NOTES: Only trips in
which the transportation mode could be identified in both travel directions
are considered.
The only statistical difference in the percentage of return
trips utilizing personal vehicle is between air and "other" and
between bus and "other". All
other comparisons in that column are not statistically different.
Underlined
estimates are based on a small sample size (<30) or a coefficient of
variation greater than 30% and are not reliable.
