论文摘要
从当地理发师到科学博物馆和购物中心，城市都是各种各样的便利设施的所在地。但是这些是分布在城市空间中的不平等。使用Google Places数据以及哥伦比亚波哥大的基于旅行的移动性数据，我们阐明了邻里便利性对城市流动性模式的影响。通过明确考虑空间范围的新的可访问度量，我们发现较高的局部设施密度与步行以及较短的巴士和汽车旅行的可能性更高。深入研究，我们使用样本分层框架来表明社会经济状况（SES）调节了这些影响。大约1公里半径内的设施与仅适用于最富有的群体的较高行走和较低驾驶时间的倾向密切相关。相比之下，更高的设施密度与低和中间SES居民的公交旅行较短有关。随着全球城市旨在促进公共交通和绿色旅行，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分离的环境中塑造城市流动性。
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.
