NOTES: Only trips for which transportation mode and household income can be determined are tabulated.
Column totals may not add to 100 percent due to rounding.
Underlined estimates are based on a small sample size (<30) or a coefficient of variation greater than 30% and are not reliable.
Percentages for shaded cells on the same row are not statistically different, except for the following comparisons: Bus, $25K-$49K and $75K+; Other, $25K-$49K and $75K+, $50K-$74K and $75K+. It should be noted that for "other" modes, all categories except $50K-$74K are based on a sample size that is too small to provide a reliable estimate.
