In recent years, the concept of smart cities has gained significant attention to create more efficient and sustainable urban environments. At its core, a smart city is a city that leverages advanced technology and data-driven solutions to improve the quality of life for its citizens. Urban planning is a critical aspect of a smart city, as it involves the design and development of urban areas that promote social equity, economic growth, environmental sustainability, and community well-being. By integrating smart city technologies and urban planning, cities can become more efficient, resilient, and innovative, leading to a better quality of life for citizens and a more sustainable future for our planet.

Digital Twins are virtual replicas of physical objects or systems that are created using real-time data, simulations, and other digital technologies. In the context of smart cities, digital twins are being used to create virtual representations of entire cities, allowing for the testing of various scenarios and the development of more effective policies and strategies.

The Metaverse is a concept that refers to a virtual world or environment that is created through the use of augmented reality, virtual reality, and other digital technologies. It is envisioned as a shared space where people can interact with each other and with digital objects and systems in a variety of ways.

The questionnaire for urban planning is designed to gather socio-techno-economic requirements from various stakeholders, including local authorities, urban planners, and policymakers. The primary objective is to develop a digital platform with 4D functionalities that can integrate smart city data using Digital Twin and Metaverse technologies. The questionnaire aims to identify gaps and opportunities in urban planning and development, and to guide the development of a Digital Twin solution that can be used to assist efforts for sustainable urban planning. Additionally, it aims to collect data on specific issues or challenges related to urban planning, such as transportation, housing, public spaces, and environmental sustainability.
