Problem 2 A traffic engineer needs to determine the AADT on

Problem 2: A traffic engineer needs to determine the AADT on a rural primary road that has the volume distribution characteristics shown in the previous tables. The following volume data were collected on a Wednesday during April. Determine the AADT of the road. Given: Wednesday in April ·1 :00-2:00 pm 600 veh ° 2:00-3:00 pm 330 veh ° 3:00-4:00 pm 456 veh ° 4:00-5:00 pm 787 veh Find: AADT

Solution

Solution:-

Given

1 – 2 pm           -   600 vehicle

2 – 3 pm            - 330 vehicle

3 – 4 pm           - 456   vehicle

4 – 5 pm            -    787     vehicle

Average of traffic = ( 600 + 330 + 456 + 787 )/4

Average of traffic = 544 vehicles

12 hours flow = 12 * 544 = 6528 vehicles

AADT of road for 24 hours = (12 hours flow ) * F₃ * F₄

AADT of road for 24 hours = 6528 * 1.231 * 0.947

AADT of road for 24 hours = 7610 vehicles Answer
