Urban low-altitude logistics network schematic with multiple altitude layers (IMAGE)
Caption
The urban low-altitude logistics network adopts a hub-and-spoke, multi-layered structure. Its nodes are waypoints mapped to corresponding altitude layers based on spoke nodes (delivery spots) and hub nodes (distribution centers), while the links represent horizontal connections between these waypoints, categorized into three types: hub-hub, hub-spoke, and spoke-spoke. Network planning must take into account factors such as ground safety risks and noise-sensitive facilities. Ground risks are classified into low-risk and high-risk areas based on population distribution, and noise-sensitive facilities refer to residential areas.
