基于管型空域配置的交通复杂性管理

空域的动态配置能力将为空中交通管理提供异质的空域框架,主动适应空中交通增长的复杂特性。管型空域是在繁忙区域中建立的低交通阻抗通道,是实现空域动态配置能力的重要途径和主要研究方向。就转变的空域/交通适应性关系分析了配置管型空域的必要性,分别建立了基本型管型空域模型与增强型管型空域模型。采用基于连携性的交通复杂性测度指标作为空域性能的评价基础,相比无约束的运行空域,管型空域可在维持相同流量的条件下显著降低空中交通的复杂性。针对两类管型空域模型,讨论了基于流调配的交通复杂性管理策略。多向管型空域中各单向管型空域的交通特征显著分化,因此,相应的交通复杂性管理策略须建立在对各管运行情况细致分析的基础上,才能实现交通吞吐量与其复杂性间的最佳权衡。

Air Traffic Complexity Management in with Tube-type Airspace Configuration

The ability of dynamic airspace configuration provides a heterogeneous airspace framework for proactively dealing with increasing complexity of air traffic in air transportation system.As one of effective ways to increase that ability,the tube-type airspace allocation provides a low traffic-resistant corridor within dense airspace.We analyze the adaptable interaction between airspace and traffic behavior under high density operation environment.A basic tube model and an enhanced tube model were developed,and are used to discuss complexity management strategies based on the traffic flow adjustment and alliance effects related air traffic complexity metric.Simulation results indicate the tube is more suitable for future operation in air traffic management for its capability to accommodate higher air traffic with lower complexity compared by the unconstraint airspace.There exist distinct characteristics among different single tubes in the enhanced tube model,so that a trade-off decision between both throughputs of the airspace and the complexity thereof may be accomplished by specific complexity management strategies with exact analysis subject to the operational states of each tube.The results provide an acceptable and feasible way to accomplish dynamic airspace configuration.
