*2.2. Data Collection*

The study started with site observation, guided by POE (Post Occupancy Evaluation) method [39]. The authors aimed to record the diverse activities on site and the relationship between activities and spaces. After that, questionnaires and structured interviews were conducted several times in January, September and October 2019, covering the daytime of both workdays and weekends by using

intercept surveys. The intercept survey has been proved to be practical in previous studies on greenway research [32,40]. Two questionnaires were used during the survey. The first one was to study site demographics and usage patterns as adapted from Gehl's theory [36]. According to the analysis and summary of the results of this questionnaire, the second questionnaire was designed for the evaluation of the community greenway. We collected data along the community greenway on October 2 and 4, 2019 respectively for the two questionnaires. The users were randomly instructed to cover diverse groups of people.

For the study instrument, the two questionnaires were used to study the demographic information, use patterns, evaluation and opinions on different construction elements. For use patterns, residents were asked how they came to the community greenway, how long it took by walking, how often they used it, how long they usually stayed and what kind of activities they did (commuting/recreation/exercising/ shopping/interacting with neighbors and family members). The evaluation included the conditions of construction elements (accessibility, traffic environment, facilities, activity space, connectivity with other urban living facilities, and overall satisfaction with the community greenway) and the impact of community greenway on the daily life (transportation, leisure activity, neighborhood activity, family activity and shopping). The options provided are 'very satisfied', 'satisfied', 'general', 'dissatisfied', 'very dissatisfied'. The items are based on previous research on greenways [13,15,24,32,41,42] and the results of observations. To learn residents' evaluation on the importance of different construction elements, participants were asked to score the importance of factors in construction (very important/important/ general/unimportant/very unimportant). Besides, the results were combined with structural interviews, recording other concerning factors.
