The March 2005 release of the Transportation Services Index (TSI), an economic measure of freight and passenger movements, marked the Bureau of Transportation Statistics (BTS) entry into the company of federal statistical agencies that produce monthly U.S. economic indicators. The TSI consists of three component indexes: a freight index, a passenger index, and a combined (or total) index. Figure 1 shows the freight and passenger indexes as recently displayed on the BTS website. The TSI is the broadest monthly measure of U.S. domestic transportation services and, as such, provides the best current measure available of these services. As an index, the TSI reflects real monthly changes in freight and passenger services in the United States.
