- |-90 crosses the Snoqualmie River at about milepost 47.5. Here, the eastbound portion of the Interstate has the following characteristics: • Rural freeway classification • No HOV lanes • 12 ft lane width • 10 ft right-side shoulders • 4 lanes (there are 3 lanes going westbound for a total of 7 lanes) • 0.80 interchanges per mile • Volume = 2,800 vehicles/hour • Peak hour factor 0.98 • 18% trucks and buses • 2% recreational vehicles • 4% upgrade for 0.80 miles • Driver population %3D adjustment factor = 1.0.

- Using the suitable diagram, sketch the road elements that typical been constructed. RIGHT-OF-WAY (ROW) Shoulder Cre Taveas Medan Embankment Dsh Divided Rural Highwayarrow_forwardA new basic freeway segment will have 3 lanes in each direction. The left and center lane each has a width of 12 ft while the width of the right lane is 13 ft. The left shoulder is 4 ft while the right shoulder is also 4 ft. There are 2 interchanges within 6 miles (3 miles upstream and 3 miles down stream).The site has level terrain, the design speed is 80 mph the hourly design volume is 5250 veh/h, which includes 9.0% trucks and buses. The peak hour factor is 0.870. Calculate FHV, VP, FFS, LOS Show all workarrow_forwardA 3.25-mile segment of undivided, four-lane highway is primarily on level terrain. The highway segment does, however, contain one sustained grade of 2.5% that is 3,200 ft long. Other relevant information include: Base free-flow speed = 65 mph %3! 11-ft lanes • 4 ft clearance at the roadside (right side) • 20 access points/mile Peak-hour volume = 1,900 veh/h 13% trucks; 2% RVs • PHF = 0.90 • Familiar facility users At what LOS is the highway expected to operate? (Hint: Three different analyses will be needed: a) the level terrain portion of the highway, b) the 2.5% upgrade portion of the highway, and c) the 2.5% downgrade portion of the highway.)arrow_forward
