Monthly data, not seasonally adjusted
Load factor measures usage by capacity. It is calculated by dividing passenger miles (the aggregation of trip lengths for individual passengers) by seat miles (the sum of the products of total seats available and total miles traveled for individual trains).
|Average Rail Passenger Load Factor||Aug-08||Aug-09|
|Passenger load factor (percent)||58.8||55.7|
|Percent change from same month previous year||5.57||-5.27|
NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
