a segment of freeway consists of two upgrades of 2%, 800 m long and 3% 600 m long. Determine the PCE trucks/buses and recreational vehicles on this composite upgrade if 6% of vehicles are truck and 10% are recreational vehicles. Determine the number of lanes required for a freeway section if the section is to operate at LOS C. The input parameters include: One Cloverleaf interchange per mile (ramp density = 4 ramps/mile or 2.5 ramps/km) lane width = 12 fr (3.6m) right-side lateral clearance = 6years (1.8m) traffic composition: 10% trucks, 2% RVs V = 3000 veg/h Number of lanes: Must be greater than or equal to 2 Pero direction PHF = 0.95 Analysis segment is (0.35 miles (0.56km)) long with 4.5 % grade

Question
a segment of freeway consists of two upgrades of 2%, 800 m long and 3% 600 m long. Determine the PCE trucks/buses and recreational vehicles on this composite upgrade if 6% of vehicles are truck and 10% are recreational vehicles.
Determine the number of lanes required for a freeway section if the section is to operate at LOS C. The input parameters include:
One Cloverleaf interchange per mile (ramp density = 4 ramps/mile or 2.5 ramps/km)
lane width = 12 fr (3.6m)
right-side lateral clearance = 6years (1.8m)
traffic composition: 10% trucks, 2% RVs
V = 3000 veg/h
Number of lanes: Must be greater than or equal to 2 Pero direction
PHF = 0.95
Analysis segment is (0.35 miles (0.56km)) long with 4.5 % grade
