I disagree. This is too complicated. The problem is to specify that a junction has a name, and to disambiguate these from any other junction. Right now we have a mechanism for this when the junction is a roundabout: junction=roundabout name=* In the wiki is was stated that named junctions can be marked with: junction=yes name=* However, Mapnik does not render a label for this. I'm not sure if any other renderer does. Mapnik *does* render a label for a named roundabout. To add a junction name we could just add a name=* tag to the junction node, but then there is no hint about what the name means. So, by adding junction=yes it indicates that this *is* a junction, and the name is the name of the junction. It's simple and obvious. junction=crossroads would be fine, but it doesn't add any information. junction=yield is no good because it does not specify which direction of approach should yield. junction=stop is also no good, for the same reason. So, what I want is for Mapnik to render a label at a node if the there is a junction=yes tag (and name=* tag) present. This has been stated in the wiki for a long time.
