随着美国国家空域系统（NAS）的拥挤程度增加，协调航路和终端区的交通流量管理程序变得越来越必要，以防止管制员工作量过大，同时又不对飞机造成过多的延误。在这里，我们通过开发一系列可实现的流量限制的抽象来解决存在现实不确定性的流量管理程序的协调问题（例如，里程限制、地面延误计划和基于时隙的政策）。使用这些抽象，我们能够评估多个限制通用（不确定）的交通流量的影响，因此，设计实用的流量管理策略。我们使用开发的方法来解决几个常见的设计问题，包括设计的多个限制沿着一个主要的交通流和设计的多个流量进入一个拥挤的终端区域或部门。例如，我们发现，多个限制沿着一个流可以被用来分裂的积压从一个单一的限制，并使用此观察开发低拥塞的设计。最后，我们提出了一个易于处理的NAS范围内的流量管理问题，使用一个简单的代数模型的限制的讨论。
As congestion in the United States National Airspace System (NAS) increases, coordination of en route and terminal-area traffic flow management procedures is becoming increasingly necessary to prevent controller workload excesses without imposing excessive delay on aircraft. Here, we address the coordination of flow management procedures in the presence of realistic uncertainties by developing a family of abstractions for implementable flow restrictions (e.g., miles-in-trail restrictions, ground delay programs, and slot-based policies). Using these abstractions, we are able to evaluate the impact of multiple restrictions on generic (uncertain) traffic flows and, hence, to design practical flow management strategies. We use the developed methodology to address several common design problems, including the design of multiple restrictions along a single major traffic stream and the design of multiple flows entering a congested terminal area or sector. For instance, we find that multiple restrictions along a stream can be used to split the backlog resulting from a single restriction and use this observation to develop low-congestion designs. We conclude the discussion by posing a tractable NAS-wide flow management problem using a simple algebraic model for a restriction.
