WebIn the HCM, on-ramp analysis is more often associated with Freeway Merge segments. However, one case covered by the HCM6 (p. 14-30) deals with lane additions or drops for merges and diverges respectively. In these cases, the Merge segment should be treated as a Basic Freeway segment with the appropriate number of lanes.
