2. A section of rural freeway normally operates at a capacity of 2400 pc/h/ln. A crash reduces the capacity to zero for a period of 10 minutes, resulting in significant queue spillback. Once the crash has been cleared, the freeway operates at a lower capacity of 1200 pc/h/ln for 5 minutes, before returning to the full operational capacity (2400 pc/h/ln). During this entire period, vehicles continue to arrive at a constant rate of 1800 pc/h/ln. Assuming D/D/1 queuing, determine the following (be careful of units): a. How long will it take for the resulting queue to clear? (6 points) b. How much total delay is experienced? (6 points) C. What is the average delay per vehicle during the period over which queuing occurs? (4 points) d. What is the average queue length during the period over which queuing occurs? (4 points)
