Smart cities, how the cities of the future are changing

The smart cities until some time ago they were considered the cities of the future. But today there are many examples of smart cities. And they are sufficiently distributed across the various continents to make people talk about a global phenomenon.

It is not easy to clearly delineate the boundaries of smart city concept. But at the same time they exist perimeters and technologies which distinguish smart cities that are very different from each other.

This is the case for example with objects IoT: the devices and sensors ofInternet of Thingswhich allow you to capture and convey information in real time.

What are smart cities

The literal translation of “smart city” And “smart city”. But we often hear about smart cities as city ​​of the future.

In fact there isn’t one unique definition of the meaning of smart city. In fact, smart cities are simply cities that implement various types of technologiesto improve the quality of life of their population.

The term smart city was first associated with Rio de Janeiro: in the early 2010s, the capital of Brazil announced a series of technological investments. And he associated his name withadjective “smart”previously used for various types of devices.

Within a few months the smart city concept would have spread globally. And theEuropean Union would have prepared a spending plan to make some of its most representative cities “intelligent” over ten years.

When we talk about smart cities we often also end up talking about IoT: an acronym that stands for Internet of Things and which refers to various smart devices.

Smart cities use IoT devices to record and analyze large amounts of data in real time

IoT objects are equipped with sensors that capture big data to extrapolate information of various kinds. And who they make use of different types of connectivityto transmit this information in real time.

The IoT sensors it is considered an enabler of smart cities, which now apply technology to more perimeter: from that ofeconomy to that of mobility. Passing through theenvironment and the governance. Until we get to targeted focuses on people and on the quality of theirs vita.

Online collaborative sensors and sensors can be used to measure parameters that are very different from each other: starting from the level of pollution of the air, up to the real-time analysis of the traffic street by street.

In this historical moment various international metropolises they carry forward their personal idea of ​​smart cities. At the same time we tend to categorize at least two macro-models of smart cities: on one side the American one, on the other the Asian one.

What changes between American and Asian smart cities

Il American model Of smart city revolves above all around the axis of research, that of technology and that of globalisation.

The American model on cities that can be considered metropolis or megalopolis: very large cities, or conurbations of different centres, which exceed the monstrous figure of ten million inhabitants.

It is no coincidence that, in this historical moment, precisely the United States count the greatest number of megacities in absolute: ten out of the twenty total spread throughout the world.

Il Asian model of smart city instead it rotates mainly around the axis of the experimentationthat ofautomation and that of the so-called “new town”: new cities characterized by widespread mobility and the availability of heterogeneous services.

The Asian model operates on megacities and even on gigalopoli. And it is promoted both by national governments and private individuals.

What is happening in the cities of the future?

In the previous paragraphs some elements have been defined that allow us to identify the so-called city ​​of the future. At this point, to go into more detail, it will certainly be useful to give one closer look to some of the most popular smart cities internationally.

According to the last one IESE Business School report of Barcelona, London it is the most advanced smart city in the world. On the one hand the capital boasts aeconomy which fears no comparison: capable of contributing around 20%.% of UK GDP.

On the other hand he is using the technology impeccably for years. Today in London the 5G it is highly widespread and allows very fast circulation of large amounts of data.

Data circulation that becomes availability thanks to a remarkable open data policywhich is generating innovation from several points of view: mobility, healthcare e instruction.

In second place New Yorkperhaps the global capital ofInternet of Things. IoT devices are now perfectly integrated in the Big Apple: just think that monitor in real time the quality of all the water in the city.

The smart approach has also been applied to rubbish collectionwith the creation of BigBelly: smart basketspowered by solar energy, which use the IoT to signal the time at which they must be collected.

London, New York, Paris, Berlin, Tokyo and Singapore… These are just some of the best smart cities in the world

The podium of the ranking closes Pariswhich over the last 15 years has managed to reduce consumption and pollution in a surprising way.

Just think that dal 2004 and 2018 the level of issue ofgas greenhouse is decreased by almost 30%. And it doesn’t end here, considering that the French capital aims to reach thetotal elimination of local emissions.

These examples help to understand how different nations are building theirs ideal smart city model. And the list doesn’t end here.

Also Tokyo is aiming for environmental sustainability, investing in hydrogen fuels. And on the construction of hundreds of zero emission buses.

Berlin he bet above all on the concept of mobility-as-a-service, improving its public transport on several levels. While Washington she was an example to her people smart street lights and the choice to disseminate the Wi-Fi.

Honorable mention also for Singaporewhich continues to advance theiniziativa Smart Nation, launched in 2014. And which has invested in a collaborative platform systemwhich enable the free exchange of information between public and private services.
