Smart Cities Landscape and Urban Planning for Sustainability in Brno City

: This study aimed to explore the case study of Brno city regarding smart city models. We analyzed Brno considering smart and sustainable city elements, i.e., smart mobility/public transport, smart technology, smart people, smart governance, smart economy, smart living, and smart environment based on transport, energy, and environment referred herein as the smart city and sustainability model. Therefore, we investigated a case study of Brno city in the Czech Republic. We used qualitative techniques such as case study, exploration, observation, and description. We analyzed and comprehended the trends in the various features of smart city and sustainable development of the city of Brno. The ﬁndings showed that Brno city is doing its best to maintain smart city models through its governance organs and structures. The city is also working hard to improve some of the aspects that are still lagging. The ongoing developments and the future ones are based on strategic planning for both the short term and long term such as Brno2023, Brno2030, and Brno2050. It was found that Brno has a very well-planned transport system and is integrated with other aspects such as technology, energy, such as the electricity that moves the trolleybuses and trams, and environment. We strongly conclude that even though Brno city still struggles to achieve total sustainability, it is still a model and reﬂection of a smart and sustainable city. Finally, we noted that Brno city has very good plans and vision the “DNA” of a smart city. However, the implementation still suffers political willingness.


Introduction
In Europe and the United States of America (USA), at the turn of the 20th and 21st centuries, there was a clear change in the theory and practice of city planning. Since computerization was becoming more common in the 1980s and 1990s, it began to be a key influence in this area [1][2][3]. The idea of Smart city (S.C.) can be described as a turning point in the history of urban planning, precisely, the same way as in the past decades, e.g., the significant reconstruction of European cities in the post-war period, which dominated the second half of the 20th century in the continent. The implementation of this new urban paradigm-although not without difficulties-means that information technologies are used to an increasing extent to solve problems limiting the sustainable development of modern cities [4][5][6][7].
In common understanding, a Smart City (S.C.) is one in which Information and Communication Technology (ICT) is of crucial importance for managing all its most essential functions. The scale of the increase in the phenomenon is illustrated by the data from the This study, therefore, investigated a case study of Brno city in the Czech Republic in the light of the smart city and sustainable development. The main question was, does Brno city meet the standards of smart city status? We hypothesized that Brno city covers aspects of smart city.

ICT and Other Technologies, and Data and Information
The level of communication and technologies used in smart cities differentiates them from others. For instance, smart cities build virtual, wireless, and ubiquitous systems to connect and ease lifestyles' mobility. Technological development in smart cities involves interconnections between networks, virtual systems, and other architectures [17].
Smart cities are considered an upgrade due to the capacity to share and process information through ICT sources. The future of interconnections requires real-world data and real-time integration of stimulating developments to improve decision-making processes [17]. Hence, smart cities advance because they build information-based infrastructures to provide viable solutions.

The Role of Governance in Achieving Smart Cities
The conceptualization of smart cities is a process that accounts for governance, and decision making is a collective approach to ensure the promotion of city management by the government. Several researchers highlighted that implementing policies is a governance role that promotes structures to ensure that smart cities exist [18]. Other studies indicate that smart cities exist; urban governments must endorse higher education centers to achieve them [19]. Profoundly, this idea resonates with Gil, Carvalho, and Paiva, who claimed that the governance of the smart city must focus on initiatives aimed at achieving the fate [20]. In this concept, it is relevant that policy making is a significant priority for city governments. Dijon's city's impact on governance was illustrated when it introduced street lighting management, quality of WI-FI services, and smart traffic management by centralizing the solutions [13]. Hence, it is through governance that smart cities get to adopt policies tailored to meet global standards. Similar examples of cities are represented by Bristol or Warsaw [27,28].
Cities are a convergence of multiple cultures and territories, ideal for local authority contradictions due to distinct interactions and conflicts about decisions. When authorities disagree on sustainable development (social, environmental, and economic), cities cannot be efficiently managed [21]. However, with studies on Information and Communications Technology (ICT) and governance, interactions between local authorities have changed the trend to focus on solutions that merge government roles to foster growth. Bamwesigye and Hlavackova argued that combining ICT tools with the government helps in decision making, focusing on uniting people's ideas to achieve sustainability [22]. Furthermore, considering that smart cities target sustainability, cultural differences can change cities' outlook [18]. This sentiment requires administrative structures and government agencies to involve stakeholders in transforming the interactive system to ensure inclusion [20]. Therefore, smart cities' governance is related to leadership models that promote merging cultures to achieve interaction and collaboration.
According to the research, governments have taken an innovative approach to reduce costs, connect environments, and engage different problem-solving stakeholders [23]. Successful cities' innovations require governments to integrate ICT in strategic administration to reform government institutions [21]. Moreover, the digitalization government can transform organizations by improving public sectors' efficiency to provide services and deliver societal solutions [24]. This concept's operationalization relies on transparency and openness in building citizen-centric services to engage in sustainable activities [29]. In this sense, the government assumes oversight to increase communication ability and reduce human error in institutions. Therefore, governance is a crucial step towards implementing innovative approaches that focus on reducing operational pressures.

