In the future urban development picture, from clothing, food, housing and transportation, to system operation, the proportion of "wisdom" will be sufficient.
Mainland China proposes to strengthen urban infrastructure construction and build livable, resilient and smart cities. Improving urban operation efficiency through digitalization and continuously solving practical problems in urban governance is an important way to improve the level of urban governance.
Smart city refers to the new concept and new model of using a new generation of information technology to promote urban planning, construction, management and service intelligence. With the continuous acceleration of urbanization, the complexity of urban affairs is not the same, the efficiency requirements are also different, in order to adapt to the latest urban form and meet higher management needs, the new trend of smart city - "new smart city" came into being.
New smart cities, where is "new"?
First, public services have been fully upgraded. The evaluation index of the new smart city clarifies the key construction content and development direction of the new smart city in the form of evaluation index. Among them, benefiting the people, precise governance, ecological livability, information infrastructure, information resources, industrial development, information security, innovative development, etc., have become part of objective indicators. Based on the primary and secondary indicators, local governments can accurately focus on these areas, carry out digital transformation, and provide more convenient, efficient and comprehensive public services for the public.
It has gradually become a trend to improve the level of grassroots smart governance with digital empowerment. In Jining City, Zhongdu Subdistrict is located in the main urban area of Wenshang, with jurisdiction over 14 urban communities and 5 administrative villages, with a complex population composition and a large floating population, making community management very difficult. Relying on the county-level nodes of the integrated big data platform, Zhongdu Street applied to call various data interfaces provided by the departments of human resources and social security, medical insurance, and health care, compared with the basic population database, directly generated one person and one file "data portrait", combined with the daily visits of grid members, to achieve the full aggregation of information such as population, housing, special groups, and business entities in the jurisdiction. Since the beginning of this year, it has taken the initiative to solve more than 10 types of matters for 1,351 people, such as missing medical insurance, handling old-age subsidies, and subsidies for the disabled.
Second, new smart cities show unique advantages in urban infrastructure. The infrastructure of traditional cities often has bottlenecks, such as road congestion and parking difficulties. The new smart city realizes intelligent traffic management by introducing intelligent transportation systems.
Through intelligent signal lights, smart street signs and other equipment, it can accurately control traffic flow, optimize road planning, reduce traffic congestion, and improve traffic efficiency. At the same time, the new smart city also uses big data and artificial intelligence technology to analyze traffic data and provide real-time traffic information to residents, helping them choose the best travel route and reduce travel time.
July and August is the peak tourism period of Rizhao, and at the Rizhao City Brain Operation Command Center, more than ten government workers from various positions such as urban management, market supervision, and cultural tourism will work together every day. When traffic congestion is found, relying on real-time perception of IoT devices and intelligent analysis of the "city brain", urban incident work orders can be generated in time and transferred to relevant departments such as traffic police for efficient disposal to ensure smooth urban roads.
Third, "data-driven" has become an important power source for urban operation. Focusing on the whole life cycle of the planning, collection, circulation, analysis, feedback and revision of data of various systems and departments, using information flow optimization to drive the construction and improvement of systems in various fields is the main content of the current new smart city construction.
For example, if a coastal city encounters a typhoon transit, how many levels of typhoon? How much rainfall? What are the low-lying spots in the city? We can determine one by one through AI models and simulation systems to achieve early prevention, rather than doing "hindsight" and waiting for disasters to occur and then rescue and disaster relief. Which buildings and which streets in the city may be flooded, the "city brain" can directly give the answer, and even restore it 1:1 in the digital twin system.
Whether it is "data-driven" or "service upgrade", in the final analysis, it is the needs of "people" that are respected and further amplified. "The city is the city of citizens", and the construction of a new smart city needs to meet the needs of the people for smart life. Shandong organized and carried out the "Ask the People" activity for the construction of a new smart city, listened to more than 3 million opinions and suggestions, and researched and launched pragmatic and effective solutions.
However, the construction of smart cities is not a "one-man show", it is necessary to break down the data barriers between various departments, pay attention to market and social forces, and form a multi-party participation pattern. Smart cities include smart government, smart people's livelihood, intelligent support of urban infrastructure, and smart ecological environment of cities. Among them, the role of "smart government" is particularly important, intuitively understood that if the government's organizational structure and institutional mechanisms are not rationalized, departmental interests are not broken, information resources cannot be shared, business cannot be coordinated, and systems cannot be integrated and integrated, smart city construction cannot be truly implemented.
Smart cities should be reformed through systems and mechanisms, and the problems and obstacles encountered in construction should be eliminated with the idea of reform. In the construction, it is necessary to build corresponding systems for the most concerned, most personal and urgent issues of the masses, such as medical care and education. At the same time, we must be good at using social forces to promote construction, so that we can not only spend small money to do big things, but also cultivate and cultivate a number of emerging industries.
Cities belong to the people, urban development for the people, the new smart city must always focus on the core element of "people", guided by the needs of the masses, promote the construction to be practical and detailed, and realize the organic unity of high-quality urban development and residents' high-quality life.
