A segment of four-lane freeway (two lanes in each direction) has a 3% upgrade that is 1500 ft long followed by a 1000-ft 4% upgrade. It has 12-ft lanes and 3-ft shoulders. The directional hourly traffic flow is 2000 vehicles with 3% SUTs and 3% TTs. The total ramp density for this freeway segment is 2.33 ramps per mile. if the peak-hour factor is 0.90, 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 four-lane freeway with two lanes in each direction has a measured free-flow speed of 55 mi/hr. The peak-hour factor is 0.80 and there are 6% trucks, 2% buses, and 2% recreational vehicles in the traffic stream. One upgrade is 5% and 0.5 miles long. A traffic engineer has determined that the freeway is operating at capacity on this upgrade during the peak hour. If the peak-hour traffic volume is 3900 vehicles, what value for the driver population adjustment factor...

Determine the level of service for the following freeway segment: 6 total lanes (in both directions), rolling terrain, 11' lanes, obstructions 2' from the right of the travel lane, 1.5 diamond interchanges per mile, commuter traffic. There are 15% large trucks and 15% RVs. The directional hourly volume is 2200 vehicles/hour. The peak hour factor is 0.70

A six-lane multilane highway (three lanes in each direction) has a peak-hour factor of 0.90, 11-ft lanes with a 4-ft right side shoulder, and a two-way left-turn lane in the median. The directional peak-hour traffic flow is 4000 vehicles, and the traffic stream has 5% single-unit trucks and 5% tractor-trailers. What will the level of service of this highway be on a 2.5% upgrade that is 1.5 miles long if the speed limit is 55 mph and there are 15...

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 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 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?
