Abstract

Trajectory data is commonly used in environmental behavior studies to explore the relation between the built environment of commercial streets and urban vitality. However, there is a lack of in-depth research on the combined effects of pedestrian mobility characteristics, which are crucial for the design and management of pedestrianized commercial streets, and built environment factors. By analyzing trajectory data from two similarly designed pedestrian commercial streets—Beijing's Sanlitun Taikoo Li South and Chengdu's Taikoo Li, the XGBoost model is utilized to conduct a quantitative analysis of the combined impact of built environment factors. The results indicate that, in terms of time, pedestrianized commercial streets exhibit the highest vitality on non-working day evenings. Spatially, the main streets show higher vitality than secondary streets. The contribution of each factor to the results is quantified using the average Shapley values, with the most influential environmental factors being the intensity of anchor stores (4.44%), the number of seating areas (3.08%), and the green view index (2.09%). The combination of anchor store intensity and green view index has the most pronounced cross-temporal and cross-regional effect, while the interaction of anchor store intensity, green view index, and street width collectively enhances street vitality.

商业街步行活力特征——考虑时间、空间和建成环境因素

轨迹数据是环境行为研究中常用的数据，用于探索商业街建成环境与城市活力之间的关系。然而，对于步行街设计与管理中至关重要的行人流动性特征与建成环境因素的综合影响，缺乏深入的研究。通过分析北京三里屯太古里南和成都太古里两条设计相似的步行街的轨迹数据，利用XGBoost模型对建筑环境因素的综合影响进行定量分析。结果表明，从时间上看，商业街步行街在非工作时间的晚上表现出最高的活力。在空间上，主街比次街更具活力。每个因素对结果的贡献使用平均Shapley值进行量化，其中影响最大的环境因素是锚店强度（4.44%），座位区域数量（3.08%）和绿色景观指数（2.09%）。锚店强度与绿色景观指数的组合具有最显著的跨时间和跨区域效应，而锚店强度、绿色景观指数和街道宽度的相互作用共同增强了街道活力。

期刊介绍： Frontiers of Architectural Research is an international journal that publishes original research papers, review articles, and case studies to promote rapid communication and exchange among scholars, architects, and engineers. This journal introduces and reviews significant and pioneering achievements in the field of architecture research. Subject areas include the primary branches of architecture, such as architectural design and theory, architectural science and technology, urban planning, landscaping architecture, existing building renovation, and architectural heritage conservation. The journal encourages studies based on a rigorous scientific approach and state-of-the-art technology. All published papers reflect original research works and basic theories, models, computing, and design in architecture. High-quality papers addressing the social aspects of architecture are also welcome. This journal is strictly peer-reviewed and accepts only original manuscripts submitted in English.
