What is a Smart City?
A “Smart City” is the concept of using modern technologies such as the Internet of Things (IoT), Artificial Intelligence (AI) and Machine Learning (ML) to make cities and towns more efficient and sustainable in regards to the environment, society and economy. They try to solve problems related to the increasing population, health, climate change, pollution, housing, work, and living conditions.
Advantages of a Smart City
There are numerous advantages to the implementation of a smart city with modern technologies that can benefit its citizens and the environment to a large extent.
Sustainable Usage of Resources
Smart cities improve the usage of resources such as electricity or water by predicting their demand. Thanks to sensors that are installed inside commercial and residential buildings, like smart meters, central management systems can analyse the amount of energy consumed. This data can then be analyzed to predict patterns and demand, thus limiting wasted resources.
In addition, air quality sensors, renewable energy sources, and green spaces improve the urban environment even more.
Transportation can be made more efficient by using connected traffic management systems and new types of mobility. Trains, trams, buses or taxis can inform citizens of precise arrival times and delays. This means that people will waste less time waiting for transportation.
Another advantage is the development of new types of mobility such as shared vehicles (cars, bikes, e-scooter). They can help to reduce the number of cars on the street and improve the flow of traffic.
Infrastructure, such as streets, bridges and buildings can be made safer and cheaper to keep running. With sensors installed throughout the structure and AI data analysis, maintenance issues can be predicted even before they occur. These problems can then be repaired or rebuilt without any serious damage happening to the infrastructure or even the citizens.

A smart city will be a safe place to live in. Intelligent lighting systems will help to keep unsafe areas like parks, train stations, or side streets bright in order to reduce the likelihood of criminal activities.
Also, smart cameras and CCTV are always keeping an eye on the public. In combination with face recognition and AI image processing, they are able to alert the police, fire department or police when recognizing an incident.
More Efficient Public Services
Public services can be digitized and made more efficient. There will be no need to go to any governmental offices to request documents or services. One example is the issuance of land titles by using blockchain technology. Blockchain is able to make this process safer and faster by storing the information on a decentralized database that cannot be manipulated.
More Job Opportunities
With new technologies, skilled people are needed to run and implement the smart city. This will allow for more job opportunities to arise and unemployment rates to lower. Another factor is the improved network and internet connection which helps more people to have access to resources for education and work.
Disadvantages of a Smart City
Despite the fact that the advantages have a high impact on an urban area, a smart city also comes with some downsides that should not be ignored.
An important issue for a smart city is the secure management of sensitive information. In order to make efficient decisions and predictions, many different types of information have to be collected. Whether it is building data like energy consumption and occupation, or personal data such as CCTV recordings and travel information.
In order to gain trust from its citizens, the local government of the smart city has to prove that they are able to handle this information with the highest level of security. They also need to be able to withstand any type of cyber attack.
Privacy and Social Control
Privacy is also a big concern since data is being collected about a person by security cameras and information is shared about private buildings. It is also important who is handling the private data, as this authority might have much control over public opinions and decisions.
Early-Stage Business Models
Most companies that are operating in the smart city sector are still relatively new. That’s why some business models are not tested sufficiently or have not shown the ability to generate profits. Even though many cities are funding these startups with high amounts of capital, it is necessary for them to create a business that can sustain the future.
Lack of Skilled Workers and Professionals
In order to run the smart city, skilled workers and professionals are required. Since most of these new technologies just came to market, there are still not enough people available. Training and educational programmes have to be made available in order to share knowledge with potential employees but also the local government and even its citizens.
Many buildings have to be renovated or refitted with IoT sensors and a high-speed internet connection. Public transport and infrastructure need to be equipped with smart technology as well in order to make the concept of a smart city work. All of these improvements will come at a high cost and cities need to be aware of what is necessary to really transform their urban area.
The Top 3 Smart Cities and Why They Succeeded
There are a number of cities that put a large focus on smart technologies. They are able to achieve great progress and benefit citizens, as well as businesses.
We will take a closer look at the top three smart cities, to show how the advantages but also disadvantages are applied to the real world. According to the IESE Cities in Motion Index from 2022, the current smartest cities are London, New York, and Paris.
In the following section of this article, you will understand how these cities work, why they are smart, and how they became so successful.
1 | London, United Kingdom
London is the capital of the United Kingdom and also the smartest city in the world.
It was able to gain the top spot thanks to a thought-through strategy that focuses on every aspect of a smart city. Sadik Khan, the mayor of London, has created the “Smarter London Together” initiative that provides aims and requirements for a smart city.
A large focus lies on improving the traffic system of the city, as well as decreasing congestion. Some technologies that have been implemented already are the congestion charge, contactless payment, and an ultra-low emission zone. Cameras and sensors are used to collect the data to control the cars entering these specified zones.
To encourage walking in the city, an app was launched to showcase walking routes throughout London. The overall goal is to have 80% of journeys by foot, bicycle, or public transport
Additionally, London promotes businesses that engage in the smart city sector. A large amount of city data is available for use to develop new solutions and technologies.
2 | New York City, United States
Another major city that has invested a lot in smart technologies is New York. It is by far the most populated city in the United States and therefore must solve a lot of problems and challenges.
One major problem is the environmental sustainability and health of citizens. To improve this aspect, new york launched the Smart Cities Programme. Over 600 government buildings have been upgraded with LED lighting systems to save energy. Furthermore, smart meters were installed in numerous residential and commercial properties to control and maintain a sustainable level of water consumption. In case a leakage might appear, the sensors can inform local residents.
To improve the city even more, air-quality sensors are placed throughout New York to monitor and improve the air. This technology works hand-in-hand with a traffic control system that optimizes the flow of cars, public transportation, and other participants.
Similar to London, an initiative has been launched to fund businesses that are working in the smart city sector. The Smart Cities Innovation Partnership supports new technologies that can improve the city with up to $1 million.
3 | Paris, France
The third smartest city in the world, according to the IESE Index, is Paris.
France’s capital has progressed towards a smart and sustainable metropolitan area. Especially due to the lack of green spaces, low air quality, and high congestion, a change was more than necessary.
To improve air quality, electric cars are being promoted, as well as the use of public transportation. An induction charging system has been tested by Renault to make the process of charging cars easier and more convenient. In addition, Paris is set to be transformed into a 15-minute city. This means all essential amenities and services can be reached by a walk of 15 minutes.
Paris has also upgraded their traffic management system and wants to make the city greener. They created the largest urban farm and are planning to make space for more parks, as well as roof gardens.
A smart city offers many advantages to its citizens, nature, as well as the economy. Modern technologies will be able to make it safer, healthier and more sustainable to live in an urban environment.
But while it sounds good at first sight, there are some negative aspects that are important to keep in mind. Privacy will be largely affected by it and since it is quite a new concept, many business models are not yet proven to work. In addition, there is still a lack of skilled workers and knowledge.
