The Transportation Services Index (TSI) is a measure of the month-to-month change 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||May-07||Jun-07|
|Total Transportation Services Index (2000=100)||110.8||110.0|
|Freight Transportation Services Index (2000=100)||109.7||108.9|
|Passenger Transportation Services Index (2000=100)||115.5||114.7|
NOTE: TSI is updated monthly with the latest four months' index numbers considered preliminary. Each month BTS releases the latest preliminary TSI, and replaces the oldest preliminary TSI with a revised TSI.
