# Part of a [[#Loops|Loop Road]]
An old reason to use a transition node was to indicate segments of the road with different house numbering. With the new point numbering scheme being adopted by Waze, this is no longer a reason to use transition
There may be existing Transition nodes on the map for other reasons (left after a connecting road was deleted, inherited from to the original base map import when things such as rivers and streams created junctions, etc.).
