社区设施是否与更多的步行和更少的驾驶有关？是的，但只对有钱人
Are neighbourhood amenities associated with more walking and less driving? Yes, but only for the wealthy
摘要：
城市拥有大量的便利设施，从当地的理发店到科学博物馆和购物中心。但这些都是分布在城市空间中的不平等。使用Google Places数据结合哥伦比亚波哥大基于出行的移动数据，我们揭示了社区设施对城市移动模式的影响。推导出一个新的可访问性度量，明确考虑到空间范围，我们发现，当地设施的密度较高的步行以及较短的巴士和汽车旅行的可能性较高。更深入地挖掘，我们使用一个样本分层框架，以表明社会经济地位（SES）调节这些影响。仅对于最富有的群体来说，半径约1公里范围内的设施与更高的步行倾向和更少的驾驶时间密切相关。相比之下，较高密度的设施与较短的巴士行程为低和中等SES居民。随着全球城市致力于促进公共交通和绿色出行，这些发现使我们能够更好地了解商业结构如何在高度收入隔离的环境中塑造城市流动性。
英文摘要：
Cities are home to a vast array of amenities, from local barbers to science museums and shopping malls. But these are inequality distributed across urban space. Using Google Places data combined with trip-based mobility data for Bogotá, Colombia, we shed light on the impact of neighbourhood amenities on urban mobility patterns. Deriving a new accessibility metric that explicitly takes into account spatial range, we find that a higher density of local amenities is associated a higher likelihood of walking as well as shorter bus and car trips. Digging deeper, we use a sample stratification framework to show that socioeconomic status (SES) modulates these effects. Amenities within about a 1km radius are strongly associated with a higher propensity to walk and lower driving time only for only the wealthiest group. In contrast, a higher density of amenities is associated with shorter bus trips for low and middle SES residents. As cities globally aim to boost public transport and green travel, these findings enable us to better understand how commercial structure shapes urban mobility in highly income-segregated settings.
