Older adults\u2019 walking behavior is determined by many factors, such as socioeconomic attributes and the built environment. Although a handful of recent studies have examined the influence of street greenery (a built environment variable readily estimated by big data) on older adults\u2019 walking behavior, they have not focused on the spatial heterogeneity in the influence. To this end, this study extracts the socioeconomic and walking behavior data from the Travel Characteristic Survey 2011 of Hong Kong and estimates street greenery (the green view index) based on Google Street View imagery. It then develops global models (linear regression and Box\u2013Cox transformed models) and local models (geographically weighted regression models) to scrutinize the average (global) and location-specific (local) relationships, respectively, between street greenery and older adults\u2019 walking time. Notably, green view indices in three neighborhoods with different sizes are estimated for robustness checks. The results show that (1) street greenery has consistent and significant effects on walking time; (2) the influence of street greenery varies across space\u2014specifically, it is greater in the suburban area; and (3) the performance of different green view indices is highly consistent.<\/jats:p>","DOI":"10.3390\/ijgi10090596","type":"journal-article","created":{"date-parts":[[2021,9,10]],"date-time":"2021-09-10T10:31:34Z","timestamp":1631269894000},"page":"596","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":86,"title":["Spatially Varying Effects of Street Greenery on Walking Time of Older Adults"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6070-9044","authenticated-orcid":false,"given":"Linchuan","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Urban and Rural Planning, School of Architecture and Design, Southwest Jiaotong University, Chengdu 611756, China"}]},{"given":"Jixiang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Urban Planning and Design, Faculty of Architecture, The University of Hong Kong, Hong Kong 999077, China"}]},{"given":"Yuan","family":"Liang","sequence":"additional","affiliation":[{"name":"Urban Mobility Institute, Tongji University, Shanghai 200092, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7614-6661","authenticated-orcid":false,"given":"Yi","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Architecture and Civil Engineering, City University of Hong Kong, Hong Kong 999077, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3608-1936","authenticated-orcid":false,"given":"Hongtai","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Transportation and Logistics, Southwest Jiaotong University, Chengdu 611756, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1126\/science.1254405","article-title":"Economic and social implications of aging societies","volume":"346","author":"Harper","year":"2014","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"141091","DOI":"10.1016\/j.scitotenv.2020.141091","article-title":"Implementing on-site construction waste recycling in Hong Kong: Barriers and facilitators","volume":"747","author":"Bao","year":"2020","journal-title":"Sci.
