Key: CFS = Commodity Flow Survey; CL = confidence limit; DOT = Department of Transportation; NHTS = National Household Travel Survey; NYS = New York State; RV = recreational vehicle; VIUS = Vehicle Inventory and Use Survey; VMT = vehicle-miles of travel.

Notes:

a. Assume 95% upper CL estimate of NHTS01 personal VMT.

b. NHTS01/VIUS97 ratios for personal travel for pickup, nonpickup used to grow 2001 commercial component of (VIUS stratum 1,2).

c. Assume VMT contribution of non-NYS pickup + panel/van to be at least equal to NYS value.

d. Assume that VIUS97 stratum 3-4 vehicles are illogical as personal transportation choice and are considered commercial use.

e. Assume VIUS97 heavy-truck VMT estimate for surrounding states is equal to NYS estimate, since CFS shows 70% of all NYS origin movements are less than 50 miles; add to this the Reebie TranSearch 2001 primary truck shipment assigned network VMT in NYS with equal empty backhaul estimate (no estimate for secondary and/or transshipments are then made).

f. NYSDOT operating assistance-based bus transit VMT (000,000), which assumes 10% addition for deadhead miles 257.9

g. NYS school bus VMT (000,000) 204.8

h. Census provisions for state-based relative error computation are not provided. U.S. error is significantly less than that for the NYS sample. Twice the value of the U.S. relative error for truck-miles by operating class were used for NYS tables of annual miles by opclas and samtyp to compute upper 95% CL estimate.

i. Total includes 14.2 million VMT for RV not included in any of the other table rows.
