Table 5-2. Summary of vehicle emission factors measured at Ft. Bliss and Comparison
with emission factors calculated as specified in AP-42 (USEPA, 1999) for two
values of silt content (4% and 7%); moisture content was assumed to be 0.2%. The
speed dependence of the measured emission factors is given in the third column and
represents the slope of a linear regression between measured emission factor (g/vkt)
and vehicle speed (mph); the R 2 value for the regression is given in the fourth
column. For cases where a particular vehicle was tested more than once, the average
of the two tests is used. All emission factors are reported in grams per vehicle
kilometer traveled (g/vkt). ..................................................................................... 5-19
