Traffic flow on a section of a two-lane highway can be described by the Greenshields model, with a mean free speed of 54 mi/h and a jam density of 146 veh/mi/In. At the time when the flow was 90 percent of the capacity of the highway, a large dump truck loaded with heavy industrial machinery from an adjacent construction site joins the traffic stream and travels at a speed of 11 mi/h for a length of 3.5 mi along the upgrade before turning off onto a dump site. Due to the relatively high flow in the opposite direction, it is impossible for any car to pass the truck. Determine how many vehicles will be in the platoon behind the truck by the time the truck leaves the highway. vehicles Need Help? Read It Watch It
