Just a quick follow-up here. I've been seeing the same problem and have taken steps to correct some local roads in Oxford, but without success.

One example is the Northern By-pass Road. The south carriageway is perfectly runnable, with a wide path. The northern carriageway is high speed vehicles only, so not runnable.

A few months ago, I adjusted OSM to reflect this. This is now shown correctly in overpass-turbo.eu, but not in StreetFerret. Do I need to make additional changes to the road in OSM or is there an issue with the parser/database of Oxford roads?

I've put a couple of screenshots on imgur, but can't link directly (not enough posts). The URL is https :// imgur . com / a / YzTm1l8 (without the spaces).

I've obviously not run the northern carriage way, but it's still showing as something that I could run.

Thanks a lot.
