R2 / 1:1
Two Way Road Segment has forward flow of traffic defined by one Forward Paired Conduit
Forward Paired Conduit defines forward flow of traffic on one Two Way Road Segment
By itself, a Two Road Segment is just a strip of pavement, maybe with a Median in the center. The Forward Paired Conduit is the rule that all traffic must flow in one direction within one or more adjacent Lanes. So we are pairing a physical structure (the Road Segment) with a policy (Conduit).
The assignment of forward and reverse depends on the location of the Ego Vehicle. See the Forward Paired Conduit class description for a more detailed explanation.
