Hi, The names seem more like descriptions of the features. The use of the level tag is incorrect. Some features are untagged. The outline Way: edision block (354741132) has very unusual tags. Thus I would suggest this changeset be reverted. You can then learn a bit more about editing OSM and especially editing with the complex JOSM editor.

My attention was initially drawn to the steps area in the SE corner. Where highways are duplicated one atop another. They have the tag level_name=0, what does this mean?

There are many guides and videos to help with JOSM. Need any help please just ask.

Regards Bernard.
