| 摘要： | The objective of this research by NextGen AeroSciences, LLC is twofold: (1) to deliver an initial 'toolbox' of algorithms, agent-based structures, and method descriptions for introducing trajectory agency as a methodology for simulating and analyzing airspace states, including bulk properties of large numbers of heterogeneous 4D aircraft trajectories in a test airspace -- while maintaining or increasing system safety; and (2) to use these tools in a test airspace to identify possible phase transition structure to predict when an airspace will approach the limits of its capacity. These 4D trajectories continuously replan their paths in the presence of noise and uncertainty while optimizing performance measures andperforming conflict detection and resolution. In this approach, trajectories are represented as extended objects endowed with pseudopotential, maintaining time and fuel-efficient paths by bending just enough to accommodate separation while remaining inside of performance envelopes. This trajectory-centric approach differs from previous aircraft-centric distributed approaches to deconfliction. The results of this project are the following: (1) we delivered a toolbox of algorithms, agent-based structures and method descriptions as pseudocode; and (2) we corroborated the existence of phase transition structure in simulation with the addition of 'early warning' detected prior to 'full' airspace. This research suggests that airspace 'fullness' can be anticipated and remedied before the airspace becomes unsafe. |
