Smart Cities: Pioneering Urban Innovations for a Sustainable Future

Smart cities is a new topic for writing an essay and here we will try to define what cities we can call 'smart'? The main factor that defines a city as smart lies in the integration of information and communication technologies that help in operational efficiency, sharing information with the public at many different levels to provide enhanced government service and citizen welfare. In a smart city, the objective lies in the optimization of municipal functions, promoting economic growth and offering high standards of quality of life to citizens through the use of smart technologies and extensive data analysis. In this context, using the technology in optimal ways is the most important part of the process.

A smart city can be defined by considering how infrastructure is based around technology. This allows for environmental initiatives to be implemented, highly functional public transportation systems to serve the population, confident and profressive city plans to be set in motion, and for inhabitants to live and work within the city, depending mainly on its own resources. The success of a smart city relies on the relationship between the public and private sectors as much of the work to create and maintain a data-driven environment falls outside the local government remit. For example, smart surveillance cameras may need input and technology from several companies. Aside from the technology used by a smart city, there is also the need for data analysts to assess the information provided by the smart city systems so that any problems can be addressed and improvements found.

Number of Factors to Define Smart Cities

Firstly, vast amounts of data provenient from a world of interconnected sensors to offer a better understanding of a city’s operations and optimize the use of its resources is key. Smart cities rely heavily on the optimal use of a framework of information that allows for advanced development practices to be put in motion to address urban challenges.

Secondly, the creation of smart and sustainable infrastructure is a vital part of any smart city. With multiple levels of software, user interfaces, communication technologies, and IoT frameworks, smart cities are, by definition, able to offer connected solutions for the public in every aspect of urban living.

Urban mobility, energy usage, health care, shopping, work, construction, and entertainment are a few of the aspects of urban living that are completely revolutionized in smart cities, where citizens are emerged in a connected ‘way of life’ that enhances their everyday experiences.

IoT can be considered the most relevant of all networks within a smart city. The interconnected devices that form an IoT framework in a smart city are constantly exchanging information, from vehicles and home appliances, to drones and on-street sensors. The sea of data that is collected and exchanged is then processed and stored in the cloud, allowing for constant improvements to be made to both public and private sector efficiencies and deliver economic benefits and improvements to the lives of citizens.

In order for IoT to be implemented in a smart city, edge computing is typically used, allowing for only relevant data to be exchanged over the communication network. Another key aspect that we will discuss is data security, where the transmission of data is monitored and controlled to prevent unauthorised access to the IoT network of city’s data platform.

Finally, other technologies that are also employed in smart cities can include:

• Application Programming Interfaces (APIs)
• Artificial Intelligence (AI)
• Cloud Computing Services
• Dashboards
• Machine Learning
• Machine-to-Machine Communications
• Mesh Networks

What to Expect From Cities of the Future?

The combination of multiple technologies such as artificial intelligence, machine learning, high levels of automation and IoT frameworks is enabling smart cities to revolutionize urban living in many ways. As we have seen, the central idea behind smart city living is to enhance quality of life for citizens, so now, let’s have a look at what we can expect in smart cities.

Mobility is one of the central issues in urban environments. In smart cities, intelligent traffic management systems are able to monitor traffic flows and optimize traffic lights to reduce congestion. Smart parking assists drivers in locating free parking spaces, as well as enabling digital payment. Finally, ride-sharing can also be integrated into smart city infrastructure to optimize rides both in regards to timings and financially.

Environmentally friendly solutions for urban centers are also at the top of the priority list for improving city life. Combating climate change and environmental impact is most certainly one of the central discussions faced by humanity today. Smart cities support this by minimizing and monitoring air pollution, implementing smart waste and sanitation management solutions that enable internet-based trash collection, smart bins and fleet management systems.

Energy efficiency and conservation solutions such as dimming street lights in empty roads can be expected in smart cities. Smart power grid technologies are a significant step towards smarter cities, enabling improvements in power distribution, operations and maintenance.

Safety and security are always extremely important points to take into account when considering city life. In smart cities, continuous monitoring with cameras, sensors and drones drastically reduces crime rates, as well as providing emergency response teams with anticipated warning on events such as floods, landslides, hurricanes or droughts.

Construction in smart cities is also greatly optimized, from urban planning to maintenance. Buildings in smart cities can be equipped with sensors to provide real-time insight into maintenance requirements, before disasters occur. Drones can also provide regular structural surveys of all kinds of buildings in smart cities, where this can also include infrastructural features such as power lines, water and gas pipes.

In addition, the unity of these technologies can also benefit other activities such as manufacturing, urban farming, and many, many more. In all, it is safe to say that life in a smart city is greatly enhanced by the integration of technology-enabled physical infrastructure, IoT frameworks and cloud computing and processing power. With this, citizens can benefit greatly from improvements in all sectors of urban life.

