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?
You are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS C using the 40th highest annual hourly volume (K = 0.116). A 6 B) 4 c) 10 D) 8

A section of four lane (two lanes in each direction) freeway in mountainous terrain, which is 2.5 mi long, is to be improved to carry on a regular weekday a heavy volume of 3000 veh/h, consisting of 80% passenger cars, 15% trucks, 3% buses, and 2% recreational vehicles. The PHF is 0.90. Determine the additional number of 12-ft lanes required in each direction if the road is to operate at LOS B. The base FFS is 65mph, there is a lateral obstruction 4ft from the pavement on the right side of the road, and interchange spacing is 2 mi. Driver population adjustment factor fp= 1.0.

Demand volume (3452 vehicle per hour) ● ● ● ● ● ● ● 1 Number of lanes (3 lanes in one direction) Width of lanes (11ft per lane) Lateral clearance on the right side of the freeway (4 ft) Total ramp density (2 miles between ramps, or 0.5 ramps per mile) Percent of heavy vehicles (5% trucks/buses and 0% recreational vehicles) Peak hour factor (0.927) I Terrain (level) Driver population factor (familiar drivers)
Traffic volume is 2578 veh/hr with 687 vehicles arriving in peak 15 minutes.There are tow lanes, 12 percent trucks(30/70 split for SUT/TT), the length of the road is 1.8 miles long with a 3.5 percent grade. calculate the analysis flow rate?
