One segment of a Class I two-lane highway is on rolling terrain and has an hourly volume of 950 veh/h (total for both directions), a directional traffic split of 70/30, and PHF = 0.85, and the traffic stream contains 6% large trucks, 3% buses, and 6% recreational vehicles. The two-lane highway segment has the following additional characteristics: 10-ft lanes, 2-ft shoulders, access frequency of 12 per mile, 60% no-passing zones, and a base FFS of 55 mi/h. For these conditions, determine: (1) The analysis direction [1] and opposing direction [2] flow rates for ATS and PTSF.
