A new rural freeway is to be designed in Kentucky to carry a peak-afternoon directional design volume of 1,500 veh/hr on a 4 percent upgrade along a 2-mile stretch. The distribution of the 1,500 vehicles (in 15-minute increments) during the aftemoon peak (4:30 to 5:30 pm) is as follows: Time period 4:30 to 4:45 pm 4:45 to 5:00 pm 5:00 to 5:15 pm 5:15 to 5:30 pm Traffic or vehicular counts 300 400 450 350

Question
![A new rural freeway is to be designed in Kentucky to carry a peak-aftermoon directional design
volume of 1,500 veh/hr on a 4 percent upgrade along a 2-mile stretch. The distribution of the 1,500
vehicles (in 15-minute increments) during the aftemoon peak (4:30 to 5:30 pm) is as follows:
Time period
4:30 to 4:45 pm
4:45 to 5:00 pm
5:00 to 5:15 pm
5:15 to 5:30 pm
Traffic or vehicular counts
300
400
450
350
The expected free-flow speed (FFS) is 65 mi/hr and the expected traffic mix is 90 percent
passenger cars and 10 percent heavy vehicles (i.e., trucks, buses, and RVs). Assume 50% SUTS to
50% TTs. Determine the total number of required lanes on that rural freeway to operate with at
least LOS C during the peak aftermoon hour.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5c20ae7a-9323-4beb-a994-dae1fa37f72e%2F7a54e003-fb8e-42af-8cdf-eed2a9dd9643%2Fy3cv7he_processed.jpeg&w=3840&q=75)
