Presently, more than 50 per cent of the world's population lives in cities, and according to The World Bank, the global urban population will increase by 1.5 times by 2045—from 4 billion to 6 billion urban residents. The increasing population in cities means more people to transport, more children to educate, and more citizens to provide services for. To address all of these burgeoning issues, the idea of a smart city was born.
Smart cities are urban municipalities leveraging information and communication technologies (ICT), such as data analytics and the Internet of Things (IoT) to provide solutions for city residents. The goal of developing smart cities is to make urban life more enjoyable and efficient, sustainable, and interconnected by leveraging automation technologies and data-driven solutions to enhance various aspects of infrastructure, services, and quality of life. And while there are no fixed figures as to how many smart cities are there in the world today, there's no doubt that a lot of city governments are already taking action, preparing their city for the future by adopting smart city tech.
What does it take for a city to become 'smart'? In this article, we'll explore the fundamental components that contribute to the transformation of urban areas.
1. Digital infrastructure and connectivity
The foundation of every smart city is a robust digital infrastructure that can support new innovative city-wide tech solutions. Smart cities require high-speed internet access, redundant broadband networks, wireless connectivity, data centres, and more to deliver improved services to their constituents.
To address these needs, cities should consider advanced solutions like satellite internet and the adoption of 5G mobile networks. These new internet access technologies enable seamless and uninterrupted communication and data exchange.
Indeed, from sensors monitoring air quality to smart grids optimising energy distribution, digital infrastructure forms the foundation of smart city initiatives.
2. Urban mobility and transportation
Efficient public transportation systems are essential for moving a mass number of people from point A to point B. For this reason, Smart cities leverage technology such as smart traffic systems and smart metro systems to transform mobility. With real-time traffic monitoring and intelligent public transportation networks, for example, commuting throughout the city is made easy for residents and travellers alike.
What's more, sustainable mobility options such as electric vehicles and bike-sharing programs provide eco-friendly alternatives for transportation. With zero emissions and a near-silent operation, these alternative vehicles minimise noise and air pollution. Indeed, smart transportation systems can enhance connectivity and reduce congestion by prioritising accessibility and sustainability. In the end, cities will be more accessible and liveable for everyone.
3. Public safety and security
In an urban environment, safety and security are always an issue for inhabitants. With technologies such as advanced video surveillance systems, coordinated emergency response, and predictive policing algorithms, a smart city can address concerns involving personal safety and criminality.
In proactively addressing crime and emergencies through the use of data analytics, cities can create safer communities and foster peace of mind among residents.
4. Public health services
Smart cities prioritise the well-being of their citizens by leveraging technology to deliver public health services more efficiently and effectively. Telemedicine platforms, for example, connect patients with healthcare providers. Meanwhile, data-driven solutions enable targeted interventions to address public health challenges, such as during epidemics and pandemics, where contract tracing is key to preventing further spread of the disease.
By leveraging technology to promote health equity and access to care, smart cities empower individuals to lead healthier lives.
5. Environmental and resource management
Environmental sustainability is arguably the core of smart city development. From waste management initiatives to renewable energy adoption, smart cities employ innovative solutions to minimise their environmental footprint and promote resource conservation.
By investing in green infrastructure and embracing circular economy principles, cities can mitigate the impact of climate change, minimise anthropogenic activities' impact on the biosphere, and create more resilient urban ecosystems for future generations.
6. Transparency in governance and citizen engagement
Transparency and citizen engagement are essential pillars of smart governance. In some smart cities, digital platforms were built to encourage citizens to participate in decision-making processes. Meanwhile, open data initiatives promote accountability and transparency in government. This eliminates the need to go through tedious processes just to obtain government that should be available to the public, such as accounting of government projects.
By fostering a culture of collaboration and inclusivity, smart cities can harness the collective intelligence of their citizens to address urban challenges and drive positive change.
The development of smart cities represents a shift in urban planning and governance. Cities can overcome the challenges of the 21st century and create more sustainable, inclusive, and resilient urban environments by welcoming technology and innovation. As decision-makers and city leaders chart the course for the future, they must prioritise the core components of smart city development, laying the foundation for cities that are not only smarter but also more vibrant, equitable, and prosperous.
