Abstract

The pervasive influence of Information and Communication Technology (ICT) has significantly transformed the global landscape, emerging as a pivotal element in ensuring safety and security. According to the 2017 United States Census Bureau, the anticipated world population is projected to reach 8.5 billion by 2030, with further estimates indicating an increase to 9.8 billion by 2050 and 11.2 billion by 2100. Presently, over half of the global population resides in urban areas, witnessing a substantial influx of rural migrants seeking enhanced opportunities, education, and an elevated quality of life. Cities are grappling with the challenge of accommodating this unprecedented surge, surpassing their infrastructural, security, and service capacities. Consequently, urban centers are compelled to enhance living standards by expanding their capabilities. This requires adopting contemporary ICT methodologies, transforming cities into Smart Cities. These cities efficiently assimilate new residents, improving the overall quality of life through cutting-edge technologies such as smart homes, intelligent energy grids, sophisticated retail systems, and the Internet of Things (IoT). This paper explores Smart Cities, examining prospects and challenges. It delineates fundamental components crucial for their realization, offering insights to guide governmental decision-making in initiating Smart City projects.

1. Introduction

According to Bakici, Almirall, and Wareham, smart cities represent urban environments leveraging communication technologies to enhance the well-being of their citizens and fortify a resilient development framework. A smart city is characterized by advancements in governance, mobility, infrastructure, and overall quality of life, achieved through a synergy of citizen engagement, environmental stewardship, and the strategic deployment of Information and Communication Technology (ICT) tools.

In essence, a smart city strategically employs a scalable, robust, and secure ICT infrastructure [1] to elevate the quality of life for its residents. This multifaceted approach encompasses several key objectives:

• Fostering economic growth by generating employment opportunities within the community.

• Safeguarding public safety, health, and educational resources.

• Implementing sustainable energy practices that meet present demands without compromising future needs.

• Streamlining smart mobility, energy, and water infrastructures for seamless and continuous operation.

• Establishing proactive measures and responses for natural catastrophes and rapid incidents.

• Crafting governance policies aligned with contemporary legal frameworks.

However, the pursuit of smart city development introduces a new set of challenges, including but not limited to insufficient resources, traffic congestion, and environmental degradation. The ensuing discussion will delve into the complexities and intricacies of smart city implementation, elucidating both its promises and impediments [2].

The depiction of a smart city is illustrated in the accompanying diagram (Figure 1).

Figure 1.

A smart city [3].

Information and Communication Technology (ICT) offers reliable solutions to the challenges faced by urban areas, offering cost-effective and user-friendly alternatives.

Smart cities have the potential to bring numerous benefits to residents. For instance, the implementation of intelligent transportation systems holds the promise of mitigating traffic congestion and reducing air pollution. The integration of smart energy grids can lead to energy savings and cost reduction. Likewise, smart water systems have the capacity to conserve water resources and promptly identify leaks. Implementing smart waste management systems can contribute to waste reduction and enhance sanitation. Furthermore, the adoption of smart public safety systems is anticipated to decrease crime rates and improve emergency response times. Smart healthcare systems hold the potential to enhance access to healthcare services and cut down on costs. Additionally, smart education systems can offer personalized learning experiences, thereby improving student outcomes.

The concept of a smart city revolves around the deployment of pervasive communication technologies and intelligent devices aimed at enhancing urban environments and fostering development [4]. In this framework, the notion of a smart city can be categorized into four distinct levels, as depicted in the Figure 2.

Figure 2.

Four layers of smart city (Xu, 2012).

In this concept, these four levels, according to Xu, interact with one another. The Sensor layer collects and accumulates information and data in real-time, allowing data handling in the following layer to be more efficient. To acquire data, the Sensor layer frequently employs cameras, RFID, and detectors.

The Network layer comes next, and it is in charge of data and information interchange and transit. The most often used network layer channels are the internet, telephony networks, and television networks. Following this layer is the Platform layer, which incorporates information processing and management via platforms such as business support, network, and cloud computing platforms. The last layer is the Application layer, which allows users to interact with smart services based on data collected in the smart city [5].

Figure 3 depicts the many schemes of a smart city’s technical architecture. These schemes interact with one another through actors (Service Providers, Municipal Departments, and the general public). The Sensor and Network layers form the foundation of the infrastructure (Figure 3).

Figure 3.

Smart city actor’s interactions [6].

A flowchart of interactions between citizens, governments, and other service providers in a smart city is shown in Figure 3.

Citizens are the end users of smart city services, and they interact with the city through a variety of channels, such as mobile apps, websites, and in-person services. They can use these channels to access information about the city, report problems, and provide feedback.

