A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 4-ft shoulders, and there are three ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has only regular users, there are 8% large trucks and buses (no recreational vehicles), and it is on rolling terrain with a peak-hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6. What is the freeway's AADT?

Question
A four-lane freeway (two lanes in each direction)
operates at capacity during the peak hour. It has
11-ft lanes, 4-ft shoulders, and there are three
ramps within three miles upstream of the
segment midpoint and four ramps within three
miles downstream of the segment midpoint. The
freeway has only regular users, there are 8% large
trucks and buses (no recreational vehicles), and it
is on rolling terrain with a peak-hour factor of
0.85. It is known that 12% of the AADT occurs in
the peak hour and that the directional factor is
0.6. What is the freeway's AADT?
