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 industries. 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-05||Apr-05|
|Total Transportation Services Index (2000=100)||111.6||111.7|
|Freight Transportation Services Index (2000=100)||112.5||112.6|
|Passenger Transportation Services Index (2000=100)||109.2||109.3|
NOTE: The index numbers for the latest three months are considered to be preliminary. BTS releases the preliminary number for the latest month and replaces the number for the oldest preliminary month with a revised number. All other revisions are held until an annual comprehensive revision of the TSI, which will be released as part of the following June TSI release.
