| Outline of Annual Research Achievements |
Air traffic inefficiencies lead to excess fuel burn, emissions and air traffic controller (ATCo) workload. Various stakeholders have developed metrics to assess the operation performance. Most metrics compare the actual trajectories to some benchmark ones to calculate excess time or distance. This research is inspired by cellular automata (CA) and develops a combined time-distance lateral inefficiency and predictability metric using discrete space and time mapping on published flight routes. It focuses on Tokyo International Airport, and uses only track data and published routes, which makes it easily applicable to any other hub airport worldwide. The mapping and velocity analyses are used to investigate when and where ATCos are most likely to intervene to provide safe separation.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Other work obligations delayed the progress of the current research.
|
| Strategy for Future Research Activity |
This research introduced how a discrete and spatial mapping inspired from cellular automata can be used to evaluate air traffic predictability and inefficiencies.
Future works include a more detailed investigation of a traffic metric adjustable to the stakeholder’s needs, for example focusing on either traffic predictability, key for trajectory-based operations, or flight efficiency.
The results from the research can be further expanded to investigate the correlation between adverse-weather, new entrants such as supersonic aircraft, and traffic inefficiencies.

| Causes of Carryover |
The research has been granted an extension to JFY2024, so the remaining funds will be used in 2024.
