1. Introduction
The city of Novi Sad, which was awarded the title of European Capital of Culture in 2022 (ECoC), is rapidly developing and becoming an ideal location for the implementation of innovative smart city solutions [
1]. This status allows the city to integrate cutting-edge technologies, not only enhancing infrastructure but also raising public awareness of the benefits that smart cities offer, such as more efficient urban services, improved traffic solutions, and sustainability [
2,
3]. The development of digital services and smart mobility further contributes to making Novi Sad a model of sustainable urban development [
4]. Mohanty [
5] emphasizes the pivotal role of information and communication technologies (ICT) in improving urban infrastructure and efficiency. Technologies such as the Internet of Things (IoT) and big data analytics enable cities to manage resources more effectively, enhancing sustainability and reducing environmental impact [
6]. In the context of Novi Sad, the successful application of these technologies may depend on how willing citizens and local authorities are to embrace new technologies [
7]. In the context of the aforementioned discussion, the following hypothesis is proposed:
H1. The acceptance of new technologies (ANT) has a positive and significant impact on the level of use and integration of smart city solutions.
Key aspects of smart city development include smart infrastructure, advanced transportation systems, energy efficiency, and innovations in healthcare, all aimed at improving quality of life and reducing environmental burdens [
8]. These components enable cities to become more sustainable and better suited to long-term urban development, particularly in response to increasing population demands for resources [
9]. For instance, digital networks and the Internet of Things (IoT) enable better coordination and resource management, leading to greater efficiency in city operations [
10]. Conversely, Augusto [
11] highlights that the integration of digital technologies, particularly in data management, plays a crucial role in achieving sustainability in urban areas. He emphasizes that technological solutions alone are insufficient if citizens are not involved in the process or aware of the benefits these technologies can bring to everyday life. Therefore, awareness of smart solutions becomes essential for successful integration. Yin et al. [
12] and Wu et al. [
13] suggest that a high level of citizen awareness about the technological advantages of smart cities is necessary for the successful implementation of these solutions. When citizens understand how technology can directly improve their quality of life, such as reducing traffic congestion or increasing energy efficiency, they are more willing to adopt and use these technologies. On the other hand, Azevedo Guedes et al. [
14] point out that the long-term integration of smart solutions relies on continuous awareness-raising, which increases citizen engagement.
Haque et al. [
15] and Sorri et al. [
16] argue that continuous education about smart technologies is a significant factor in achieving sustainable cities. They assert that without adequate awareness, even the most innovative technological solutions will not reach their full potential. Similarly, Ullah et al. [
17] suggest that citizen engagement and active participation in these solutions are critical for the long-term success of smart city projects.
H2. Awareness of smart cities (ASC) positively influences the level of use and integration of smart city solutions.
Tamariz-Flores and Torrealba-Meléndez [
18] investigate advanced vehicle systems in smart cities, particularly emphasizing how digital technologies enhance the efficiency of urban transportation and reduce traffic congestion. Their research shows that these systems, when integrated with city infrastructure, contribute to safety and sustainability, while also improving the overall functionality of transport networks, which is crucial for achieving sustainability in smart cities. Linking these technologies with citizens’ everyday needs proves to be key for the efficiency of city services. In contrast, Aihara and Law and Linch [
19] highlight a participatory approach through which citizens can directly engage in managing city resources via crowdsourcing platforms. This engagement leads to better resource allocation and improves the quality of life, especially in developing cities. Active citizen participation increases their willingness to accept and utilize advanced technologies, accelerating the implementation of smart solutions [
20,
21]. Amine [
22] draws attention to the energy efficiency of smart technologies as a key component of sustainable urban development. His research demonstrates that resource optimization through these technologies helps cities become more resilient to environmental challenges. ELKheshin and Saleeb [
23] emphasize that effective resource management is critical for long-term sustainability, not only in urban areas like Novi Sad but also more broadly. Ringel [
24] underscores that technologies must be adapted to the specific needs of local communities. This is particularly important for cities in the process of developing smart solutions, where local challenges and needs can shape the direction of development. On the other hand, Berawi [
25] and Campisi et al. [
26] argue that smart cities are successful only when technological innovations are integrated into key urban sectors such as transportation, energy, and healthcare, optimizing resource use and improving service delivery efficiency. The key to the success of these technologies lies in citizens recognizing their benefits. When digital services are utilized in everyday life, the level of acceptance and integration of smart solutions increases, ensuring greater efficiency in urban systems. In this context, Fadhel et al. [
27] point out that different approaches to data fusion in smart cities enable more efficient technology applications and real-time resource optimization. The Internet of Things (IoT) plays a crucial role in connecting various sectors, from transportation to energy, further contributing to the sustainability and efficiency of smart cities [
28].
