摘要

为实现基于轨迹作战(TBO)环境下的自主空中交通管理(ATM),提出了一种支持同步空地态势感知的受限自由航路空域(FRA)两阶段实时自主四维轨迹冲突检测与解决方法。采用元胞概念进行空域离散化,以平衡精度和计算成本。在第一阶段,通过在基于入口点和出口点以及空域内每个限制区域的边界点构建的网络中搜索路径来生成每个即将到来的航班的期望轨迹。在第二阶段,为了避免飞行过程中的冲突,引入了能够对管制员和飞行员的冲突情况进行可视化的时空棱镜模型,在考虑控制到达时间(CTA)的情况下,生成可行的无冲突轨迹。以中国西部某典型航路部门为例,验证了该方法的有效性。最后,从计算成本和操作效率的角度研究了细胞尺寸的敏感性。结果表明,本文提出的自动轨迹规划是未来自动ATM系统的一种很有前途的解决方案。

Real-Time Autonomous Trajectory Conflict Detection and Resolution in Restricted Airspace
Aiming at achieving the autonomous Air Traffic Management (ATM) in the Trajectory-Based Operation (TBO) context, a two-stage real-time autonomous four-dimensional trajectory conflict detection and resolution method in restricted Free Route Airspace (FRA) supporting the synchronized air-ground situational awareness was proposed. Cellular concept was used for airspace discretization to balance the accuracy and computation cost. At stage one, the desired trajectory for each upcoming flight is generated by searching a path in a network constructed based on the entry and exit point, as well as boundary points of each restricted area inside the airspace. At stage two, in order to avoid conflict during travelling, the Space-Time Prism model, which is capable of visualizing the conflict situation for both controllers and pilots, is introduced to generate the feasible conflict-free trajectories while keeping the Controlled Time of Arrival (CTA) in mind. A case study based on a typical en route sector in Western China was carried out to test the effectiveness of the proposed method. In the end, sensitivity of cell size was investigated in terms of computational cost and operational efficiency. Results showed that the proposed autonomous trajectory planning would be a promising solution for future autonomous ATM system.
