The intelligence of a smart city is based on the desire to reconcile ecological, economic and technological initiatives, where people, whether they are citizens, entrepreneurs or local elected officials, all become major players. The concept of smart cities is primarily about to slow down the evolution of global warming and to limit the use of natural resources, especially electricity consumption. This is why resilience and sustainability are the key words in smart city governance, a notion that generates many concrete examples.
The main use cases for the smart city
If the permanent mobility of people and goods characterizes the modern world, it is necessary to combine smart city and clean transport. This is why, in a smart city, data governance requires the implementation of high-performance infrastructures, resulting from cutting-edge innovation, without losing sight of the environmental issue. The task is tough for the smart city, with water, energy and air management as its battle horse, on a limited territory and subject to an ever-increasing demography. Fortunately, this necessary struggle can lead to great victories, with :
- connected systems, to detect in real time bicycles, pedestrians and vehicles in traffic;
- sensors for remote reading of water meters, in order to identify consumption peaks;
- warning devices in case of power failure, for a permanent control of the public lighting;
- smart probes, in charge of providing information on indoor air quality, in addition to quantifying air pollution in the streets;
- water level and quality measurement equipment to anticipate flooding and contamination risks.
4 examples of smart cities and their specificities
As you can see, the smart city has the characteristics of a metropolis that is keen to use the advantages of the latest technologies to offer its users a pleasant, sustainable living environment and to meet the challenges of anti-pollution. Although the smart city has its advantages and limitations, its expansion is taking off all over the world, as in :
- Nice, which is experimenting with the massive integration of renewable energies in its building and transport management;
- Zurich, and its remarkably efficient IoT infrastructure;
- Singapore, known for its high level of digitalization, is conducive to dialogue and active participation of residents in city projects;
- Barcelona, with its ubiquitous LED sensors, for traffic and noise monitoring.
