Using Uncrewed Aerial Vehicles (UAVs) to monitor the condition of nodal transportation assets—airports, seaports, heliports, vertiports, and cargo terminals—presents a transformative approach to traditional inspection methods. The focus on nodal assets rather than linear assets like roads, railways, bridges, and waterways fills a gap in addressing the dynamic challenges specific to transportation hubs. This study reviews scholarly literature on applying UAV-based remote sensing (URS) techniques to assess the condition of various transportation hubs, which are critical junctures in global logistics networks. Utilizing a systematic literature review framework, this study reviewed 486 publications from 2015 to 2023 to extract insights from the evolving discourse on URS applications. The findings suggest that these emerging methods resulted in substantial enhancements in time saving, cost efficiency, safety, and reliability. Specifically, this study presents evidence on how URS approaches can overcome the constraints of conventional inspection methods by enabling rapid, high-precision mapping and surveillance in complex and constrained environments. The findings highlight the role of UAVs in enhancing operational workflows and decision making in transportation planning and maintenance. By bridging the gap between traditional practices and innovative technology, this research offers significant implications for stakeholders in the field, advocating for a shift towards more dynamic, cost-effective, and precise asset management strategies.

“…It incorporated the design of the number of circle layers, the circle radius of each layer, and the number of hover points [12]. Shao concluded that the frustum of a cone airspace was more suitable for the operation of eVTOL and its radiation structure could effectively increase airspace capacity, operation efficiency, and the utilization rate of airspace resources [13]. The above research focuses on single landing pad, even multiple landing pads are considered as single landing pad, and the simultaneous operation of multiple landing pads is not considered.…”

Vertiports in economically developed areas present the operation mode of multiple Touchdown and Liftoff Area (TLOF) pads, and the intersection and overlap of the final approach airspace between two adjacent TOLF pads in the vertiports is the basic problem confronted by multiple TLOF pads. The objective of this study is to design the final approach airspace structure of dual landing pads, so as to provide reference for the future design of the airspace structure of multiple landing pads. In this paper, the design scheme of the final approach airspace of dual TLOF pads is proposed, and it includes three different kinds of airspace structure with different proximity of dual TLOF pads and the final approach path design for each kind based on the multi‐branch approach strategy. Considering the constraints of the multi‐branch approach strategy and safe operation, the airspace design model is constructed to minimize the airspace volume and to develop algorithms that can realize the airspace design with different capacities and different proximity of dual TLOF pads. The results reveal the changing trend of airspace volume under different design capacities and different proximity of dual TLOF pads. It provides reference for the site selection of vertiports with dual TLOF pads, and lays a foundation for the design of the final approach airspace for vertiport with multiple TLOF pads.

“…Tang [19] presented a low-altitude management system (LAMS), which automatically generated a route network with obstacle avoidance capability in low-altitude airspace according to operational requirements such as departure, destination, and flight time. Shao [20] constructed an integrated model based on path planning and distributed sequencing to solve the problem of cooperative scheduling of incoming and outgoing flights by considering dynamics constraints and prioritization. Neto [21] proposed a trajectorybased urban aerial-maneuvering simulate platform capable of evaluating generated paths from the perspective of efficiency and safety.…”

With the continuous opening of low-altitude airspace and the development of aircraft such as electric vertical takeoff and landing (eVTOL) vehicles, urban air traffic has become a sustainable and green development direction for future transportation. Air route networks, as a mainstream design scheme for air traffic, are able to provide prerequisites for eVTOL and other green aircraft to enter urban airspace for safe operation, among which air route planning is a fundamental component of air route network design. Currently, most of the research on aircraft path planning is performed in free airspace, lacking the analysis and processing for the complex operation environment, which has led to the high risk and large operation cost of path planning results, failing to meet the demand for safe and efficient development in the future. Aiming at the above problems, eVTOL-oriented air route planning research was carried out. Firstly, the urban low-altitude airspace structure was planned, and the operational levels of eVTOL were clarified; this was followed by introducing the urban dynamic air–ground risk factors and constructing a dynamic risk assessment model containing risk level information; finally, the improved A* algorithm based on the risk cost was employed to plan the eVTOL air route network, which finally realized the purpose of short path length and low total risk. The simulation results showed that the route generated by the improved A* algorithm could reduce the risk cost by at least 30% with a relatively small path cost, which ensured the operation efficiency and safety of eVTOLs and laid the foundation for the further sustainable and green development of urban airspace in the future.