Municipalities are responsible for planning, implementing, and managing smart city services. They interact with citizens to collect feedback and identify needs, and they work with other service providers to deliver integrated solutions.

Other service providers include businesses, utilities, and non-profit organizations that offer a variety of services to citizens, such as transportation, energy, and healthcare. They interact with municipalities to share data and collaborate on smart city initiatives.

The diagram shows how these three groups of actors interact with each other to create a smart city. For example, citizens can use a mobile app to report a pothole to the municipality. The municipality can then use this information to dispatch a crew to fix the pothole. Or, a utility company can use data from smart meters to identify areas where energy consumption is high. The utility company can then work with the municipality to develop programs to help citizens reduce their energy consumption.

Smart city actor interactions are essential for the successful development and implementation of smart city initiatives. By working together, citizens, municipalities, and other service providers can create a more efficient, sustainable, and livable city for everyone.

Here are some additional details about the interactions between the three groups of actors in the diagram:

1.1 Citizens and municipalities

Citizens can use smart city apps to report problems to the municipality, such as potholes, graffiti, or broken streetlights.

Citizens can also use smart city apps to provide feedback on city services and to participate in surveys and polls.

The municipality can use data from smart city sensors to monitor traffic conditions, air quality, and other environmental factors.

The municipality can use this data to make better decisions about how to manage the city.

1.2 Municipalities and other service providers

Municipalities can share data with other service providers to improve the efficiency and effectiveness of city services.

For example, the municipality can share traffic data with a transportation company to help the company improve its bus routes.

Municipalities can also work with other service providers to develop new smart city initiatives.

For example, a municipality might work with a utility company to develop a smart grid that can manage energy consumption more efficiently.

1.3 Other service providers and citizens

Other service providers can use smart city technologies to offer new and improved services to citizens.

For example, a utility company can use smart meter data to offer customers personalized energy-saving tips.

A transportation company has the opportunity to leverage smart city applications for offering real-time updates on bus arrival schedules and enabling customers to conveniently pay for fares using their mobile phones.

The interactions among key players in smart cities are intricate and diverse, playing a pivotal role in the success of smart city initiatives. Collaborative efforts between citizens, local authorities, and various service providers are crucial in shaping a more promising future for everyone.

Illustrated in Figure 4, cities are segmented into five layers of application: City resources, services it provides, social policies, infrastructural designs, and the surrounding environment. Each layer is further categorized (refer to Figure 4) [5].

Figure 4.

Application layers in smart cities [7].

The image represents a layered model of a smart city, highlighting the various interconnected components that contribute to a sustainable and thriving urban environment. It emphasizes three primary pillars: economy, environment, and social, each supported by a set of application layers.

1.3.1 Economic pillar

Administration and Economic Actors: This layer focuses on the governance structures, financial institutions, and businesses that drive economic growth and development.

1.3.2 Environmental pillar

Resources and Managerial Infrastructures: This layer emphasizes sustainable resource management, including energy, water, and waste, through efficient infrastructure and technologies.

1.3.3 Social pillar

The diagram illustrates how these pillars are interdependent, demonstrating that smart city initiatives can simultaneously address economic, environmental, and social concerns. By investing in interconnected solutions that tackle these interrelated challenges, cities can create a more sustainable and equitable future for their residents.

A more straightforward representation of an urban system is depicted in (6), comprising three main components, with the smart city component interconnected through Information and Communication Technology (ICT) (refer to Figure 5) [9].

Figure 5.

Application layers in smart cities [8].

The illustration depicts a schematic of the three pillars of smart city sustainability: economics, environment, and social. A number of application layers support each pillar:

Administration and economic actors in the economy.

Resources and managerial infrastructures in the environment.

Social: education and culture.

The graphic also demonstrates how the three pillars are interrelated and how smart cities must aim for balance between them.

Smart city projects, for instance, may stimulate the economy by drawing in firms and creating employment. Through the reduction of pollutants and energy consumption, they can also contribute to environmental protection. Additionally, by improving access to healthcare and education, they can contribute to strengthening the city’s social fabric.

The following are some instances of smart city applications that correspond with each of the three pillars:

1.3.4 Economy

Although they are still in their infancy, smart cities have the potential to have a profound effect on people’s lives all over the world. We can make our cities’ economies, environments, and social fabrics better with the help of technology, giving everyone a more sustainable and livable future.

2. Objectives

Urban centers wield significant influence over social, economic, and environmental factors, necessitating a focused approach towards three primary goals.

2.1 Energy resource management through the internet of energy (IoE) concept

Efficient management of energy resources is pivotal, guided by the principles of the Internet of Energy (IoE). This entails leveraging interconnected technologies to optimize energy consumption, enhance sustainability, and foster responsible resource utilization.

