What is a Smart City?

Smart cities use IoT technology to become more efficient and sustainable by reducing pollution, improving public safety, and increasing the efficiency of city services. IoT devices can be used to monitor everything from traffic and weather conditions to air quality and energy use. This data can then be analysed to help city planners make informed decisions about how to improve the city for its residents. With the number of IoT devices expected to reach 75.44 billion by 2025, more and more cities are beginning to incorporate smart city technology into citizens’ way of life (http://www.researchgate.net/figure/Internet-of-Things-prediction-from-2014-to-2025-in-billions_fig2_339121533, 2020).

Why Do We Need Smart Cities?

As the world becomes more urbanised, it is important to find ways to make cities more sustainable and liveable. Smart city initiatives are one way to do this. According to a report from the United Nations, 66% of the world’s population will live in cities by 2050, which means that there will be an increased demand for services and infrastructure, putting a strain on resources. By using a set of technologies for accessing the data collected by various devices through wireless and wired Internet networks” cities can become more connected, improving the efficiency of daily life (V, 2023). Smart city initiatives can help to reduce the impact of this urbanisation by making cities more efficient and sustainable. This is important not only for the environment but also for the quality of life of city residents.

Advantages of IoT in Smart Cities:

There are many advantages of using IoT in smart cities, including:

• Reducing pollution: IoT can be used to monitor air quality and energy use. This information can then be used to help reduce pollution in the city.
• Improving the quality of life for city residents: By making cities more efficient and sustainable, IoT can help to improve the quality of life for city residents. In fact, 98% of people living in smart cities are satisfied with the facilities available to them (http://www.sciencedirect.com/science/article/pii/S266734522100002X, 2021).

10 Examples of Smart City Technology

Smart city devices can be used for a variety of purposes, from monitoring traffic to reducing pollution. Here are some examples of smart applications of IoT:

1. Smart waste management: IoT devices can be used to monitor rubbish levels and track the pick-up of refuse trucks. This data can then be used to improve the city’s waste management efficiency.
2. Smart traffic management: Traffic data can be collected and analysed using IoT devices to help city planners improve the flow of traffic, reducing congestion and making journeys quicker and smoother.
3. Smart street lighting: LED lights fitted with sensors can be used to save energy and improve public safety. For example, they can be dimmed or turned off when there is no one around, and they can be used to provide lighting for pedestrian walkways.
4. Smart air quality monitors: The City Air Management Tool is a smart air quality monitor that detects the level of pollution in an area in real time. It can be used to inform city planners about where to target their efforts in order to improve air quality.
5. Smart utility meters: Smart meters can be used to monitor the usage of water, gas, and electricity in a city. This data can then be used to improve the efficiency of city services and reduce wastage.
6. Smart parking meters: Smart parking meters can be used to collect data about the availability of parking spaces in a city. This data can then be used to help drivers find a parking space more quickly and reduce congestion.
7. Municipal Wi-Fi: Municipal Wi-Fi networks can be used to provide free internet access to city residents and visitors, making life easier for people living in the city while improving the quality of the city’s services.
8. Intelligent buildings: Intelligent buildings are fitted with sensors that can be used to monitor the use of energy, water, and other resources. This data can then be used to reduce wastage, lower CO2 emissions and create an energy-efficient, environmentally friendly infrastructure.
9. Smart grids: Smart grids are used to manage the flow of electricity around a city. This can be used to help lower stress on the grid at peak hours and significantly reduce the demand on the city’s power supply.
10. High-Efficiency Temperature Controls: High-efficiency temperature controls can be used to regulate the temperature in a city, reducing the demand on the city’s power supply and improving the efficiency of city services.

Which Cities Are IoT Smart Cities?

There are many cities around the world that are using IoT technology to improve the quality of life for their residents. Here are some key IoT smart city examples:

London:

London was one of the first cities to begin using IoT devices to improve city living. In 2010, the city launched a project called the London Internet of Things (IoT) Testbed. This project saw the installation of 1,000 sensors around the city to collect data about everything from air quality to noise pollution. Since launching the IoT Testbed, London has continued to invest in smart city technology. In 2015, the city launched a new project called CityVerve. This project saw the installation of another 1,000 sensors around the city, as well as the deployment of Wi-Fi hotspots, smart streetlights, and smart bins. The data collected by these devices are used to improve the city’s transport network, reduce congestion, and make London a more sustainable city. Westminster’s SmartPark project is another example of London’s commitment to using IoT devices to improve city living. This project saw the installation of smart parking meters in the borough of Westminster. These meters collect data about the availability of parking spaces, which is then used to help drivers find a space more quickly and reduce congestion.
