Figure 4-1. Value Added by Freight Transportation to GDP by Transportation Mode: 1992 and 1996 (Billions of Dollars)
Freight transportation is a big part of the economy. The value generated by transportation services in moving goods and people on the transportation system is about 5 percent of GDP. In the transportation services sector about 60 percent of the value is generated by for-hire transportation services and the rest is generated by “in-house” transportation (transportation provided by businesses for their own use). In-house trucking accounted for $142 billion of GDP in 1996 (the latest year for which data are available) and for-hire trucking accounted for $101 billion.
