Table 7: Percent of Long-Distance Trips Using the Same Going and Returning Mode

Excel | CSV

Travel via long-distance mode (both directions) Trips via same mode in each direction (percent) Standard error
Personal vehicle 99.3 0.00
Air 94.1 0.01
Bus 90.4 0.02
Train 83.3 0.05
Other 72.7 0.10
Total 98.5 0.00
Total for public transportation modes 92.1 0.01

NOTES: Only trips in which the transportation mode could be identified in both travel directions are considered.

On this table, differences are measured in columns instead of rows. There is no statistical difference between the percentage of air and bus trips that return via the same mode. There is also no statistical difference between the percentage of bus, train and other mode trips that return via the same mode.

Underlined estimates are based on a small sample size (<30) or a coefficient of variation greater than 30% and are not reliable.
