If an observation site is located at an intersection of road segments, the data shall be collected from the sampled road segment, not the intersecting road segment(s). (2) Roads with two-way traffic. If an observation site is located on a road with traffic traveling in two directions, one or both directions of traffic may be observed, provided that— (i) If only one direction of traffic is observed, that direction shall be chosen randomly; (ii) If both directions of traffic are observed at the same time, States shall assign at least one person to observe each direction of traffic.
