Smart cities are the inevitable trend of the future, especially in the context of rapid development of science and technology. So what is a smart city? Why build a smart city? What are the impacts of smart cities on residents' lives and socio-economic development? This article will provide a complete overview of relevant issues of sustainable urban development. From there, support all levels and sectors to soon realize smart cities in Vietnam.

What is smart city?

Smart city is understood as a city that uses information and communication technology to create, implement and promote development activities to create sustainable infrastructure to promote socio-economic growth, improve the quality of life for the people.


Why build a smart city?

54% of the world's population lives in cities and this number is expected to grow to 66% by 2050, adding 2.5 billion people to the urban population over the next three decades. With this expected population growth, there is a need to manage the environmental, social and economic sustainability of resources.


Building smart cities is an inevitable trend in the digital age


Smart cities enable efficient management of assets and resources in urban environments, exploiting their potential optimally towards sustainable development.

The services and applications of the smart city will create new products, services and utilities that contribute to improving the quality of life for people.

Smart city innovation also delivers new value from existing infrastructure while generating new revenue streams and operational efficiencies to help save governments and citizens money.


Features of smart cities

The main goal of a smart city is to optimize city functions and promote economic growth while improving the quality of life for residents using smart technologies and data analytics. .

The smartness of a city is defined using a range of characteristics, including:

  • Technology-based infrastructure
  • Environmental initiative
  • Efficient and highly functional public transport
  • Confident and progressive city plan
  • People can live and work in the city, using the city's resources

Besides using information and communication technologies, smart cities operate on the principle of analyzing databases to choose the right solutions and find ways to improve.


Smart city technology

Smart cities use a variety of software, user interfaces, and communication networks along with the Internet of Things (IoT) to provide connected solutions to the public. Among them, IoT is the most important. IoT is a network of connected devices to communicate and exchange data. This can include anything from vehicles to home appliances and sensors on the street.


IoT technology – connecting things using the Internet


Besides IoT solutions, smart cities also use technologies including:

  • Application Programming Interface (API)
  • Artificial Intelligence (AI)
  • Cloud Computing Service
  • Dashboard
  • Machine learning
  • Machine-to-machine communication
  • Net

Features of smart cities

Combining automation, machines, and IoT is enabling the adoption of smart city technologies for a variety of applications. For example, smart parking can help drivers find a parking space and can also enable digital payments.


  • Smart city initiatives are used to combat climate change and environmental pollution.
  • Provide safety measures: monitor crime-prone areas; use sensors for early warning of incidents such as floods, landslides, hurricanes or droughts.
  • Smart buildings offer real-time space management or structural health monitoring and feedback to determine when repairs are needed.
  • Residents access this system to notify officials of problems such as potholes, leaks in water pipes, damaged electrical wires, etc.


Smart cities help improve people's lives, effectively exploit environmental resources towards sustainable and prosperous development.


Smart cities can connect all service modes to provide integrated solutions for residents.

How smart cities work

Smart cities follow four steps to improve quality of life and enable economic growth through networks of connected IoT devices and other technologies. These steps are as follows:

  1. Collect: Smart sensors collect real-time data
  2. Analytics: Data is analyzed to better understand the performance of city services and activities
  3. Communication: Data analysis results are communicated to decision makers
  4. Action: Action taken to improve operations, manage assets, and enhance the quality of city life for residents

The ICT framework gathers real-time data from connected assets, objects, and machines to improve decision making.

Challenges of smart cities

For all the benefits that smart cities offer, there are also challenges to overcome. Understanding the challenges and understanding the root of the problem will help the government and investors overcome difficulties in the smart city development process.


  • Urban infrastructure needs to be upgraded to match the planning and orientation of a smart city, which consumes a lot of money during the transition.
  • Connected IoT and sensor technology make information security difficult, hackers can penetrate, causing difficulties in management and operation.
  • The fact that there are too many CCTV cameras around and the IoT connection system that constantly updates user data affects human psychology, causing a decline in labor quality.
  • Changing people's habits from using traditional products and services to IT innovation takes time and continuous, long-term education.
  • A population group that is difficult to adapt to the innovation of applying technology to life, especially in rural areas and the elderly, creates disparities between regions and people to people.


Technology is the core factor that leads and affects efficiency in the process of building and developing smart cities. However, people have always been the focus of development. Therefore, only when technology, government and people work together to improve the quality of life, then the city is truly "smart".
