As urbanization gradually accelerates, serious problems such as traffic congestion, energy, social security and environmental pollution have arisen, and some of the remaining problems must be solved. For example, the lack of long-term management of idle spaces has resulted in waste of idle space resources or some criminal activity, which is very detrimental to the healthy development of the city. Therefore, there is a need to improve these problems. In order to solve the problem of urban development, various countries are actively promoting smart city construction. Smart cities have great implications for the planning, management, operation and long-term development of cities. At the time of the initial construction of the smart city, the design was dispersed and the resulting idle space caused many social problems and had a negative impact. Idle space is a result of urban development and is also an important resource for urban renewal. This study aims to renovate the idle space under the overpass in the city to attract people to the underpass of the overpass, to revitalize the area and improve the cohesion of residents, and to increase the node and connectivity between regions. In the context of national smart city construction, we actively seek solutions to make the most of urban idle space, help smart city construction, achieve balanced development of economy, technology, and society, and bring economic and social benefits. Study the structure and characteristics of the space under the overpass, combine the concept of spatial renovation of the smart city, and meet the development needs of the smart city, seek a new direction of development that combines the possibility of renovating the space under the overpass and the new concept, and propose a comprehensive solution. This study provides a sample of future cities promoted as innovations for urbanization change by expanding the use of underground spaces, building a smart, efficient and livable new city, building a leading digital city, and improving the happiness of residents. It gives implications for research, development, and improvement of space. This study mainly used research methods such as literature research and analysis, case research and comparative analysis, and field research. This study can draw conclusions and remodeling schemes for the idle space under the overpass by analyzing the problem and case analysis of the space design of the smart city space and the space under the overpass. The problem-solving direction is to first improve the existing problems of the space under the elevated road. After improving the space problem, it is possible to increase the functionality and effect by using the space. Lastly, it is necessary to add the necessary smart elements to the smart city to make it a space that meets the needs of the smart city. Providing public spaces by increasing road entrances can effectively improve the convenience of space and greatly reduce the space vacancy rate. Reduce the development of buildings with high strength and destructive properties, effectively mitigate urban environmental pollution, purify the surrounding air, protect the urban ecological environment, and improve environmental performance through green vegetation planting, landscape modeling exhibits, and the use of eco-friendly technologies and materials. I can. This paper is then referred to for research on improving the idle space under the overpass of the smart city.
