1 Motivation
City is a complex system comprised of multiple interconnected systems, and, from an information and communication technology (ICT) perspective, smart sustainable cities require the integration of various systems, devices and services to address urban challenges.
A smart city platform enables this integration amongst various systems to offer the urban operation and services supporting the functioning of city services, as well as efficiency, performance, security and scalability.
For instance, enhancing efficiency can be achieved by connecting and coordinating individual systems within cities and communities such as water, electricity, waste management and transportation and facilitating the exchange of data from different domains within cities.
Smart city platform, including digital twins for cities is recognized as a promising approach to enhance urban planning and to develop successful smart sustainable cities. In the context of digital twins, the physical reality of an urban space is replicated in a digital environment, enabling real-time interaction between the physical and virtual models. This includes activities such as real-time monitoring, analysis of various phenomena, prediction of the future through simulation, and visualization of various characteristics.
There will be many digital twins within a city. These may address different city challenges such as transport, energy, or disasters, or different parts of the city such as main railway stations, airports, or new city districts. By federating the different digital twins, challenges spanning multiple domains and areas can be addressed.
In addition to apply digital twins, cities are now trying to implement metaverse amongst other technologies to move toward to citiverse. The citiverse implies a digital representation of a city or urban environment, integrating smart sustainable city technologies, the Internet of Things (IoT), and digital twins. It aims to create virtual replicas of cities to enhance urban planning, sustainability, and citizen engagement.
This Question addresses use cases, requirements, architectures and data sets and format to support interworking and between smart city platforms including digital twins in cities and communities.
