Wednesday, April 9, 2008 - The Freight Transportation Services Index (TSI) was unchanged in February from January, following a 2.4 percent monthly increase in January, the U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today (Table 1).

Since dropping to a recent low in September, the freight index has increased in three months, declined in one month and has been unchanged in one month (Table 2).  At 111.5, the freight TSI is down 1.5 percent from its peak of 113.1 achieved in November 2005 but up 3.2 percent in the five months since its recent low of 108.0 in September 2007. For additional historical data, go to http://www.bts.gov/xml/tsi/src/index.xml.

The 2.4 percent increase in the freight index since December was the largest in the first two months of the year in at least a decade. It was the first December to February increase since 2005 (Table 3).

The freight TSI measures the month-to-month changes in the output of services provided by the for-hire freight transportation industries. The index consists of data from for-hire trucking, rail, inland waterways, pipelines and air freight.

The February freight TSI level of 111.5 was 2.7 percent higher than the February 2007 level. The index is 1.1 percent above the February 2006 level but 0.4 percent lower than the February 2005 level (Table 4).  

Despite declines from recent February levels, the freight index has increased 9.2 percent in five years and 13.7 percent in 10 years (Table 5).

The TSI is a seasonally adjusted index that measures changes from the monthly average of the base year of 2000. It includes historic data from 1990 to the present. Release of the March index is scheduled for May 14.

BTS has issued a new technical report explaining the TSI. BTS Technical Report: Transportation Services Index and the Economy is available for download at https://www.bts.gov/pdc/index.xml in the BTS bookstore.

Transportation Services Index for Passengers

The TSI for passengers fell 1.2 percent in February from its January level, falling for the second consecutive month (Table 6). The Passenger TSI February 2008 level of 114.1 was 2.1 percent higher than the February 2007 level, marking six consecutive annual increases since February 2003 (Table 7). With the February decline, the passenger index fell for the first two months of the year for the second year in a row (Table 3). However, the passenger index is up 20.1 percent in five years and 25.8 percent in 10 years (Table 5).

The passenger TSI measures the month-to-month changes in the output of services provided by the for-hire passenger transportation industries. The seasonally adjusted index consists of data from air, local transit and intercity rail.

Combined Freight and Passenger Index

The combined freight and passenger TSI fell 0.3 percent in February from its January level, declining after a one-month increase (Table 8). The combined TSI February 2008 level of 111.8 was 2.5 percent higher than the February 2007 level (Table 9). Despite the February decline, the combined index rose for the first two months of the year for the first time since 2005 (Table 3). The combined index is up 11.9 percent in five years and 16.9 percent in 10 years (Table 5).

The combined TSI merges the freight and passenger indexes into a single index.

More on TSI

Note:TSI numbers for October (Freight, Passenger and Combined) were revised because of revisions in the output data of the component transportation services. The October Freight TSI is 109.8, revised from the 109.5 reported in the March release. The October Passenger TSI is 118.2, revised from 116.0. The October Combined TSI is 111.5, revised from 110.7. The TSI for November, December, January and February are preliminary.

TSI revision policy: 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. More information about the monthly revision policy, the 2007 comprehensive revision conducted with the July release and the TSI index is available at http://www.bts.gov/xml/tsi/src/index.xml

Brief Explanation of the TSI

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 TSI tells us how the output of transportation services has increased or decreased from month to month. The index can be examined together with other economic indicators to produce a better understanding of the current and future course of the economy. The movement of the index over time can be compared with other economic measures to understand the relationship of changes in transportation output to changes in Gross Domestic Product (GDP).

The freight transportation index consists of:

For-hire trucking,
Railroad freight services (including rail based intermodal shipments such as containers on flat cars),
Inland waterways transportation,
Pipeline transportation (including principally petroleum and petroleum products and natural gas), and
Air freight.

The index does not include international or coastal waterborne movements, private trucking, courier services, or the US Postal Service.

The passenger transportation index consists of:

Local transit,
Intercity passenger rail, and
Passenger air transportation.

The index does not include intercity bus, sight seeing services, ferry services, taxi service, private automobile usage, or bicycling and other non-motorized transportation.
