Road Segment meets zero, one or many Intersection
Intersection is met by one or many Road Segment
A Road Segment physically meets at most two Intersections, feeding and collecting traffic from each. With two Intersections, we see one at each end of the Road Segment. But two are not always visible. On a long Road Segment, the Ego Vehicle might see only the one in front or the one behind. And on a stretch of freeway it is quite common to not detect any Intersections.
An Intersection cannot exist, on the other hand, without interfacing with one or more Road Segments.