Government Intervention to Achieve Smart Cities
In cities aspiring to attain smart status, increasing citizens' needs for democratic practices have emerged through government involvement. Governments have the investment capacity to advance ICT as a channel that focuses on improving communication and interactions with citizens [30]. Given that smart cities rely on attracting people to engage in innovations and advance sustainable growth-seeking, both the private and public sectors use interventions that foster development [31]. Social inclusion has become a priority in Spain after recording high numbers of older people dying in solitude, yet policies can be implemented to track people [32]. In developing smart cities, it is interesting that governments engage citizens on all fronts because social issues are different across regions [29]. Therefore, the degree of government involving citizens impacts the process of achieving governance in smart cities.
Improving public service efficiency in delivering essential activities has become a core purpose for smart cities. By financing smart cities' technological needs for development, the government must improve public service to reduce transaction costs when contracted efficiently [23]. This can enable efficient information, health, education, and transportation management to improve production and infer knowledge to generate essential services [33].
Other studies indicate that urban infrastructures are developed to provide essential services vital to health and sustainability [34]. In this regard, smart cities rely on governance that adopts practices to increase residents' welfare and sustainable development aims [35,36].
While discussions about governments' involvement in smart cities have been broadly covered, outlining development needs must emphasize problem-solving. Voordijk and Dorrestijnss claim that citizens should participate in local administration structuring through democracy [24]. Smart cities' results show that governments moving towards an allinclusive governance approach are on a higher development trajectory than their counterparts [20]. Other researchers found that introducing smart technology has influenced urban neighborhoods' sustainability as cities seek low densities and operational costs [22]. The arrangements being taken by governments to address problems show that integrating solutions with the public is essential for smart cities because they must serve citizens.
Government interventions to achieve smart city status have focused on including disadvantaged and vulnerable populations [37]. In both developed and developing countries, smart cities aim to promote the inclusion of disadvantaged people. According to Mutiara, Yuniarti and Pratama, smart cities' development targets go beyond the quality of life and uplifting of underprivileged persons because enhancing their capabilities can contribute to equality diversity [38]. By addressing issues hindering social justice, governments can adopt reforms to ensure the participation of various groups in meeting the development needs of smart cities [35]. When developing information technology, underprivileged populations must be accounted for to benefit from the developments. Smart cities should be the governments' way of achieving sustainable development goals by integrating societies' fundamental needs.

