Cover Story: E-commerce growth strains traditional urban logistics, prompting drone networks for last-mile delivery. Current planning methods face route conflicts and inefficiency. This study proposes a stratified airspace solution: upper-layer transshipment routes connect essential nodes for fast cargo transfers, while lower-layer delivery routes facilitate door-to-door services. A double-layer model is designed to optimize transshipment node placement and route planning. A case study validated the model, deploying 17 transshipment nodes with 26 transshipment routes and 56 delivery routes, showing smaller network size, higher operational efficiency, and fewer intersections versus single-layer networks, confirming double-layer networks' superiority in safety and scalability for urban logistics.
