Research on the Spatial and Temporal Dynamics of Crowd Activities in Commercial Streets and Their Relationship with Formats—A Case Study of Lao Men Dong Commercial Street in Nanjing

Abstract

Crowd activity is an important indicator of commercial streets’ attractiveness and developmental potential. The development of positioning technologies such as GPS and mobile signal tracking has provided a large amount of trajectory data for studying crowd activities on commercial streets. These data can not only be used for the statistics, extraction, and visualization of crowd information, but they also facilitate the exploration of deeper insights into dynamic behaviors, choices, trajectories, and other details of crowd activities. Based on this, this article proposes a new framework for analyzing crowd activities to explore the spatial activity patterns of crowds and understand the dynamic spatial needs of people by analyzing their correlations with local formats. Specifically, we analyze the spatial activity characteristics of a crowd in the Lao Men Dong Commercial Street area by identifying the stay points and trajectory clusters of the crowd, and we establish a regression analysis model by selecting commercial street format variables to evaluate their impact on crowd activities. Through case analysis of the Lao Men Dong Commercial Street, this study confirms that our method is feasible and suitable for spatial research at different scales, thereby providing relevant ideas for format location selection, spatial layout, and other planning types, and for promoting the sustainable development of urban spaces.

Research on Optimization Strategy of Commercial Street Spatial Vitality Based on Pedestrian Trajectories

“…In commercial pedestrian streets, particular emphasis is placed on how the functional attributes of the street, spatial form, and facilities affect micro-individual activities [9,21]. Drawing from the literature, this study identifies key factors that significantly affect spatial vitality in the micro-spaces of commercial streets, such as store density [22], store types [23], ground floor interface permeability [24], pedestrian width [25], the number of public tables and chairs [26], and billboard area [27]. Leveraging established research methods, scholars continue to investigate the influence of street elements on spatial vitality.…”

“…Store type [23] refers to the variety of functional store categories found on commercial pedestrian streets. This metric reflects the diversity of shopping, dining, entertainment, and service options available.…”
