[OSM-talk] Non-junctioning crossing roads

Be careful. The question about the junction node is NOT about routing
but about physical modeling. Even if both roads are not allowing
turning left or right, you have to add a junction node (and the
relations about turning restrictions), othewise we will interpret them
as being at different levels and perhaps the tags "layer" and "bridge"
are missing. It is the same if a road is crossing a railway : add a
junction node if they are at the same physical level (then add the tag
junction=crossing or level_crossing) and DON'T create a junction node
if they are at different levels (then add the tags bridge/tunnel/layer
as usual).
