- 4. 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? What LOS would occur for a typical 4-lane rural interstate design? DHV = AADT * K * D DHV – design hourly volume AADT - average annual daily traffic K- peak hour adjustment factor D- directional distribution (make design conservative)How would you describe the following with reference to the Ghana Highway Authority (GHA) Design Guide?i) The relationship between design speed and functional classification ii) The difference between the design speeds and the absolute speed valuesB- How many classes of highways may be identified in the Figure. listed it according to the No. shows in the Figure. 2 4 5 8
