Question 3 (20 points): The traffic volume on a 2-lane highway is 1600 veh/hr in each direction
Page 3 of 6
with a density of 20 veh/mi. A large dump truck enters the traffic stream from an adjacent
construction site at 20 mph and carries on this way for 2 miles before turning off to the dump
site. Because flow is so high in the opposite direction, no one can pass the truck. As a result,
traffic back up behind the truck at four times the density (i.e., 4x20 = 80 veh/mi) at a volume of
1000 veh/hr. How many vehicles get caught in the traffic congestion before the truck exits the
highway?
How can construction project managers find a balance between speeding up schedules and the risks of making more mistakes and needing rework, especially when using methods like fast tracking?
Help i keep getting the wrong answer. So I must be doing something wrong.