Primary Tools in the Governance of Smart Cities
Technology is a leading tool in smart cities' governance, and the physical foundations of all initiatives are developed around it. In cities such as London, Meijer and Bolívar established that the concept of "datafication", which was made possible with IoT (Internet of Things), to build infrastructures with the potential of advancing sustainability [39]. Other studies paint that governments use technology to easily equip everyday objects with digital communication controllers to communicate and interconnect regions through smart devices [40]. In Brazil, blockchain technology has led to transparency in medical records, privacy, and lowering costs by designing smart contracts [41]. Therefore, ensuring the proper use of technology is crucial to governing smart cities because it fosters connectivity.
The impact of human capital is indispensable in developing and governing smart cities. As several researchers suggest, governments must ensure that citizens attain sufficient technical and education skills to help them navigate the smart city environment [42]. Another study provided an example of the Romanian government, which created "knowledge cities" by launching e-government portals to engage stakeholders in the private and public sectors' vital services [43]. Human capital benefits in the governance of smart cities; initiatives must be taken to ensure efficient operations by enhancing adaptation to handling privacy and security issues within the city environment [44]. However, many cities aiming for a smart status still lack the technical capacity to integrate applications with people [45]. Hence, by training human capital, smart cities can develop more by sourcing the best management through technical capacity-building.
The active participation and engagement of citizens in the development of smart cities can lead to enhanced governance. Various scholars identified active engagement as a crucial facet of empowering citizens, fostering digital inclusion, collaboration, and changing perceptions among communities [33]. Paris commissioned vegetation as a bio-air conditioning source in France by turning rainwater into clean energy involving farmers [46]. Further, the same study established that the ranking of smart European cities such as Lisbon, Berlin, London, Helsinki, and Copenhagen shows that they pay attention to smart sustainability, improved bicycle networks, wastewater treatment, and unemployment [46]. This development level is attributed to citizen participation in symposiums exploring flexible ways of creating partnerships to address private and public sector concerns that limit improvements.
Other researchers suggested that urban planning is a purpose-driven approach using data to analyze populations' needs in smart cities [22,47]. For instance, the Smart London Plan was developed based on data technologies to improve citizens' welfare by identifying areas that require refining. Bamwesigye and Hlavackova suggest that smart cities adopt plans to promote approaches by utilizing information consistent with opportune areas where developers use necessary changes tailored to meet people's social needs without compromising the future needs [22]. This entails finding future physical objects that will impact lives and develop and merge them with current urbanism elements for sustainable development.
A case study of Brno was selected and explored concerning smart city options and models. We based our study on a smart city and sustainability model (SCSM) of environment, technology, and people's quality and livelihood. Strategic documents of Brno city were also analyzed to see if they conform to sustainability aspects of smart cities.
This study explores the city of Brno. We studied the history of this city in terms of socioeconomic and structural changes over the decades.
To fulfill the study's aim, an extensive study of the related literature on smart city options and sustainability. Major keywords included are smart city, urban green infrastructure/green spaces, bult areas, smart transport, smart environment, smart city governance, and sustainability. Some important databases such as Scopus, Web of Science and google scholar were searched for related study materials. Based on all the materials, we give an expert view of Brno city given smart city and sustainable development.
At the heart of Europe, Brno city connects major cities such as Vienna, Prague, and Bratislava. It is an important city in both local and international development, economically and structurally ( Figure 1).

At the heart of Europe, Brno city connects major cities such as Vienna, Prague, and Bratislava. It is an important city in both local and international development, economically and structurally ( Figure 1). The city of Brno has approximately 400,000 inhabitants and about another 150,000 people travel to the city daily for work, education and or other services. There, the future of such a city needs a constant debate on best options of sustainability. The city of Brno is often perceived only as a political symbol or offices; similarly, it forms city districts, city companies or establishments. Brno participated in preparing the strategy with partners from universities, research centers, companies, non-profit organizations, and active individuals [44,[51][52][53].
The Strategy Brno2050 is the basic strategic development document of the city of Brno. The subsequent strategy is the strategy of the city of Brno and its inhabitants. The main advantage is the setting of key goals and priorities for the city's sustainable development. The strategy creates an agenda for the direction of some sectoral policies and the basis for active action decision making in the medium and long term of the city development journey ( Figure 2) [44,51,52].

