You were driving along I-10 and at t=0 saw a crash ahead that blocked all the lanes. Your vehicle was the last one to join the queue. The police at the scene closed the freeway behind you and diverted all the traffic so no other vehicle could join the queue behind you. You made a count and found that the queue had 154 vehicles (including your vehicle). At t=9 minutes, the police opened one lane to allow vehicles in the queue to discharge at =20 veh/minute. Assume D/D/1 queuing. Draw the cumulative arrival and departure curves. Clearly state next to the curves the arrival or departure rates. Calculate the time (T) when you leave the accident scene. Calculate the total delay experienced by these 154 vehicles.
