# Metaverse Meets Smart Cities--Applications, Benefits, and Challenges
## 3 Related Work  
A comprehensive qualitative literature and internet search was conducted to identify related works to this study. The literature databases Google Scholar, Scopus, and Web of Science were searched, each with the search terms \"Smart City Metaverse\", \"Urban Metaverse\", \"Municipality Metaverse\", \"Metaverse City Applications\", and \"Metaverse Risks Challenges\". We found that five search results particularly addressed the applications and challenges in the context of the metaverse in combination with the smart city. These studies were then selected for a more detailed review and comparison.  
In their study, [PERSON] et al. examine how digital platforms are shaping urban life, focusing on the emergence of the metaverse as a virtual city concept. They explore the potential impact on urban planning, services, and social dynamics, highlighting both opportunities and concerns for policymakers and researchers [4].  
[PERSON] et al. highlight the growing global trend towards the metaverse and its potential to revolutionize smart cities through immersive digital spaces. They discuss the benefits, technologies, and research challenges associated with utilizing the metaverse for innovative smart city applications and outline future research directions for its integration [24].  
An article by [PERSON] et al. discusses the connection between the concept of the smart city and the rise of the metaverse. The authors emphasize the opportunities that the metaverse offers for promoting smart cities. They introduce the future vision and applications of smart cities based on the metaverse. In addition, they explain the technologies for smart cities in the metaverse and existing solutions. Despite the potential of the metaverse, some concerns and unresolved problems are also discussed [19].  
[PERSON] and [PERSON] address various influencing factors, such as the listing of Rolbox on NASDAQ and the introduction of the \"metaverse city\" Seoul, thereby shedding light on the metaverse in different contexts. The article compares various research trends in connection with the metaverse to possible integration into smart cities [25].  
An article by [PERSON] deals with the connection between virtual worlds and the metaverse from the urban quality-of-life perspective. Specifically, the paper analyzes ways the metaverse can be integrated into the smart city ecosystem to improve quality of life [22].  
Although these studies deal with relevant aspects, they only cover partial areas and do not provide a comprehensive presentation of the areas of application and challenges of the metaverse in the context of the smart city. Furthermore, the challenges are not explicitly assessed in connection with the possibilities of the smart city but are considered in a purely abstract manner. This means that there is still a research gap concerning a comprehensive and practice-oriented consideration of the potential of the metaverse for the smart city. It is considered timely and valuable to fill this gap by collecting a comprehensive overview of smart city metaverse applications and challenges.
