NOTES: The combined TSI measures the movement of both freight and passengers. The Freight TSI measures just the movement of freight and includes for-hire trucking (parcel services are not included), freight railroad services (including rail-based intermodal shipments such as containers on flat cars), inland waterway traffic, pipeline movements (including principally petroleum and petroleum products and natural gas), and air freight. The Passenger TSI measures the volume of passengers and consists of local mass transit, intercity passenger rail, and passenger air transportation.
The TSI is updated monthly with the index numbers for the latest four months considered to be preliminary. 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.
