ii. Total Number of Commercial Vehicles per direction, Vc

Where r = traffic growth rate
x = Design life

iii. Total Equivalent Standard Axles, ESA

ESA = Vc x e

Where, e = equivalent factor (Refer Table 3.1 in (Arahan Teknik (Jalan) 5/85 or e = 2.52)

iv. Daily Traffic Flow at the end of the design period, Vx

V x = V 1 (1 + r) Where V1 = AADT / 2 (per direction)
x

v. Capacity Estimation

Maximum Hourly Capacity, c

c = I x R x T

Where I = Ideal hourly capacity (Refer Table 3.2 in (Arahan Teknik (Jalan) 5/85)
R = Roadway Reduction Factor (Refer Table 3.3 in (Arahan Teknik (Jalan) 5/85)
T = Traffic Reduction Factor (Refer Table 3.4 in (Arahan Teknik (Jalan) 5/85)

vi. Daily Capacity, C

C = 10 x c

Note: Assume c is 10% of C
