Likewise, when "segment" is being used in sense B), the object with a junction at either end is being referred to as a "road".
Sense B) is wrong across the board.
A "segment" is a map object with two junctions--one at each end--and zero or more geometry nodes that alter its shape from a straight line connecting the two junctions.
A "road" is an identity in the map database that is associated with one or more segments.
As far as I know there is no name for the straight section between two geometry nodes (or between a junction and a geometry node)--nor does there need to be. The only time I have seen its lack of name become a problem is in this thread, when we tried to name it.

Sections is much better.

Which leads to Waze developers not understanding what we're talking about.kentsmith9 wrote:bgodette wrote:Here is where the problems begin: In the data model used by WME and presumably routing, Junctions are what we call roundabouts and Nodes are what we call intersections or junctions, and geometry "nodes" are a list of Points contained in the geometry attribute of a segment/landmark.
In that case should we just use a convention that makes general sense and follows what we have been saying and using all along?