The steam traffic did not disappear even after the electrification of passenger traffic. The number of steam locomotives was only reduced to four, which were used in freight siding and could only be included in passenger transport in the event of power outages or to cope with increased traffic on Sundays and holidays [53,54,56].
The last steam locomotive "Caroline" (now an exhibit of the Technical Museum in Brno) delivered railway trucks through the city streets of Brno until February 1926. This ended the first stage of steam traffic on the Brno street traffic tracks. The second stage of steam operation occurred in the 1940s after connecting the local railway Brno-Líšeň to the Society of Brno Electric Street Railways [53,54,56].
In 1900, the Austrian company "Österreichische Union Elektrizitäts Gesellschaft" began in Brno with an electrically powered street railway. In 1900, a joint-stock company with the city of Brno "Gesellschaft der Brünner elektrischen Strassenbahnen" (Brno Electric Street Railways Company) was established. This company is the direct predecessor of today's transport company. Its operation started on 21 June 1900, on modified steam lines [53,54,56].
After constructing other lines, at the end of 1903, five lines were in operation, distinguished by colored targets. The fleet consisted of 41 motor and 12 towing cars manufactured in Graz and 29 modified towing cars from horse and steam railway. The first domestic cars were seven motor cars from the Brno company Lederer-Porges (later Královopolská strojírna) delivered from 1903 to 1904. The old depot in Pisárky was rebuilt for electric operation, and a new one was built in Králové Pole (now it serves as a substation building). Before the First World War, the street railway network underwent only partial modifications and changed [53,54,56].
The 1920s and 1930s were marked by the rapid development of the railway and the related changes. The expansion of tram lines and facilities for buses were built in Husovice and two new substations with fully automated operation, i.e., Tábor (1926) and Křížová (1928) [53,54,56].
Between 1930 and 1945, Brno Street Railways Company introduced bus transport to supplement the existing tram transport. By the end of 1938, 11 bus lines were in operation. The Second World War had a very negative effect on the entire urban transport system. After the bombing of Brno, a significant part of vehicles and equipment was destroyed. The renewal of tram traffic took numerous months. In addition to repairs to damaged tram lines, it was also necessary to ensure the revival of the overhead line, which was up to 60% devastated. The electric operation was not fully resumed until 1945 on ten lines with a total length of 74.6 km. After the war, bus transport had to be rebuilt from scratch, as most of the operational buses were confiscated by the retreating Nazi army [53,54,56].
In 1951 to 1970, The original joint-stock company operating public transport had been replaced at the end of the 1940s by a municipal company, which from 1951 was given the current name Dopravní podnik města Brna (DPMB) [39,53]. By the 1960s, there was no significant expansion of rail transport, which was completed in the post-war years. A significant modernization of the tram fleet began with introducing four-axle T-series trams fromČKD Prague, derived under the license of American PCC cars. In 1967, the fleet was supplemented by K articulated vehicles [53,54,56].
In 1968, the company operated 17 permanent lines with a total length of 158 km. The operation of more powerful traction vehicles has significantly increased the demands on the traction power supply system. In 1970, 10 stable substations with a total output of 30 MW were in operation. Bus transport has become a seemingly simple solution for transport services in new housing estates. However, the fuel crisis in the 1970s again turned its attention to electric traction. The city of Brno, as one of the few cities in the Czech Republic that did not succumb to the tendency to disrupt the lines, could proceed to the renaissance of trolleybus traffic. Several new tram lines were built along separate bodies to Land 2021, 10, 870 9 of 17 serve new satellite housing estates. However, these high-capacity sections were connected to the existing rail system in the city center [53,54,56].
In the 1980s and 1990s, the operational stagnation of the system began to show. The rapid growth of individual motoring had exposed public transport to a sharp confrontation. Therefore, the city management adopted a decision on the organizational change of the public transport system as a measure with temporary effect until the final solution to the rail system's capacity. The new system was implemented in 1995. The change in the organization of public transport operation was caused by the need to streamline its operation. Emphasis was placed on the preparation and implementation and maximum use of tram and trolleybus traction and reduction in parallel bus lines ( Table 1). The ecological situation of the city center and other vital localities were considered to modify the tram network [53,54,56]. Table 1. Number of transport lines in Brno city based on DPMB data -prepared by authors [53,55,56].

Transport Lines Number
Tram lines (of which depart from the city of Brno) 11 Trolleybus lines (of which depart from the city of Brno) 13 City bus lines daily (of which depart outside the city of Brno) 43 City night bus lines (of which depart outside Brno) 11 Regional bus lines running on the territory of the city of Brno 29

Governance of Brno City
Brno city has been found to be one of the cities outstanding smart city governance in the Czech Republic and Europe, and the globe. Brno city governance is considered to have the willingness to improve the livelihood of the city dwellers and the environmental aspects of the city's development. Amongst Czech cities, Brno city showed strategic planning, strength and willingness [58,59]. The city with a long history of planning for building and transport development dates back to the 18th century. It has numerous plans for the city ranging from waste management, energy, transport, environment, water, education, health care, and safety [51- 54,58].
Brno has now projected their long-term vision, i.e., Vision2050 [51]. It also has shortterm development goals that subscribe to Vision2050 [51,52]. Even though Brno city has some of the best planning documents for achieving smart city sustainability, Brno struggled with decision making regarding implementing the planning documentations and vision [57]. This is where the role of governance comes in. Governance and management provide the day-to-day administration and implementation of the plans and vision of the cities. However, this faces many challenges from the political changes in the towns as each political party comes with its agenda and objectives [51]. Brno city scored highly in aspects of administration and experts regarding implementation of the city plans, but it was suggested that it still suffers the political changes whose terms change with time [44,51].

