→Ramp and interchange style
Before the current house numbering system came into use, transition nodes were used to aid in house numbering, but that is no longer required.
There may be existing transition nodes on the map for other reasons like remaining after a connecting road is deleted, inherited from
to the original base map import when rivers and streams created junctions, etc.
As long as you are '''certain''' it is not a valid transition node, a superfluous junction node may be [[Map Editing Quick-start Guide#Delete a Junction|deleted]]. Doing so will simplify the map, eliminate turn restrictions to maintain, and reduce computing resource needs. Also consider removing the [[Creating and editing road segments#Adjusting road geometry .28nodes.29|geometry node]] which will replace the junction node you delete, if that geometry node is not needed.
