Question: A 2 . 4 - mile segment of a Class I two - lane highway on level terrain has an average free - flow speed

A 2.4-mile segment of a Class I two-lane highway on level terrain has an average free-flow speed measured at 49 mph, while two-way flow was measured at 190 vph. During the peak hour, 340 vehicles were counted in the analysis direction, 155 vehicles were counted in the opposing direction, and PHF was found to be 0.82. There are 6% trucks and 2% RVs. If this segment operates at LOS D, what proportion of this segment has no passing zones?
