Description
Against the backdrop of global sustainable development, China has proposed the concept of "Station-City Integration," aiming to promote the functional integration of cities and high-speed rail (HSR) hub areas, attract foot traffic, and create new urban vitality centers. As a sub-center of Shanghai, the Hongqiao Business District serves as a high-level urban public activity center.
However, China's HSR hub areas are predominantly characterized by strong transportation attributes, which weaken their commercial and residential service appeal, and caused a core issue persists: despite their designation as new urban public activity centers, local residents exhibit low activity frequency, resulting in weak recreational vitality.
This study takes Hongqiao Business District as an example to explore the recreational vitality of HSR hub areas from the spatiotemporal behavior perspective of recreational populations, focusing on the urban contribution to foot traffic in these areas. Recreational populations are defined as those who stay within the district's public activity center for over one hour. By examining their spatiotemporal behavior characteristics, this study identifies recreational demands and provides targeted strategies for enhancing public activity facilities in HSR hub areas.
(1) Measurement of Recreational Vitality in Hongqiao Business District
By using mobile signal data, the study identifies the origin-destination distribution and spatiotemporal characteristics of the recreational population. The service area of public activities within the hub is delineated, and recreational vitality is measured. The recreational activity volume at each base station is calculated, weighted by the duration of stays—higher activity volumes indicate longer and more frequent stays.
(2) Recreational Characteristics and Influencing Mechanisms of Local Residents
The study identifies the resident population within the service area and analyzes their spatiotemporal behavior characteristics. A residential-recreational functional network is constructed, and the recreational vitality of public activity centers is measured as the dependent variable. Independent variables include land use, service facilities, spatial connections, and development intensity, derived from the strength and direction of network's edge. A regression model is built to analyze the formation and influencing mechanisms of the residential-recreational network.
Field surveys are conducted to investigate the travel and activity patterns of residents within the service area. Travel logs capture outdoor mobility information; Activity logs provide insights into indoor activities and multi-purpose trips; And time-use logs detail indoor activities and the "stages" constituting travel. Questionnaire surveys further refine the findings from big data analysis, enabling a more sophisticated study of residents' spatiotemporal behavior characteristics.
(3) Strategies for Enhancing Recreational Vitality in Hongqiao Business District
Perspective of Residents: Enhance the functional richness of high-speed rail hub areas to strengthen their core competitiveness as urban functional nodes. Optimize the provision of living service facilities within the high-speed rail hub areas to satisfy the diverse travel demands of local residents.
Perspective of Space: Promote integrated land-use development in and around high-speed rail hub areas, emphasizing three-dimensional development of public activity centers, both above and below ground. Additionally, establish a well-connected slow-traffic network to improve spatial organization.
Perspective of Connectivity: Enhance the public transport and pedestrian accessibility of high-speed rail hub areas and associated public activity centers, ensuring arrival and entry for residents.
This study analyzes the activity characteristics of residents in HSR hub areas from a spatiotemporal behavior perspective, investigates the influencing mechanisms of recreational vitality, and proposes strategies to enhance vitality from 3 dimensions: urban areas, station areas, and station-city areas. The findings enrich the theoretical framework of urban vitality studies, provide practical references for the development of public activity centers in HSR hub areas, and optimize the interaction between station and city. Ultimately, the study offers insights into the evolution of station-city relationships and contributes to the theoretical advancement of station-city integration.
