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?
