Exploration of Temporal City Planning in Shanghai: The Time Path for the 15-minute Community Life Unit
Abstract：
The role of communities as the basic unit of urban innovation and development is gradually being strengthened, especially after integrating the time dimension into the community planning and construction system, which greatly changes the understanding of community functional structure, spatial organization, and governance operation models. In 2014, Shanghai was the first in China to propose the unit concept of “15-minute community life unit” based on the perspective of temporal and spatial behaviors, respecting the development and changes of the city, strengthening the comprehensive management of various temporal elements of the community, and actively responding to the changing trends and complex demands of community social structure under the background of urbanization and globalization. By analyzing the evolution characteristics and typical practices of Shanghai “15-minute community life unit” concept, three main time paths in Shanghai community planning exploration are proposed. First, by optimizing the spatiotemporal structure of the life circle as a whole, the temporal value of community space is systematically enhanced. Second, by accurately guiding the spatiotemporal matching of individual behavior. The third is to respond to the full-time demands of community life in multiple dimensions through more resilient spatiotemporal dynamic governance. In the context of humanistic value oriented regression, the organization and implementation evaluation of relevant strategies will provide reference and inspiration for the practical application of temporal city planning at the community level in various regions.
