Table 13 Arithmetic mean, standard deviation, and derived upper thresholds of GIS-based walking time for different levels of satisfaction with neighborhood accessibility (based on accessibility survey, n = 716 respondents)
Rating of neighborhood accessibility | n | GIS-based walking time (min) | Dunnett-T3 sign. level (very good) | Upper threshold (mean walking time + 1 SD) | |
|---|---|---|---|---|---|
Mean | SD | ||||
Very good (1) | 1357 | 5.70 | 3.58 | 9.28 (~ 9 min) | |
Good (2) | 557 | 8.36 | 4.68 | p < 0.001 | 13.04 (~ 13 min) |
Satisfactory (3) | 174 | 10.58 | 5.48 | p < 0.001 | threshold can not be derived from survey data |
Sufficient (4) | 61 | 10.18 | 6.21 | p < 0.001 | |
Deficient (5) | 37 | 10.82 | 5.80 | p < 0.001 | |
Insufficient (6) | 27 | 9.70 | 6.17 | p < 0.001 | |
