A Metric for Air Traffic Complexity
As ATM system has become more congested with proliferated demands, and preferred trajectories own higher priorities than before, its necessary to develop integrated metrics for daily operation. To gain insight of the traffic orderly status, the paper proposes a multi dimensional complexity metric focusing on the unsymmetrical effects imposed by the inter-relationship emerged among the multi-aircraft pair-wise. The proximity effects on the individual aircraft based on the single-aircraft and multiaircraft pair-wise are modeled and the difference between them inspires us to present the synchronization structure of the traffic considering the traffic patterns in controllers minds. Then a new metric for traffic complexity is set up and initially validated under typical static traffic situations. We find its good for revealing the availability of shady airspace, so two kinds of reroute strategies with corresponding simulation scenarios are discussed. Its easy to excavate the potential airspace capacity with the metric and both the heading and the clearance of the interval period adjusting strategies can be found maintaining acceptable complexity level as well, which implies the application field of the new metric for future dynamic ASM and ATFM.
