A segment of four-lane freeway (two lanes in each direction) has a 3% upgrade that is 450 m long followed by a 300-m 4% upgrade. It has 3.6 m lanes and 0.9 m shoulders. The directional hourly traffic flow is 2000 vehicles with 5% large trucks and buses (no recreational vehicles). The total ramp density for this freeway segment is 1.45 ramps per kilometer. If the peak hour factor is 0.9 and all of the drivers are regular users, what is the level of service of this compound grade freeway segment?

An eight-lane freeway (four lanes in each direction) is on rolling terrain and has 11-ft lanes with a 4-ft right-side shoulder. The total ramp density is 1.5 ramps per mile. The directional peak-hour traffic volume is 5400 vehicles with 11% heavy vehicles. The peak-hour factor is 0.95. It has been decided that heavy vehicles will be banned from the freeway during the peak hour. What will the freeway’s density and level of service ben before and after the ban? (Assume...

A six- lane freeway (three lanes in each direction) in a scenic area has a measured free- flow speed of 55 mi/ h. The peak- hour factor is 0.80, and there are 7% SUTs and 3% TTs in the traffic stream. One upgrade is 4.5% and 1.5 mi long. Free-flow speed is 70 mph. If the peak- hour traffic volume is 3900 vehicles, determine level of service?

A freeway segment has the following characteristics: 3 lanes in each direction Lane width = 11 ft Right shoulder width (lateral clearance) = 4 ft There is 1 interchange within 3 miles downstream, and 2 interchanges within 3 miles upstream. The freeway is located on a level terrain and has 10% of heavy vehicles in the traffic stream. Calculate the free-flow speed (FFS) for this freeway segment using the HCM formula (FFS = 75.4 – fLW – fLC – 3.22TRD0.84).

A northbound two-lane (one direction) segment of freeway currently has a measured density of 32.0 pc/mi/ln and a measured FFS of 65 mi/h. The peak-hour factor is 0.95, the traffic stream contains 7% single-unit trucks and 3% tractor-trailer trucks. The freeway segment is on a 3.5% upgrade that is ¾ of a mile long. With the peak-hour factor unchanged, how many trucks (assuming the same ST/TT split) can be added to the peak hour before capacity is reached?

A long segment of the 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 veh/h with 15% trucks (standard mix), how many lanes will be needed on the (a) upgrade, (b) downgrade, (c) level terrain segment to provide for the level of service C? Lane widths and lateral clearances may be assumed to be 12 ft and 6 ft, respectively. Ramp...
