Research Progress of Air Traffic Complexity

Abstract

Air traffic complexity is the essential attribute of air traffic situation,and it is therefore one of the drivers for air traffic controller′s workload.Scientific evaluation of air traffic complexity is the key to realize air traffic refined management,and is a research hot-spot of air traffic management.The Chinese and global research teams on air traffic complexity is introduced in this paper.The differences and associations of air traffic complexity with workload and safety level are summarized,and the concrete clues in the existing research are elaborated,which are based on control cognitive perspective,geometric structure perspective and complex system perspective and the main contents and relative merits are concluded.The future research trends and directions of air traffic complexity are prospected on the basis of characterization of new-generation air traffic management system.
