads or missing turn restrictions.

Right click the map and click Query OSM to easily go to openstreetmap.org.

If someone is interested in another country than Germany or the entire planet - let me know.

@karussell Could you indicate what the problem is with https://graphhopper.com/maps/?point=48.415107%2C11.634849&point=48.41561%2C11.634938&point=48.414178%2C11.633768&profile=car&layer=Omniscale

@pbb Probably nothing. I have a heuristic that searches for very small angles without a turn restriction. (unfortunately I made a mistake and need to re-run this to really cover the missing turn restrictions)

@karussell I would think this is allowed: https://graphhopper.com/maps/?point=48.106405%2C11.697063&point=48.10634%2C11.696902&point=48.106405%2C11.697063&profile=car&layer=Omniscale

@pbb Yes, this is allowed but this case here highlights an overlapping way problem:

https://www.openstreetmap.org/way/1304392264

https://www.openstreetmap.org/way/1154677977

This case is also not really a good example (it seems to be very common for area=yes and so I have this usually excluded). But see e.g. this one:

https://www.openstreetmap.org/way/98603597

https://www.openstreetmap.org/way/1221554189

@karussell Interesting with overlapping roads! That is indeed a problem that needs to be fixed.