H3. Engagement in the use of digital services (EUDS) positively influences the level of use and integration of smart city solutions.
The development of smart cities depends on various factors, including innovation and technological advancement, but also social inclusion and sustainable leadership [
20]. While cities such as London, Singapore, and Barcelona demonstrate successful examples of renewable energy applications, their approach is significantly focused on reducing the environmental footprint and improving the quality of life [
29]. However, due to various challenges, including data protection and privacy, cross-sector collaboration is necessary to ensure the full implementation of technologies [
30]. In this context, energy efficiency emerges as a leading pillar for the long-term success of smart cities. Evans et al. [
31] point out that the optimization of energy resources not only contributes to reducing environmental impact but also directly improves living standards. Suartika and Cuthbert [
32] suggest that technological progress, in itself, is insufficient to achieve sustainable cities without integrating social and environmental factors into planning. Kuru and Ansell [
33] developed the TCitySmartF model, which offers cities a framework for transformation through smart governance, active civic engagement, and technological advancement. This framework allows cities to integrate advanced technologies such as the IoT and artificial intelligence, enhancing key aspects such as energy efficiency and mobility [
34]. Ahada et al. [
35] added that the integration of the IoT with renewable energy sources is crucial for efficient resource utilization, and process automation helps achieve sustainable goals. Smart homes are becoming an integral part of smart cities, contributing to improved living standards for citizens [
36]. These systems increase citizens’ interest in technologies such as smart mobility, encouraging greater engagement in the use of urban solutions. Technologies such as electric vehicles and automated transportation systems not only improve efficiency but also reduce pollution [
21]. When citizens recognize the benefits of smart mobility, such as reduced traffic congestion and improved environmental conditions, their interest in using these technologies increases, contributing to faster integration of smart city solutions into everyday life [
30]. This citizen readiness to engage with and utilize new technologies represents a key prerequisite for the sustainable development of urban environments [
37].
H4. Interest in the development of smart mobility (ISMD) has a positive and significant impact on the level of use of smart city solutions.
Lee, Hunter, and Chung [
38] emphasize the importance of integrating advanced technologies, such as the IoT and big data, in smart tourist cities, which not only enhances the tourist experience but also contributes to the sustainable development of cities. These technologies provide personalized services to tourists and improve resource efficiency while reducing the environmental footprint of cities. On the other hand, Bibri [
39] highlights the importance of an interdisciplinary approach to using big data to address sustainability challenges in smart cities, noting that optimizing technological resources can significantly improve cities’ environmental performance. Lai et al. [
40] view the development of smart cities through the lens of standardization, arguing that technical standards enable faster and more efficient implementation of advanced technologies. They emphasize that standardization is key to achieving energy efficiency and better infrastructure integration. Evans et al. [
31], however, point to practical challenges, such as data security and cross-sector collaboration, which must be overcome to fully realize the potential of smart cities. Silva et al. [
41] study smart city architectures and underscore the importance of properly designing technological solutions in the context of long-term sustainability. Their approach shows that efficient resource management can strengthen cities’ resilience to environmental challenges and enable more flexible infrastructure. In this sense, citizens’ perceptions of the benefits brought by smart cities become crucial for their acceptance and successful integration. Cities that effectively communicate the benefits of smart technologies, such as increased mobility, reduced traffic congestion, and improved quality of life, achieve greater success in implementing smart solutions. Sharifi et al. [
42] suggest that smart cities have great potential to contribute to achieving sustainable development goals but emphasize that citizens must be aware of the advantages these technologies offer. Only through active citizen participation can smart cities achieve sustainability and enhance the efficiency of urban environments.
