Problem 2 (20 Points) A new rural freeway is to be designed in Kentucky to carry a peak-aftemoon directional design volume of 1,500 veh/hr on a 4 percent upgrade along a 2-mile stretch. The distribution of the 1,500 vehicles (in 15-minute increments) during the afternoon peak (4:30 to 5:30 pm) is as follows: Time period Traffic or vehicular counts 4:30 to 4:45 pm 300 4:45 to 5:00 pm 400 5:00 to 5:15 pm 450 5:15 to 5:30 pm 350 The expected free-flow speed (FFS) is 65 mi/hr and the expected traffic mix is 90 percent passenger cars and 10 percent heavy vehicles (1.e., trucks, buses, and RVs). Assume 50% SUTs to 50% TTs. Determine the total number of required lanes on that rural freeway to operate with at least LOS C during the peak afternoon hour. Solution
