Analysis Boundaries
The intersection analysis boundaries are not defined at a fixed distance for all
intersections. Rather, they are dynamic and extend backward from the
intersection a sufficient distance to include the operational influence area on each
intersection leg. The size of this area is leg‐specific and includes the most distant
extent of any intersection‐related queue expected to occur during the study
period. For these reasons, the analysis boundaries should be established for each
intersection according to conditions during the analysis period. The influence
area should extend at least 250 ft back from the stop line on each intersection leg
