A particular roadway segment has a 6000-ft section of 3% upgrade, followed by a 5000-ft section of 5% upgrade. The traffic on the road includes 8% trucks and 4% recreational vehicles. Determine the PCEs.
None
A basic segment of a rural freeway has the following characteristics:
• Four-lanes (two lanes in each direction)%3B
There is one ramp within 3 miles upstream, and 2 ramps within 3 miles downstream;
10-ft lanes;
Right shoulder width of 4 ft;
• Level terrain;.
10% trucks and 5% buses in the vehicle stream.
Calculate the FFS at this freeway section and then determine the level of service (LOS) when the
flow rate is 1740 pc/h/In.
(Write the answer for the LOS in the box below).

- A 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 long segment of suburban freeway is to be designed on level terrain. The level segment, however, is followed by a 4.5% grade, 2.0 miles in length. If the DDHV is 2,500 vehicles per hour with 15% trucks (standard mix), how many lanes will be needed on the (A.) Upgrade, (B.) Downgrade, (C.) Level terrain segment to provide for level of service C? Lane widths and lateral clearances may be assumed to be 12 feet and 6 feet, respectively. Ramp density is expected to be 1.0 ramps per mile. The PHF is 0.92. Good weather, no incidents, no work zones, and regular users of the facility may be assumed.arrow_forwardAn urban freeway presently has three 12-ft lanes on a 3 percent upgrade 1.75 mi long. The traffic includes 8 percent trucks and buses (recreational vehicles are negligible). There are no lateral obstructions. Design speed is 70 MPH. (a) What is the present capacity of the upgrade? (b) How much could the capacity be increased by widening and remarking the existing traveled way to provide four 10-ft lanes up the grade?arrow_forward