H5. Perception of the benefits of smart cities (PSCB) positively influences the level of use and integration of smart city solutions.
It is important to emphasize that smart cities are not isolated from their rural surroundings. The development of smart technologies that include both cities and neighboring villages enables a more comprehensive approach to sustainable development at the regional level [
43]. Smart solutions implemented in villages, such as the digitalization of public services, optimization of energy resources, and improvement of communication infrastructure, can significantly enhance the quality of life for rural populations while also relying on connectivity with urban centers [
44]. This balanced approach contributes to the social, economic, and environmental sustainability of the entire region, enabling integrated development that improves living conditions in both cities and villages [
45].
The aim of this research is to examine the acceptance and integration of smart city solutions among the citizens of Novi Sad, with a particular focus on smart mobility and digital services, utilizing the Technology Acceptance Model (TAM). The study addresses the factors that influence citizens’ willingness to adopt smart technologies, such as awareness of smart cities, perception of benefits, and engagement in digital services. Novi Sad, as the European Capital of Culture for 2022, has a unique opportunity to position itself as a leader in the integration of smart solutions, and this research fills the existing gap in the literature regarding technology acceptance in smaller cities, providing valuable insights into citizens’ attitudes. The results will contribute to the development of strategies to enhance ecological efficiency, reduce traffic congestion, and improve service quality, which is crucial for sustainable urban development and quality of life in Novi Sad and the broader region. Previous research has demonstrated the application of the Technology Acceptance Model (TAM) in various contexts. For example, works such as those by Yin et al. [
12] and Davis [
46] utilize this model to explain the acceptance of new technologies. Additionally, the research by Venkatesh et al. [
47] further extends the TAM through the development of the Unified Theory of Acceptance and Use of Technology (UTAUT), emphasizing the importance of social and contextual factors. The application of the Technology Acceptance Model (TAM) is becoming increasingly important in understanding the adoption of innovations in smart cities. Robles-Gómez et al. [
48] explored the acceptance of an IoT cloud platform using a hybrid UTAUT model/TAM, revealing that the perception of ease of use and usefulness significantly influences user behavior. Prakosa and Sumantika [
49] analyzed the acceptance of electronic marketplaces using the TAM, indicating that user trust plays a key role in the success of smart systems. Alsharafat [
50] linked the IS Success Model with the TAM to identify factors influencing the acceptance of mobile learning, emphasizing the importance of system and service quality. In the context of smart cities, the quality of infrastructure can significantly impact citizen engagement. Mailizar, Almanthari, and Maulina [
51] extended the TAM to e-learning, incorporating factors such as facilitating conditions and social influence, further highlighting the importance of community engagement for the acceptance of solutions in smart cities.
The title of the European Capital of Culture (ECoC—European Capital of Culture) held by Novi Sad in 2022 represented not only recognition of the city’s cultural significance but also an opportunity for the city to present itself as a modern center open to innovations and technological solutions that improve citizens’ daily lives. Although the smart city theme was not central to the official ECoC program, the idea of “culture as a way of life” encompasses modernization through smart technologies that can contribute to resource preservation, improvement of urban services, and better quality of life. Digital innovation and smart city solutions enable transformation aligned with the modern needs of the community, supporting ecological, cultural, and economic aspects of sustainability. This research aims to explore citizens’ readiness to adopt innovative solutions within the smart city concept, using the ECoC title as a foundation for the city’s long-term development through the implementation of smart technologies. Although the research primarily focuses on the urban area, there is also a recognized need to integrate smart solutions in surrounding rural communities, where similar solutions can enhance the quality of life. In this way, the development of Novi Sad through smart solutions becomes a natural continuation of the cultural and technological progress initiated during the ECoC year, further strengthening the connection between cultural significance and technological advancement for the entire community.
