Maintaining Level of Service C on a Freeway. A four-lane freeway is located on rolling rural terrain and has two 12-ft lanes in each direction and no lateral obstructions within 8 ft of the right-hand lane. The traffic stream consists of cars and trucks. A peak-hour volume of 3600 vehicles is observed in the major direction, with 1000 arriving in the most congested 15-min period. TRD = 0.24 ramps/mi. If any data are missing, adopt default values. A. What is the PHF?
B. What is the density of the peak hour traffic? At what level of service is the freeway operating?
C. If a level of service no worse than C is desired, how many lanes are needed in each direction?
