Abstract

The 1950 HCM [1] recognized the critical interaction between directional flows on a two-lane, two-way rural highway. Because of this, in 1950 and 1965, the models for two-lane highways dealt with both directions simultaneously. In 1950, it was argued that to keep a single lane in one direction fully utilized, that passing opportunities had to be unrestricted by alignment, sight distance, or the existence of flow in the opposite direction. Since the basic capacity of a lane on a multilane facility had been established as 2,000 pc/h/ln, it was argued that this could be achieved on a two-lane highway only when there was no opposing flow to inhibit passing.
