The U.S. Department of Transportation’s Bureau of Transportation Statistics and Volpe National Transportation Systems Center on Dec. 16 released its 50th anniversary edition of National Transportation Statistics (NTS).
First published in 1971, NTS has grown to more than 200 data tables.
The wide-ranging data span the U.S. transportation system’s infrastructure for multiple modes, safety record, energy use, environmental impacts, and economic performance.
One notable finding on economic performance: From 1999 to 2018, inflation-adjusted rates of revenue per ton-mile increased 27% for truck, rose 25% for Class I railroad, and rose 16% for domestic water transportation.
Over the past three decades (from 1990 to 2019), the average length of haul has remained relatively constant for inland waterway shipments, but has increased over 40% for Class I railroads.
