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 that the heavy vehicles are removed and all other traffic attributes are unchanged.)

A westbound section of freeway currently has three 12-ft wide lanes, a 6-ft right shoulder, and no ramps within 3 miles upstream and downstream of the segment midpoint. It is on rolling terrain with 10% heavy vehicles and is operating at capacity with a peak-hour factor of 0.900. If the road is expanded to four 11-ft lanes with a 2-ft right shoulder, and traffic after the expansion is projected to increase by 10% with the same heavy vehicle percentage and...

A six-lane freeway is being designed for a location in rolling terrain. The expected free- flow speed is 65 mph. Lane widths will be 12 ft and right shoulder widths will be 6 ft. During the peak hour, it is expected there will be a directional peak- hour volume of 2700 vehicles with 12% heavy vehicles in the traffic stream. The PHF is expected to be 0.90. 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).
