### Smart City Conceptual Model  
The concept of smart cities has become important in the last decade because it allows the improvement of the quality of life of citizens, makes intensive use of information technologies, facilitates intelligent decision-making in real time, increases competitiveness, economic growth and complies with the principles of sustainable development. In recent decades, population growth has progressively increased, and cities have become key in socio-economic development by concentrating population and economic activity in urban centers. According to the estimated United Nations report, approximately 70% of the world's population will live in cities by 2050 [5].  
A smart city integrates information and communication technology with physical, digital and human systems to ensure a sustainable and prosperous future for citizens. It can improve the quality of life of its inhabitants in many areas, such as smart home, smart healthcare, transportation and the smart community [6].  
The smart city's objectives are to improve the efficiency of the cities of the future and the quality of life of their inhabitants, to promote the socio-economic development of cities, not only by making use of new technological applications but also by making existing processes smarter [7].  
With the application of information and communication technologies (ICTs), smart cities are more efficient in their use of physical infrastructure and resources and learn and adapt efficiently to any type of change and participate with citizens in local government [8].  
The realm of smart cities is probably where the Internet of things (IoT) has been most forcefully applied so far because what surrounds us has to be connected and, at the same time, interconnected with each other.  
IoT describes a world where everyday objects are always connected to the Internet, allowing them to communicate and interact with each other. By connecting these everyday objects to the Internet and making them available anywhere at any time, IoT allows you to remotely monitor, manage, and collect status information about them and their environment [9].  
A smart city is one that undertakes initiatives in at least one or more of the following six features: smart mobility, smart governance, smart economy, smart people, smart Living and Smart Environment. This classification is well known and used by many researchers [10].  
Additionally, according [11] present a holistic approach for the conceptualization of a smart city, where is key to consider the components, technological, management, and policy components. In some cases, the cities are considered as smart. However, the important thing is to distinguish between the degree and the nature of intelligence, rather than a dichotomy between \"being intelligent\" or \"not being intelligent\". Intelligence should be seen as a continuum in which local government officials, citizens, and other stakeholders could think and implement initiatives that try to make a city smarter: \"a better place to live and work. [12] presents a brief description of smart cities, followed by the features, generic architecture, composition and real-world implementations of smart cities among the various concepts that use ICT in urban environments, for example, digital city, green city, sustainable city, smart city, etc.  
In the work of [13], discussed information technology as a fundamental and transversal element in the development of smart cities, to generate added value to the sectors of a smart city and its economy, environment, education, mobility, etc. Colombian cities do not have valuation models on technology management capabilities, so the proposed model is an instrument for the implementation of smart city initiatives.
