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 400 large trucks and 6% buses. The peak- hour factor is 0.92. It has been decided that large trucks will be banned from the freeway during the peak hour. How much will the ban reduce expected traffic density and the level...