Transport in Brno City
Brno was found to have an integrated and intelligent transport system [22,[53][54][55][56]. We noted that Brno had come a long way in systematically planning and improving its transport system (Table 1, and Figures 3 and 4). On the ground, we observed that the transport system in Brno is not just the trams and bus lines and the infrastructures, but also the connection with technology, connections with energy, water and waste management of the city. To achieve smart city sustainability, cities have to take a multidimensional approach to implement the aspects of development aiming to achieve a good quality of life for the people in the city [22,59]. This is the conceptualization of this study, which we referred to as an integrated approach. transport system (Table 1, and Figures 3 and 4).

To achieve smart city sustainability, cities have to take a multidimensional approach to implement the aspects of development aiming to achieve a good quality of life for the people in the city [22,59]. This is the conceptualization of this study, which we referred to as an integrated approach.     The Brno transport system is interconnected with numerous connections. These connect buses to trams and vice versa. This is supplemented by the regional trains and buses, which bring people outside the city of Brno city, hence connecting to their destination in and around the city (Figures 3 and 4) [22,[53][54][55][56][57]. The Brno transport system is complementary to the economic development of the city. The movement of people and goods in the city is seen to be very well connected as well. The city transport alone made profits accounting for the year 2019 was reported at the amount of CZK 98,437,625.71 [53][54][55][56]58,59]. The company's (DPMB-Dopravní podnik města Brna, a.s.) [55,56] own management in 2019 had a positive performance both in the public service obligation and in business/commercial activities. In 2019, DPMB reached its largest year-on-year increase in the cost of repairs, especially infrastructure, at CZK 358,292,930 [55,56].
The total revenues in 2019 were CZK 3,324,316,437.81 with a year-on-year increase in CZK 89,359,107.22. Only revenues from profitable commercial transport improved by CZK 90,552,953.36 continuously from previous years. This development had a key impact on the economic result and activities in the transport sector [55,56].
Lately, DPMB, the Brno city transport company, has heavily invested in transport and technology investments. This involves the other interconnections of water, waste management as well as energy. The company invested in new trams, buses, and the internet, among other technologies such as a central public transport control center for the whole city (Figures 3-6). The Brno city transport company has also improved payment conditions from cash to pay by cards facilitated by the internet. The station ticket machines are still in operation for those who want to buy by cash on most tram or bus stations.
All public transport offers free internet and apps such as "IDOS" where passengers can quickly search for their connections and stops. This makes the livelihood for city dwellers in Brno not only easy but also efficient.
Based on the Smart City and Sustainability Model (SCS Model), the Brno city transport system is connected to other components of smart city such as energy, ICT, and environment ( Figures 5 and 6). Nonetheless, a few things such as strictly only bus and trolley bus lines could reduce traffic during rush hours. Moreover, they would motivate more working class to use public transport if no delays. This has been implemented in some cities in the world, especially in the Netherlands [22]. Cycling structures in the old infrastructure had not been catered for, scaring away many potential daily cycling to work and leisure. As mentioned, new structures seem to care for cycling and pedestrians but still on a small scale.

Integration between Transport, Building, and Green Spaces in the City
The management and administration of the city of Brno have demonstrated a balance between the built areas, green spaces and playfields, and buildings. This is shown in the plans and can also be seen physically on the earth maps and by observation. We observed that according to the prerequisites of smart and sustainable cities, Brno has done very well even if it still has a lot to do to keep the balance [22,41,42,[58][59][60][61].
We observed that much of the green zones are in the peripheries of Brno. However, there are many green zones in Brno. Some of these are playfields while others are arboretum gardens with various vegetations (Figures 5 and 7) [41][42][43][57][58][59][60][61]. These serve as leisure spaces for the city dwellers and tourists since some of them are conserved by international declarations.
The greenery systems and urban nature ecosystems help reduce urban pollution by reducing the carbon dioxide (CO2) in the atmosphere. In the same process, greeneries also provide clean air for the urban population and animals [22,51,52]. Therefore, the ecological and environmental development roles of integrating greenery systems in the transport, and built areas is of paramount functions [22,26,58,59,[62][63][64][65][66][67][68][69][70][71][72][73]. We can ably argue that the urban dwellers also enjoy psychological benefits from interacting with urban nature [74][75][76]. By merely looking at nature, it is very relaxing for the brain and body for some people.

