Transportation Services Index
Monthly data, seasonally adjusted
The Transportation Services Index (TSI) is a measure of the month-to-month changes in the output of services provided by the for-hire transportation industry. The index can be examined together with other economic indicators to produce a better understanding of the current and future course of the economy.
|Transportation Services Index||Mar-13||Apr-13|
|Combined (Index: 2000 = 100)||114.66||113.70|
|Percent change from previous month||+ 0.6%||- 0.8%|
|Freight (Index: 2000 = 100)||113.78||112.40|
|Percent change from previous month||+ 0.6%||- 1.2%|
|Passenger (Index: 2000 = 100)||116.83||116.94|
|Percent change from previous month||+ 0.7%||+ 0.1%|
NOTES: TSI is updated monthly with the index numbers for the latest four months considered to be preliminary. With the release of the preliminary number for the latest month, BTS also replaces the number for the oldest preliminary month with a revised number.
With the April 2013 release of the TSI, BTS improved procedures and refined the TSI methodology. As a result, data back through January 2000 have been revised. Documentation will be made available in the near future.
