Note: The tonnage totals directly related to the state (i.e., leaving/entering/within) are derived from the tonnage origin and destination estimates found in the Freight Analysis Framework (FAF) database. The number for each state's "through" tonnage is estimated by using "through truck FAF vehicle miles traveled (VMT)." The ratio of "through truck FAF VMT" to "leaving/entering/within truck FAF VMT" for each state is then applied to the "leaving/entering/within FAF tonnage" to generate the "through FAF tonnage."

Note: The tonnage totals directly related to the state (i.e., leaving/entering/within) are derived from the tonnage origin and destination estimates found in the Freight Analysis Framework (FAF) database. The number for each state's "through" tonnage is estimated by using "through truck FAF vehicle miles traveled (VMT)." The ratio of "through truck FAF VMT" to "leaving/entering/within truck FAF VMT" for each state is then applied to the "leaving/entering/within FAF tonnage" to generate the "through FAF tonnage."
