KEY: - = Zero or Less than half the unit shown; thus, it has been rounded to zero.
1 Shipments are grouped into distance categories based on
Great Circle Distance (GCD). GCD is the shortest distance between 2 points on
the surface of a sphere over the surface of that sphere.
2 Ton-miles estimates are based on estimated distances traveled along a
modeled transportation network.
NOTES: Value-of-shipments estimates are reported in current prices. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
