- A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?A freeway is to be designed to provide LOS C for the following conditions: design hourly volume of 5600 veh/h; PHF: 0.92; trucks: 6%; free flow speed: 70 mi/h; no lateral obstructions;rolling terrain; total ramp density of 0.75 ramps per mile.Determine: whether eight (four in each direction) 12 ft lanesare enough to provide LOS C.A multi-lane Minor Arterial is being designed through a rolling urban area. The current daily volume = 10000 vpd in both directions with 10% Trucks, peak hourly factor 94%and a 60% directional distribution factor. How many lanes are required?

- A four-lane basic freeway segment on level terrain is being redesigned. The current roadway has 12 ft lanes with 4 ft shoulders. The proposed alignment would expand to six 11-ft lanes with 2 ft shoulders. The road carries 3000 vehicles in the peak hour in one direction, with 925 coming in the peak 15 minutes. The truck mix is 70/30 and makes up 10% of traffic. What is the density and LOS (level of service) before and after the proposed change?An existing urban freeway with 4 lanes in each direction has the following characteristics.
