Table B12 Distribution of Pre- and Post-9/11 Long-Distance Trips by Mode, for Each Trip Distance
Percentage trips (standard error)
NOTE: Cells with a small sample size (< 30) or that have a covariance or c.v. (> 0.3) are shaded dark grey to indicate that the weighted estimates are not reliable. Cells with bold type indicate significant differences (p<0.05) between pre-9/11 and post-9/11 estimates.
