The number of vehicles arriving at the upstream of a freeway bottleneck (free of queues) is shown in the table below. Based on the numbers given in the table, determine: (1) Bottleneck capacity in vehicles per hour (vph) (2) Downstream measured flow rate in the third time interval (3) The demand during the third time interval (4) Queue length at the end of the third and fourth intervals