4. Discussion
Smart cities develop not only through technical innovations but also through active citizen participation, which is a crucial factor for the successful implementation of these solutions. Our findings confirm that awareness of smart cities (ASC) is essential for the acceptance and integration of new technologies, aligning with the work of Yin et al. [
12], who emphasize that citizens must be well-informed and involved in the process for smart cities to become a sustainable reality. In terms of technical solutions, city architecture and sustainability are inseparable elements, as highlighted by Silva et al. [
41]. Our study corroborates that the perception of smart city benefits (PSCB) plays a key role in the acceptance of these solutions, especially in areas like energy efficiency and mobility improvement. Citizens who recognize these benefits are more likely to adopt these technologies, which is vital for the long-term success of smart cities.
Effective data management and integration, as emphasized by Fadhel et al. [
27], are crucial for the functionality of smart cities. Our results indicate that greater engagement in digital services (EUDS) enables better connectivity between technologies, ensuring more efficient implementation of smart solutions. This underscores the importance of integrating various systems, such as transport, energy, and healthcare, which can only be achieved through active citizen participation. Furthermore, the development of intelligent systems in smart homes, as noted by Huda et al. [
36], demonstrates how individual solutions, such as smart homes, can be expanded to the broader urban environment, contributing to city sustainability. Our findings support this idea, showing that younger generations, with a higher interest in smart technologies, are more willing to adopt and use them, further promoting the development of sustainable smart cities.
Nassereddine and Khang [
28] highlight that IoT technologies play a key role in connecting different segments of smart cities, enabling more efficient real-time resource management. Our study shows that interest in smart mobility is a significant factor in the adoption of smart transport solutions, suggesting that citizens recognize the value of the IoT in daily urban services, including transportation and energy management. Moreover, Lnenicka et al. [
61] emphasize the importance of open data as the foundation for better city management. Our results reveal that citizen engagement in digital services is beneficial not only for individual but also for the sustainability and transparency of urban systems. This confirms the need for open access to data in smart cities, which contributes to greater citizen trust and more effective decision-making.
Transportation systems based on machine learning, as Prakash et al. [
21] point out, play a crucial role in reducing traffic congestion and improving transport efficiency. Our study aligns with these findings, showing that citizens who recognize these benefits actively support the implementation of smart solutions in transportation, directly improving the quality of life in urban areas. Energy efficiency, researched by Cui and Cao [
62], is also critical for the success of smart cities. Our results confirm that citizens who recognize the importance of energy efficiency are more inclined to accept smart solutions, which is essential for the long-term sustainable development of smart cities. The connection between perceived benefits and their actual application highlights the need for continuous education and informing citizens about the advantages these technologies bring. Lim et al. [
63] emphasize the positive impact of smart city development on quality of life, but they stress that citizen awareness is key to successful implementation. Our study supports this, showing that awareness of smart cities is one of the most important prerequisites for the integration of technologies and the realization of the full potential of these urban environments.
Our results suggest that the integration of smart solutions into urban areas can directly contribute to better resource utilization and more efficient service delivery, which is particularly relevant for neighboring villages that rely on urban resources and infrastructure. This finding aligns with the research of Komorowski and Stanny [
64], who emphasize that smart villages can emerge near urban centers where they benefit from access to city resources, further enhancing public service efficiency and fostering social and economic connectivity between urban and rural communities. By introducing smart technologies into villages, a synergistic effect can be achieved in which both communities—urban and rural—benefit from improved social, economic, and environmental sustainability [
65]. Meyn [
66] highlights that digitalization can significantly enhance life in rural areas by providing better connectivity and access to resources, thereby strengthening sustainability and economic growth across the entire region, as our findings also confirm. Such a comprehensive approach contributes to cohesive regional development, allowing long-term benefits for both urban and rural communities.
5. Conclusions
This study makes a significant contribution to understanding the factors that influence the successful adoption and implementation of smart city solutions, with a particular focus on the areas of smart mobility and digital services in Novi Sad. Unlike traditional approaches, our findings show that awareness of smart cities, readiness to adopt new technologies, active engagement in digital services, and interest in smart mobility form the foundation for successful integration of these solutions. Compared to similar research, this study emphasizes the importance of technological literacy as a key factor in the urban context, where citizens’ willingness to adopt technologies becomes one of the most critical prerequisites for the success of smart cities.
