Rh 1937, total, for the entire system, 5,823,745 vehicle-miles per day. In table 2, this figure is shown as the sum of the average daily vehicle-mileage on each of 75 sections into which the entire system is divided. The table shows the length of each section and the estimated average number of vehicles that would have used it, in addition to the utilization expressed in vehicle-miles. The sections are arranged in the descending order of estimated average daily traffic and the sectional lengths and estimated vehicle-mileages are progressively accumulated in that order. For each accumulation of length and vehicle-mileage a corresponding average daily volume of traffic is shown in the last column of the table.
