Abstract:
The living circle model is based on three key elements-residents, which are travel characteristics, and facility points. However, neglecting the differences between these three elements can lead to a mismatch between the supply and demand of public service facilities in practical applications, resulting in the phenomenon of 'living circle is not for living'. It is particularly evident in small cities, where the analysis of the relationship between different residents' travel characteristics and facility points is limited by the community living circle model of larger cities. To address this issue, the author analyzed and studied data from social satisfaction questionnaires, urban physical examination data, and open-source big data in Pu'er City of Yunnan Province. The study find that the quantitative results of the public service facility layout index in the community living circle of small cities are inconsistent with the satisfaction results of residents regarding public service facility services. As a result, goal-oriented public service facility planning with a balanced layout is not practical in small cities. To address these issues, the author proposes reconstructing a new living circle for small cities that is in line with the travel characteristics of local residents and redefining the division standard. Instead of adjusting the public service facility layout based on a single factor, the full-factor optimization of the whole process of residents' travel should be considered, and the balanced goal of public service layout should be replaced with the result of residents' satisfaction. Based on the reconstructed new living circle in small cities, the author proposes optimizing the layout of public service facilities based on the actual needs of residents and combined with multiple travel modes to formulate practical and effective layout strategies for public service facilities.
