Paired Conduit
In two way traffic we have a Conduit flowing traffic one way and another Conduit flowing traffic in the opposite direction. Since both of these Conduits are adjacent to one another and describe the total flow of traffic on a Road Segment, we consider them to be paired.
See the Road Segment description to see how left and right sides of the Road are determined for Roads crossing at various angles with respect to the Ego Vehicle’s location and heading.
- Road segment + Orientation
In a Two Way Road Segment, RS1 let’s say, we’ll see two Conduits: RS1-F and RS1-R. So we can easily tell them apart using these two components.
The choice of subclass, Forward Paired or Reverse Paired is determined with respect to the Ego Vehicle’s current Conduit (which is always forward regardless of the Ego Vehicle’s momentary orientation, see Forward Paired Conduit description) or where the Ego Vehicle may proceed as it travels in the legal direction of traffic projected from its current position.
