Abstract:

As a strategic emerging industry， low-altitude economy is a new track for industrial development and a new engine for economic growth. Urban Air Mobility （UAM） is an important part of low-altitude economy. To gain insights into the key technological research trends and development dynamics within the UAM sector， identify hot topics of research， and unveil the knowledge structure and research scope in Urban Air Mobility. This includes exploring the technological evolution pathways and future application prospects to acquire a profound understanding of the current state of Urban Air Mobility research. A bibliometric analysis was conducted on data retrieved and extracted from the Web of Science Core Collection （WoSCC） database. From the result， UAM research forms a comprehensive framework from technology （e.g.， collision avoidance， high-precision positioning， plus-cruise vertical take-off， dynamic airspace sectorization， etc.） to operations （e.g.， urban air mobility operations， unmanned aerial vehicle logistics route network， hyper-local weather prediction） low-noise landing conditions and consumer intention. The aim is to achieve a safe， efficient， and environmentally friendly urban air traffic system， key technologies that face the unique challenge of addressing the complexity of low altitudes in cities， and the importance of air traffic management and environmental impact should be strengthened during the development of the urban air mobility.
