A = January 1 registration mix from Table 2.2.4.
B = Fleet sales fractions
D * Sales weighted fleet mileage accumulation rate from Table 2.2.4,
adjusted to January 1
0(1) » Annual Mi les(l)
D(MYI)= .25*(Annual Miles(MYI)) + .75*(Annual Mi 1 es (MY I - 1)) , MY I =2, . . ., 20+
NOTE : In general, the travel weighting fractions will change for every
calendar year since the sales fraction (column B) changes
for almost every model year.

NOTE : The fractions given in this table are used in the calculation of the
operating-mode/ temperature correction factor (OMTCF).
WHERE : OMTCF = ((TERM1 + TERM2 -I- TERM3)/DENOM)
TERM1 = W *TCF (1)*(B1+D1*M)
TERM2 = (l-W-X)ftTCF (2) * (B2+D2*M)
TERM3 = X *TCF (3)*(B3+D3*M)
DENOM = BO + DO*M
W = Fraction of VMT in the cold start mode
X = Fraction of VMT in the hot start mode
TCF (b) = Temperature correction factor for pollutant, model
year; for test segment b
M = Cumulative mileage / 10,000
