Description
Contemporary urban development is gradually shifting from "incremental expansion" to a high-quality development model characterized by "stock optimization" and "people-centered" approaches. The concept of the "Future Community Living Circle" has garnered widespread attention, focusing on meeting residents' diverse and personalized daily needs and enhancing life satisfaction through the meticulous provision of public service facilities. However, traditional residential planning based on the "per thousand population" metric often exhibits issues such as single functionality, facility shortages, and extensive spatial layouts. As urban social spatial differentiation and social segregation intensify, the quantity and quality of community public service provision struggle to meet residents' demands for equity and satisfaction, notably reflected in significant disparities in accessibility.
Against this backdrop, the evaluation and optimization of public service accessibility for "Future Community Living Circles" have become critical topics. Internationally, the concept of accessibility encompasses rights accessibility, opportunity accessibility, spatial accessibility, and usage accessibility, with research expanding from "health care accessibility" to "social public service accessibility." Methodologically, studies frequently employ the Two-Step Floating Catchment Area (2SFCA) method, questionnaire-based satisfaction surveys, and the 5A framework, alongside the rise of interdisciplinary research that emphasizes the integrated planning of facility layouts from regional, spatial, and people-centered perspectives. However, existing research predominantly focuses on the quantitative supply of public service facilities and the measurement of accessibility, insufficiently exploring whether facility configurations align with residents' daily activity trajectories and travel habits, as well as lacking classification studies on the differentiated needs of various population groups (e.g., different age groups, social strata). Consequently, when assessing whether public service provision accurately meets residents' needs, it is challenging to comprehensively represent the fairness of public service facilities across different groups in terms of activity timing, travel modes, and usage preferences.
Addressing these gaps, this study takes Yangpu District in Shanghai, China, as a case study to evaluate and optimize the accessibility of public service facilities within the "Future Community Living Circle" framework. Incorporating a "place-based and people-centered" research perspective, the study utilizes Mobile Signaling Data, Points of Interest (POI) data, and survey data to construct a comprehensive, multidimensional accessibility analysis framework encompassing the entire "supply-service-feedback" process. In designing the evaluation indicator system, this research considers the usability dimension—whether the number of facilities matches the population size of different age groups—and the accessibility dimension—whether facility layouts facilitate convenient travel for various age groups. Additionally, the adaptability dimension incorporates the alignment with spatiotemporal behavioral characteristics and residents' satisfaction. Based on these dimensions, the study synthesizes the accessibility levels of each research unit, aiming to precisely assess the alignment between public service provision and the needs of residents across different age groups and to propose optimization strategies.
The findings reveal that, from a "people-centered" perspective, different age groups exhibit significant variations in facility needs, manifested in aspects such as facility operation and maintenance, types, and functionalities. From a "place-based" perspective, uneven spatial distribution of facilities leads to disparities in quantity, location, and quality. Integrating the comprehensive accessibility analysis, this study establishes an "identify-optimize-enhance" system to recognize different regional types and propose targeted optimization strategies. These strategies aim to precisely match public service facilities with residents' needs, enhance overall accessibility, and promote the high-quality development of "Future Community Living Circles."
