Airspace complexity is a critical metric in current Air Traffic Management systems for
indicating the security degree of airspace operations. Airspace complexity can be affected …

Airspace complexity is a key indicator that reflects the safety of airspace operations in air
traffic management systems. Furthermore, to achieve efficient air traffic control, it is …

Air traffic complexity is an essential indicator to evaluate the air traffic situation within one
given airspace, with respect to both the workload of traffic control and the degree of …

A sector is a component airspace whose operation is allocated to an air traffic controller. The
operation complexity of a sector plays a critical role in the current Air Traffic Management …

Air traffic complexity, which measures the disorder of air traffic distribution, has become the
critical indicator to reflect air traffic controller workload in air traffic management (ATM) …

Airspace complexity is defined as an essential indicator to comprehensively measure the
safety of air traffic operational situations. A reliable prediction of airspace complexity can …

Air traffic complexity is an objective metric for evaluating the operational condition of the
airspace. It has several applications, such as airspace design and traffic flow management …

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 …

This paper presents an original method to evaluate air traffic complexity metrics. In previous
works, we applied a Principal Component Analysis (PCA) to find the correlations among a …

Today, aircraft demand is exceeding the capacity of the Air Traffic Control (ATC) system. As
a result, airspace is becoming a very complex environment to control. The complexity of …
