1) A 6-lane two-way arterial road has a maximum flow of 6,000 vehicles per hour on one direction. It is operating at 3,600 vehicles per hour at time, t=0. A collision occurs, blocking the two lanes, and restricting the flow of the outermostlane to 1,600 vehicles per hour. After 40minutes, the police have cleared the middlelane from accident debris; the operating volume at that time increased to 2,400 vehicles per hour.20 minutes past, the innermost lane was finally cleared of the accident. Traffic returns to normalas soon as the queue has already immoderate. a.Determine the maximum length of queue that occurred.
