TXDOT is working on the design of l-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?

Question

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)

Consider the problem of traffic flow on a three-lane (one direction) freeway which can be described by the Greenshields model. One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take several hours. It is estimated that the capacity at the work zone will be reduced by 30 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 60 mi/h and the jam density is 130 veh/mi/ln. It is estimated that the demand flow on the highway during the emergency repairs is 86 percent of the capacity. Using the deterministic approach, determine the following for the expected repair periods of 1 h, 1.5 h, 2.5 h, 2.75 h, and 3 h.