Practical Analysis of Smart Cities Function

In order to truly comprehend how smart cities function, we need to understand the four steps that are put in place to improve quality of life for citizens and stimulate economic growth. This is carried out by the implementation of a network of IoT devices along with other technologies such as edge computing.

Firstly, a world of interconnected sensors gathers vast amounts of real-time data on just about anything that happens in a smart city. This allows for valuable insight to be extracted from this data in both real-time, and in later stages. Secondly, data analysis is crucial for the extraction of these insights. This enables citizens, companies and authorities to obtain valuable information on the operation of city services, mobility, and even household appliances. Thirdly, communicating and exchanging these insights creates a well informed web for both citizens and decision makers, essentially democratizing city policy and generating what is known as e-governance. Lastly, action can be taken to improve operations, manage assets and improve the quality of city life for the residents.

In all, this smart network of sensors and devices enables citizens and decision makers to engage with real-time data from a multitude of connected assets. This allows whole populations to interact with smart ecosystems, gaining access to infrastructural insights from the city, which in turn allows for cost cuts, enhanced sustainability, optimized power consumption and waste collection, improved air quality and reduced congestion.

Geopolitical Importance Due to Current Population in the World

With over 54% of the world population currently living in urban environments, people around the globe are constantly migrating to cities. By 2050, this figure is expected to be over 65%, by which point an additional 2.5 billion people will be urban citizens, reiterating the challenge of managing social, environmental and economic sustainability in urban centers. In short, smart cities enable both citizens and authorities to collaborate in the development of initiatives that use smart technologies to ensure the optimization of resources and the improved management of assets to cope with the urban population increase. Reduced infrastructural costs, high quality of life and economic growth can be considered three main pillars of smart cities in a geopolitical aspect. The importance of these factors is pivotal, especially when considering the enormous population growth that is expected in urban centers in the next three decades. As well as this, improvements made to current infrastructure can also add value to these existing structures, generating new revenue streams and operational efficiencies to help save money for governments and citizens alike. With sustainability being a crucial aspect in urban centers, improving the efficiency of resource usage and creating smaller geographical footprints is key. Smart technology can help alleviate the negative impacts of urbanization, such as fossil fuel use. This is made possible with the implementation of an electric transport system to reduce emissions. Electric vehicles could also help to regulate the frequency of the electric grid while not in use. Such sustainable transport options should also see a reduction in the number of cars in urban areas as autonomous vehicles are expected to reduce the need for car ownership amongst the population.

Redistributing Labor and Opportunities of Smart Cities

A positive impact on formal employment can be expected in smart cities. Even though smart technologies will substitute a number of administrative and field jobs, they will also generate maintenance, operational, temporary installation and many other demands for work, with e-career centers and data-driven formal education enhancing a city’s pool of skills. Additionally, the process of digitizing government functions such as business licensing, permitting, and tax filing can free local enterprises from red tape, contributing to a more entrepreneurial business climate.

In the housing sector, the de-bureaucratization and digitization of land acquisition, design, approval and permitting, can mitigate risks and delays and, ultimately, boost construction in smart cities. Additionally, open-source databases for land that can potentially be developed will assist constructors in identifying idle pieces of land, optimizing operations for the sector. Other areas of the market which are positively affected by the implementation of intelligent cities are utilities, health care, and mobility, where jobs will also be redistributed, with retraining programs being put in place to prepare workers for new technologies. In the infrastructural sector, a combination of traditional construction and smart solutions results in a more dynamic response to changing demands, where capital-intensive and long term planning gives way to more flexible, adaptable methods. For instance, if population growth surges in a far-flung neighborhood, adding a new subway or bus line with the accompanying fleet expansion may take years. By contrast, a privately operated on-demand minibus service could be up and running much faster.

Conclusion

With this in mind, it is safe to say that in smart cities, city governments can collaborate with the private sector extensively in funding public service initiatives, creating dynamic partnerships that aid the city in providing citizens with public goods with more speed and efficiency. As well as funding, adding more actors to the game also opens the door to more creativity, resulting in new and efficient public service solutions being created. In this context, when private-sector innovations spring up organically, the government will regulate, convene key actors, offer subsidies, or change purchasing decisions. Rather than taking a master-planning approach, smart cities will cultivate ecosystems that offer consortia and even physical collaboration spaces. Although starting transformations in a city towards more intelligent structures can be easier when inherent advantages such as wealth, density and existing high-tech industries are present, less privileged cities can also achieve. With a combination of vision, efficient management, the will to surpass conventional methods and a mindset that puts residents at the center of all priorities, any community can empower its individuals to shape the future of the cities they call home.