2.2 Safety and security enhancement

The second goal centers on bolstering safety and security within the urban landscape. This encompasses the strategic deployment of Closed-Circuit Television (CCTV) systems, automated alert systems for residents, detection of anomalous activities, and the provision of real-time information updates as needed. The overarching objective is to create a secure environment for residents.

2.3 Transportation efficiency and environmental preservation

The third goal focuses on improving transportation systems and safeguarding the environment. This involves initiatives to reduce pollution levels, implement energy-efficient street lighting, and mitigate traffic congestion, contributing to a sustainable and eco-friendly urban ecosystem.

2.4 Advancement of educational facilities

Recognizing the critical role of education, there is a need for increased investment to ensure equal opportunities. This encompasses the facilitation of continuous learning through online and remote education modalities, as well as the integration of smart technologies in traditional classrooms.

2.5 Tourism development

Cities aim to harness their inherent resources to attract a greater influx of tourists, thereby contributing to economic growth and cultural exchange. Strategic development initiatives are undertaken to showcase the unique attractions and offerings of the urban landscape.

2.6 Healthcare enhancement for citizens

Embracing new technologies, particularly in the realm of healthcare, is integral to improving the well-being of citizens. This involves leveraging technological advancements to enhance healthcare accessibility, ensuring that citizens have access to proper and timely medical services.

3. Implementation and deployment

A consortium of experts spanning diverse disciplines is essential for the strategic delineation and implementation of smart city initiatives. This interdisciplinary assembly comprises professionals in Economics, Sociology, Engineering, Information and Communication Technology (ICT), and Policy and Regulation. Their collective expertise is instrumental in addressing challenges inherent in routine urban management and crises, including pandemics.

The impetus behind formulating robust urban transformation strategies and ensuring an unbiased selection of experts — individuals devoid of political affiliations — for pivotal roles in policymaking, decision-making, and implementation teams is twofold. Firstly, it stems from the intricate nature of smart city dimensions and the requisite systemic approach, which demands multifaceted skills. Secondly, it acknowledges the specific capacities and tools imperative for effective realization of smart city concepts.

To streamline the identification and assessment of these experts, a groundbreaking hybrid competency assessment model has been proposed. This model integrates fuzzy logic and a neural network, forming a technological framework to evaluate the competencies of specialists. It takes into account the impact of human factors on personnel selection processes and overall system management.

Complementing this innovative model is a web platform named “Smart City Concept Personnel Selection.” This platform, designed with adaptability in mind, caters to municipal or regional institutions. It facilitates transparent and merit-based selection of qualified personnel, ensuring effective decision-making and judicious utilization of public funds in both routine and emergency scenarios, exemplified by its applicability during crises such as the COVID-19 pandemic (Figure 6) [10].

Figure 6.

Fuzzy model assessment algorithm for specialist competence [10].

The algorithm has two main steps: The first step involves identifying the key criteria that are important for assessing the competence of specialists for a particular task or role. These criteria can be quantitative (e.g., years of experience, number of publications) or qualitative (e.g., communication skills, problem-solving skills). Once the criteria have been identified, they are then converted into fuzzy variables. This means that each criterion is assigned a membership function, which defines the degree to which a specialist satisfies that criterion. The second step assesses the experts’ competencies. This step involves using the information models of criteria to assess the competencies of specialists. This can be done using a variety of methods, such as questionnaires, interviews, and performance assessments. Once the competencies of each specialist have been assessed, they are then assigned a fuzzy score for each criterion, and based on the score they are selected.

There are a few other frameworks proposed by academic and industrial sources that illustrate smart cities’ architecture. Among the numerous models put forth, the one advanced by the US National Institute has gained widespread adoption. Characterized as a complex system, often denoted as “A system of systems,” a smart city encompasses diverse entities, including individuals, infrastructure, and process components. The model endorsed by the US National Institute identifies six fundamental components integral to a smart city: Environment, Quality of Life, Citizens, Transport, Economy, and Government.

As highlighted in a 2014 report from the European Parliament Policy Department, 34% of European smart cities incorporate only one of the aforementioned components, emphasizing the diverse configurations within smart city implementations. The evaluation of smart cities from a comprehensive standpoint involves various approaches. Noteworthy perspectives include the integration of an urban Internet of Things (IoT) system, considerations of urban environments, assessments of competitiveness, and evaluations of resilience.

However, to attain an optimal smart city configuration, the integration of several fundamental components is imperative. This integration ensures a holistic and synergistic approach, facilitating the realization of a smart city that effectively addresses the multifaceted challenges and opportunities inherent in urban environments.
