The Transportation Satellite Accounts (TSAs) belong to the group of satellite industry accounts that supplement national income and product accounts and input-output accounts by focusing on a particular aspect of economic activity. The TSAs seek to capture transportation services provided by both for-hire transportation industries and by nontransportation industries for their own use, and transportation by households through the use of personal vehicles.

For-hire transportation consists of the air, rail, truck, passenger and ground transportation, pipeline, and other support services (e.g., air traffic control) provided by transportation firms to industries and the public on a fee-basis, such as railroads, transit agencies, common carrier trucking companies, and pipelines.

In-house transportation consists of air, rail, water, and truck services provided by businesses for their own use. Business in-house transportation includes privately owned and operated vehicles of all body types, used primarily on public rights of way, and the supportive services to store, maintain, and operate those vehicles. A baker’s delivery truck is an example of business in-house transportation.

Household transportation covers transportation provided by households for their own use through the use of a motor vehicle. Air passenger travel is included in for-hire air transportation.
