6.25 A four-lane freeway (two lanes in each direction) segment consists of passenger cars only, a driving population of regular users, a peak-hour directional distribution of 0.70, a peak-hour factor of 0.80, and a measured free-flow speed of 70 mi/h. Assuming Fig. 6.7 applies, if the AADT is 30,000 veh/day, determine the level of service for the 10th, 50th, and 100th highest annual hourly volumes.
