Reference no: EM132416479

Problem: An eight lane urban freeway (four lanes in each direction) is on rolling terrain and has 11-ft lanes with a 4-ft right-side shoulder. The interchange density is 1.25 per mile. The base free-flow speed is 70 mi/hr. The directional peak-hour traffic volume is 5400 vehicles with 6% large trucks and 5% buses (no recreational vehicles). The traffic stream consists of regular users and the peak hour factor is 0.95. It has been decided that large trucks will be banned from the freeway during the peak hour. What will the freeway's density and level of service be before and after the ban? (Assume that the trucks are removed and all other traffic attributes are unchanged)
