Abstract:This report focuses on the relationship between walking and its contributing factors by
applying spatial regression methods. Using the Vermont data from the New England
Transportation Survey (NETS), walking variables as well as 170 independent variables are
derived including some through spatial analysis with Geographic Information Systems
(GIS). Among those independent variables, people’s lifestyle and perception of the built
environment variables are included. A linear regression model is first established to serve
as a base model for comparisons with spatial regression models. The results reveal that
people’s lifestyle and perception of the built environment are significant variables
explaining Vermonters’ walking behavior. Methodologically, the results reveal that no
spatial effect is found and that there are no significant differences between the linear and
spatial regression models. Therefore, the study concludes that it may be appropriate to
apply traditional non-spatial statistical tools to analyze the relationship between walking
and its contributing factors. However, the study suggests that researchers examine
whether spatial effect exists in these inherently spatial behaviors before using only
traditional statistics. This caution is particularly relevant as methods to estimate spatial
models become more commonplace and easily available. The two spatial methods used in
this report both reveal small but different challenges.
