Investigation of user selection criteria of airspace design algorithms for the flexible airspace management concept

• Benefits Metrics: Measure of effectiveness in addressing traffic imbalance 1. Number of removed flights [Consistent] 2. Air traffic control resource utilization [Consistent] • Airspace Design Quality Metrics: Measure of “goodness” of the airspace 3. Airspace similarity [Not Consistent] 4. Number of flights with short dwell time [Not Consistent] 5. Distance between traffic crossing points and airspace boundary [Partially Consistent]
