- 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)The DDHV fora given highway project is 2200 veh/h and the design capacity is 1450 veh/h/ln. The calculated number of lanes in this case is aboutA section of a two-lane rural highway is expected to have the following characteristics: Design speed of 80 km/hr, lanes of 3.6 m, walks of 1.2 m, mountainous terrain, 70% of sections without passing distance and length of 7 km.
