Question
Determine the operational service level of a basic highway segment
with the characteristics presented below. Assume ideal
conditions of lane width, slope, and clear side clearance.
AADT = 108,920 vpd
• 8 lane highway
Traffic composition: 6% trucks, 1% buses and 1% RVs
Level ground
PHF 0.89
AADT share in peak hour (K factor) = 0.11
Directional distribution of the AADT in the peak hour (factor D) = 65/35
