NOTES:  Only trips in which the transportation mode and trip purpose could be identified are included. On this table, differences are measured in columns instead of rows.  The difference between shaded cells in the same column are not statistically significant, except for Business where Train is different from Other; Commute where Air is different from Bus and Other, Personal Business where Air and Bus are different from Train and Other, and for Other trip purposes where Air is different from Bus and Train. Underlined estimates are based on a small sample size (<30) or a coefficient of variation greater than 30% and are not reliable.",,,,,,,,,,,,,
