Exploring the Collaborative Development Model of Urban Low-altitude Airspace and Surface-Subsurface Spaces Oriented by UAV-based Traffic Governance
Abstract：
This paper explores the evolution of Chinese urban spatial planning from 2D to 3D, the transformative impact of new transportation modes on urban development, and the supportive role of information technology. It proposes a novel approach to urban development that integrates low-altitude airspace and above-ground space. The author conducts a historical investigation and literature review of the development process of domestic and foreign urban low-altitude airspace control, and sorts out relevant regulations and policies, and then puts forward the concept of overall development and design of urban three-dimensional space. Firstly, by establishing a functional group consisting of “airport-satellite city - central city”， three levels of airspace（ low altitude - low medium altitude - low high altitude） are constructed. Secondly, within the central urban area, a three-tiered pipeline airspace flight traffic system is developed based on these levels of airspace; specific flight corridors are designated for manned aircraft as well as large and small cargo UAVs using ecological green corridors, closed roads within cities, rail transit systems, and areas with concentrated high-rise buildings, respectively, to ensure a safe operating environment. Lastly, by leveraging urban civil aviation airports, three-dimensional transportation systems, and central business complexes, a collaborative layout can be achieved through the comprehensive use of high-rise buildings, parking structures, light rail and subway stations to create a “low-altitude airspace - above-ground underground” integrated urban transportation system, expand the “TOD+ UAV” model and enhance overall city operation efficiency. Seizing the new opportunity of urban air traffic reform will promote interaction and cooperation between urban groups and neighboring cities while injecting new vitality into the urban economy.
