Calculate the ESAL.
Q2 / Find the number of lane for the design roadway given the following traffic data:
ADT = 7651 vehicles/hour in both direction, - 2% grade , K = 12% , D= 55% , Truck
30%, Busses = 10% , Normal growth for design period = 30% , Generated growth =
20%, Development traffic = 250% , Track = 2 PCU , Busses = 3 PCU and Ideal
Сараcity
= 1300 PCU / hour / lane.

TXDOT is working on the design of I-69 north of Victoria. They project a demand volume of 52,000 vehicles per day with a K factor of 0.12 and a directional distribution of 56/44 in level terrain with a target LOS of B and 17% trucks and buses. They plan to have roughly one diamond interchange every 2 miles. What number of lanes is required to achieve these design requirements?
