Design Procedure:
Calculate Initial Annual Comercial Vehicle Traffic per direction, Vo
Where
AADT = average annual daily traffic (veh/day) in both direction
Pc = percentage of commercial vehicles
D = Directional distribution (0.50 if directional split is 50:50)
L = Lane distribution (1.00 if single lane)
Total Number of Commercial Vehicles per direction, Vc
Where r = traffic growth rate
x = Design life
