Determine the value of PTSF for a 6-mile two-lane highway in rolling terrain. Traffic data are as follows: • Volume = 1600 veh/h (two-way) • Percent trucks = 14% • Percent RVs = 4% • Peak hour factor = 0.95 • Percent directional split = 50 - 50 • Percent no-passing zones = 50
True or False: Directional and lane distribution factors need to be considered to obtain initial traffic on the design lane.
