What Is a Smart City?
The concept of smart cities has been around for some time, but only now are we beginning to see the long-term impact of these initiatives. Beyond saving money for municipalities, smart city projects are improving the quality of life of their citizens.
According to IMD, the organization that publishes the annual Smart City Index, a smart city is defined as “an urban setting that applies technology to enhance the benefits and diminish the shortcomings of urbanization for its citizens.” Some of the technologies that support smart cities include Artificial Intelligence (AI), the Internet of Things (IoT), cloud computing, and 5G connectivity. Together, these technologies help make cities smarter, safer, cleaner, and more inclusive.
We decided to explore some of the smartest cities in the world and the impressive initiatives and future plans they are implementing. Here’s what we discovered.
Hong Kong
Hong Kong measures temperature, humidity, and air quality through smart lampposts and makes this data available to the public through mobile-friendly dashboards displaying images, maps, and information. These smart lampposts are also 5G-enabled.
The city has introduced real-time intelligent traffic signals equipped with sensors that optimize green light timing for both vehicles and pedestrians.
Hong Kong has also invested in an integrated application called HKeMobility, which helps users find the fastest routes using multiple transportation options. It provides travel times, fares, and real-time traffic updates. The application even includes a Senior Mode, offering a more accessible interface for older residents.
Another interesting initiative is iAM Smart, a one-stop platform for digital services that allows users to access multiple services with a single login. All Hong Kong residents aged 11 and above who hold a valid identity card can use iAM Smart.
Singapore
Singapore has consistently ranked as the world’s number one smart city. The city plans to achieve 100% autonomous vehicle adoption on its roads by 2025, but this is just one of its many ambitious goals.
Singapore introduced TeleHealth, enabling video consultations when in-person visits are not possible. At the same time, TeleRehab allows patients to perform rehabilitation exercises from home while IoT devices monitor progress and share data with healthcare professionals.
The city is also advancing robotics solutions aimed at reducing loneliness among its elderly population.
Singapore is widely recognized for its excellence in e-government. Approximately 94% of government services are fully digital from start to finish, supported by a mobile national digital identity and a comprehensive service portal for residents and businesses.
Open data is another key pillar of Singapore’s smart city strategy. The city makes much of its data publicly available through online portals, making it easier for businesses to create innovative digital solutions.
Looking ahead, Singapore plans to establish aerial corridors for drones to transport parcels, mail, and information across the city.
Zurich
Zurich’s smart city journey began with sensors installed on streetlights that automatically adjusted brightness according to traffic levels. Thanks to this initiative, Zurich managed to reduce energy consumption by as much as 70%.
Following this success, the city expanded its network of smart streetlights that collect environmental data and provide public Wi-Fi connectivity.
Smart buildings are also becoming increasingly important in Zurich. Heating, electricity, and cooling systems are optimized to maximize energy efficiency.
Zurich is home to a world-class public transportation system, supported by the Zürimobil mobile app, which provides real-time transit information and alternative transportation options.
The city is also heavily invested in open data and believes strongly in collaborative governance. Several urban projects actively involve different stakeholders in decision-making processes.
Zurich also offers an on-demand transportation service called Pikmi, integrated with the public transport network. Vehicles are booked via smartphone, and passengers traveling in similar directions are automatically grouped into the same vehicle.
New York City
New York City has both the talent and the infrastructure required to become a leading smart city.
As part of a smart city pilot program launched in 2020, hundreds of intelligent sensors were installed to optimize waste management and storage, a major challenge for the city.
These sensors monitored waste levels, making collection routes more efficient. The system also included solar-powered compacting bins capable of holding up to five times more waste than traditional bins.
Traditional phone booths were replaced with smart kiosks that provide public Wi-Fi access and device charging facilities.
To encourage innovation, New York organizes annual competitions that reward solutions making the best use of the city’s open data resources.
Seoul
For Seoul, data is king.
The city analyzes traffic flow, speed, and air quality using sensors and CCTV systems. When unusual temperature, humidity, or lighting conditions are detected, municipal workers or emergency services are immediately notified.
South Korea is one of the world’s leaders in 5G adoption, and Seoul is among the first cities to use 5G extensively for mobility and transportation.
The city also combines LTE mobile network data with public sector information to create what it calls Daily Population Data, which can be used for business intelligence, planning, and marketing activities.
Seoul is actively working to increase citizen participation in public life. Examples include:
Democracy Seoul, a platform for public policy proposals.
M-Voting, a mobile voting system.
Seoul Online Civil Complaints, a platform for reporting and processing citizen requests.
One of the city’s most innovative initiatives is the deployment of OLEV technology, which allows electric vehicles to charge wirelessly while driving. As vehicles pass over charging surfaces embedded in the road, onboard devices convert magnetic fields into electrical energy.
The Seoul Metropolitan Government (SMG) also announced plans to become the first major city to enter the metaverse. The initiative aims to create a virtual environment where citizens can interact through avatars to manage civil complaints and access government services.
London
London has naturally become a hub for Artificial Intelligence innovation, significantly accelerating its smart city ambitions.
The city is home to approximately 750 AI providers, more than twice the number found in Paris or Berlin. London is also one of the few cities with a dedicated Chief Digital Officer.
Londoners are proud to host the world’s largest air quality sensor network, including sensors installed in hospitals, schools, and other priority locations.
However, the city’s data ecosystem goes far beyond air quality monitoring. London maintains more than a thousand open datasets that are used by public organizations, research institutions, and businesses to develop maps, products, and digital services.
Smart parking is also highly developed. Electric vehicle infrastructure and intelligent parking systems help improve air quality and reduce congestion. Parking sensors allow users to check space availability in real time.
The City Hall’s citizen engagement platform has more than 60,000 active members contributing to the development of the Mayor’s strategies.
Dubai
Dubai is rapidly becoming one of the world’s smartest cities.
The city embarked on a seven-year plan to digitize government services, healthcare, education, urban planning, transportation, and many other sectors.
Most of these services are now available through the DubaiNow application. Dubai has also opened access to public data to encourage the development of innovative citizen-focused applications.
Automation has been heavily applied within transportation to reduce accidents caused by driver fatigue.
Another interesting initiative is Dubai Police’s autonomous police stations, where residents can pay fines, report incidents, and access services without direct staff interaction.
Dubai is also pursuing a bold vision of becoming a completely paperless city, with all government transactions conducted digitally.
Cidades e pequenas vilas podem implementar projetos como estes?
Absolutely.
However, becoming a smart city requires strong commitment, long-term vision, and trusted partners capable of guiding decision-makers throughout the transformation process.
If you’re looking for practical inspiration, explore these Smart City projects from around the world that can be easily replicated using City as a Platform. They are designed to be adapted to different territorial realities and municipal contexts.
