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.)
