This thesis analyzed the influence of objective and subjective walkability on momentary hedonic and eudaimonic well-being while walking in neighborhoods. For this purpose, two neighborhoods with different objective walkability, and equal eye-level street greenery levels were chosen. Consequently, a survey was conducted with two hundred and nine neighborhood residents in total. The residents were asked about their perceptions regarding their neighborhood’s walkability levels, and momentary hedonic and eudaimonic well-being during walking in their neighborhoods. The results showed that objective walkability did not have a positive influence on perceived walkability, hedonic and eudaimonic well-being. However, the data analysis indicated a positive moderate correlation between perceived walkability and momentary hedonic and eudaimonic well-being. The outcomes of this thesis provided new insights to researchers for means to facilitate and support momentary subjective well-being through perceived walkability dimensions.
