A section of Texas Highway 83 (Tx83) has a capacity in the eastbound direction of 4,000 vehicles per hour and a constant flow of 2,900 vehicles per hour during the morning commute. At 7:00am, a traffic accident closes the highway to all traffic (eastbound and westbound). At 7:12am, the highway is partially opened in both directions with a capacity in the eastbound of 2,000 vehicles per hour. Finally, the wreckage is removed, and the highway is restored to full capacity at 7:31am. Determine the total delay (in vehicle minutes) and the longest queue length in vehicles as well as the longest wait of any vehicle (in minutes).
