Centered on the theme of “building a new smart city benchmark, making city smarter and life better”, the “comprehensive solution for building a smart city” by Shenzhen integrates the city’s people-oriented concept of smart city construction, and provides several highlight cases. The jury committee believes that Shenzhen has comprehensively demonstrated its innovative solutions in key areas such as enabling technology, transportation, energy and environment, governance, industry and economy, livability and inclusiveness, infrastructure and construction, and created an intelligent and humanistic digitalized city by its unique urban philosophy, foundation and landscape.
With respect to urban governance, Shenzhen has preliminarily built up the digital twin base for the city area, which combines nearly 10,000 BIM refined models of major buildings, forms the digital twin data system covering three primary categories (urban basic space, management targets and IoT perception) and 25 subdivisions, and offers 4,000+ data services. The city has created 200+ digital twin application scenarios including one graph for urban water management, one graph for power charge, storage and discharge, planning and design of the 5th-phase rail transit, and promoted the application of digital twins in urban areas like Houhai, Xiangmihu and Guangming Science City. For example, by creating applications for urban flood prevention and relying upon the graph for urban water management, flood disaster risk model and contingency plans for different working conditions, Shenzhen utilizes 3D models to carry out simulation of flood in key districts and analysis of affected areas, reinforce the accuracy of identifying water-logging risks and explore new paths of addressing the issue. The Xiangmihu digital twin comprehensive application depends on high rendering capability to visually present complex surface and underground space planning, assists in digital decisions such as city silhouette review, urban landscape design, and advances the establishment of a lifecycle digital twin management model of key districts including planning, design, construction and operation.
