Learning Air Traffic as Images: A Deep Convolutional Neural Network for Airspace Operation Complexity Evaluation

Abstract: A sector is a basic unit of airspace whose operation is managed by air traffic controllers. The operation complexity of a sector plays an important role in air traffic management system, such as airspace reconfiguration, air traffic flow management, and allocation of air traffic controller resources. Therefore, accurate evaluation of the sector operation complexity (SOC) is crucial. Considering there are numerous factors that can influence SOC, researchers have proposed several machine learning methods recentl… Show more

“…In addition to the evaluation of the reliability of the models, it is also important to evaluate the performance of the algorithms in terms of resource utilization. ere is very little work evaluating the computational complexity of deep learning models although there is some proposal [84] that considers some factors, such as the number of layers, the size of the input matrix, and other factors depending on the specific algorithm. In CNN, the number and size of convolution kernels and the number of output channels of each layer are considered.…”

“…Radišić et al [21] put forward novel complexity indicators under trajectory-based operation, and Andraši [22] estimated the air traffic complexity using neural networks. Xie et al [23] used images instead of complexity factors to evaluate the operational complexity by deep convolutional neural networks. ty between the two clustering results is analysed to investigate whether there is a correlation between complexity and performance or not.…”

“…The conclusions drawn from these projects are important for the ATC service, as an increasing airspace complexity directly leads to an increase in controllers' workload. [9]. Thus, many benefits can be subtracted from the establishment of a specific complexity measure through allowing a more direct 1226 (2022) 012018 IOP Publishing doi:10.1088/1757-899X/1226/1/012018 2 assessment of the controllers' workload.…”

Due to this relationship between the sector operation complexity (SOC) and controllers' workload, SOC will have an extraordinary role in air traffic management, e.g., airspace reconfiguration, air traffic flow management, and allocation of the ATC service resources [9]. These reasons place the study of complexity as a topic of great interest [10].…”
