交通导向型开发（TOD）一直是开发密集城市形态的关键问题之一。在 TOD 中捕捉密集城市形态对人类规模的影响仍然缺乏探索。本研究旨在设计人性化的测量方法来调查 TOD 中地铁站周围的区域，重点关注物理环境与居民活动之间的相互作用。我们在建筑层面的 GIS 中采用了城市网络分析 (UNA)，并通过五个指标（范围、介数、重力、接近度和直线度）来描绘 TOD 区域的空间配置；收集 Facebook 签到和兴趣点 (POI) 数据，以捕捉居民的社交活动；并利用空间滞后模型综合城市形态属性和社会活动，以探索空间相关性。 800米TOD半径内的城市形态对POI和社会活动的空间分布具有显着影响。传统街区具有高可达性、高引力和高间性的特征，具有空间分布均匀、丰富的设施、服务和社会活动的城市功能；而综合开发街区具有高亲近性，具有集聚的设施、服务和社会活动功能。此外，居民的社交活动随时间的变化而变化，一般发生在闲暇时间的高重力区域。通过密集的道路网络、小街区、小巷和直接联系来加强城市形态，将鼓励社会活动并提高居民获得设施和服务的便利性。城市形态遵循邻里功能，决定了良好的街道生活的服务、设施和社会活动。
Transit-oriented development (TOD) has been one of the critical concerns for developing dense urban form. Capturing the human-scaled effects of dense urban form in TOD remains poorly explored. This study aims to devise human-scaled measurements to investigate the areas around metro stations in TOD, focusing on the interaction between the physical environment and residents' activities. We employed Urban Network Analysis (UNA) in GIS at the building level with five metrics—Reach, Betweenness, Gravity, Closeness, and Straightness—to delineate the spatial configurations of TOD areas; compiled Facebook check-in and points of interest (POIs) data to capture residents' social activities; and synthesized urban form attributes and social activities with a spatial lag model to explore spatial correlations. Urban forms within an 800-m TOD radius have significant impacts on the spatial distribution of POIs and social activities. Traditional neighborhoods are characterized by highReach,Gravity, andBetweenness values, equipped with spatially evenly distributed and rich urban functions of facilities, services, and social activities, whereas integrated development neighborhoods are associated with highCloseness valuesand are equipped with agglomerated facilities, services, and social activities. Furthermore, the residents' social activities vary by time and generally happen in highBetweennessandGravityareas during leisure hours. Strengthening urban form through dense road networks, small blocks, side streets, and direct linkages will encourage social activities and enhance residents’ accessibility to facilities and services. Urban form follows neighborhood functions that determine a good street life of services, facilities, and social activities.