Smart cities are gradually becoming our reality. It can be seen, for example, based on scientific publications on this subject, the number of which increased 120 times in 20 years from 138 in 1996 to 16,500 in 2015 [7]. However, in the opinion of some scientists [4], the effects of implementing the smart city policy are not sufficiently taken into account in scientific research. Nevertheless, an analysis of the literature on the subject by Bhosale et al. [7] indicates that the scope of research on S.C. goes beyond the technological aspect itself, especially concerning Europe. The subject matter of these scientific works considers a more holistic interpretation of smart cities, emphasizing that their development depends on the balance between human, economic, social, cultural, environmental, and technological factors [22,44,[61][62][63][64][78][79][80][81][82][83].

Since the term "smart cities" is, in a sense, still a new term, its meaning can be misleading. The colloquial meaning of S.C. is understood as using the data (continuously increasing) gathered thanks to ICT to guide the decision-making process in the city. However, a more critical look at the "smart city" may suggest a clever marketing concept designed to promote the industry of the largest ICT companies with a vested interest in selling their products and processing citizens' data for commercial purposes. In this context, there are concerns, such as privacy breaches resulting from the introduction of hidden electronic surveillance systems increasingly used in the public space [4,22,77].
Regarding the issue of smart cities lately, Hambleton [4,10] notes that cities around the world are now facing four main challenges simultaneously: • The COVID-19 health crisis; • A sharp economic slowdown due to the pandemic; • Growing climate problems; • An unacceptable increase in social, economic and racial inequalities.
Of course, concerning the above problems, advances in ICT can significantly improve the quality of city management. However, as Hambleton [4,10] states simply obtaining gigantic amounts of data about society (zeta-and yotabytes) will not improve the quality Since the term "smart cities" is, in a sense, still a new term, its meaning can be misleading.

The COVID-19 health crisis; • A sharp economic slowdown due to the pandemic; • Growing climate problems; • An unacceptable increase in social, economic and racial inequalities.
Of course, concerning the above problems, advances in ICT can significantly improve the quality of city management. However, as Hambleton [4,10] states simply obtaining gigantic amounts of data about society (zeta-and yotabytes) will not improve the quality of life in cities. To successfully meet the above challenges, traditional thinking about smart cities should instead be replaced by implementing so-called "wise cities". More so, ICT is an engine of development through use of big data, communication, city operational governance systems and city services becoming highly responsive and quality life [84][85][86]. Moreover, it is argued that the goal of smart cities is to achieve good quality of life of the people and sustainability of their neighborhoods. This is the ultimate goal of urban utilities in long run [22,44,[78][79][80][81][82][83][84][85][86].
The literature section dealt with the expounding on smart cities and an in-depth analysis of each element of the smart city. Moreover, the section also studied and explained the means of achieving smart and sustainable cities, such as public service administration and management. We went on to discuss the role played by governance in achieving smart cities. This is because there must be a team of experts implementing this.
We used qualitative techniques such as case study, exploration, and description. We were able to analyze and comprehend the trends in the diverse features of the smart city and sustainable development of the city of Brno.
The findings showed that Brno city is doing its best to maintain smart city models already built through its governance organs and structures. The city is also working hard to improve some of the aspects that are still lagging. For example, new streets have bigger walking pavements with riding lanes. The ongoing developments and the future ones are based on strategic planning, which considers both the short term and long term such as Brno2023, Brno2030, and Brno2050, as well as the needs of the people.
It was found that Brno has a very well-planned transport system and is linked with other aspects such as technology (internet and other technologies such as payment systems), energy, such as the electricity that moves the trolleybuses and trams, solar innovations, and environment. The system of Brno city is very interconnected in terms of transport, energy, and environment, referred to in this study as the smart city and sustainability model. These three aspects are also linked with the building systems and built areas. We strongly conclude that even though Brno city still struggles to achieve total sustainability, it is still a model and reflection of a smart and sustainable city. From infrastructure development, technology, and the green spaces and nature in and around the city, one would appreciate the efforts to balance infrastructure development, technology, and nature to benefit the people and environment [61-64, [78][79][80][81][82][83]. Such an integrated approach and conceptualization could inform policy making and practice that can achieve smart city and sustainability [78][79][80][81].
We observed a few deficits, which are not limited to: There are limited cycling lanes in the city. However, much the city and development partners have bought and distributed cycles and scooters in and around the city, the number of safe demarcated lines is still limited. This could be linked to structural designs, which previously did not cater for such.
Other small aspects have not been carefully catered to the challenges of space in the city and the increasing city population. Given the space between parked cars and the buildings, it is very hard for pedestrians and disabled people in wheelchairs to use in some streets.
