摘要:随着航空运输的快速发展,有限的空域变得越来越拥挤,空中高速路设计有助于提高空域使用效率,增加容量。空中高速路的运行在微观上符合跟驰现象。本文在原有研究的基础上,建立了空中高速路流量动力学模型,并通过实例分析,得到了航路流量密度与飞机飞行速度之间的关系,以及管制员负荷对于飞机安全的影响,并对航路中存在的堵塞和疏导现象进行了模拟仿真。本文通过理论推导和实例仿真,得出的最终结果表明,航路流量密度的增大,会导致飞机速度逐渐减小,同时当航路中出现阻塞现象时,有效地疏导行为可以减小航路流量密度和增大飞机速度。

The research of Macroscopic traffic model in air highway
Abstract:With the rapid development of air transportation, the limited airspace becomes more and more crowded, the design of air highway is helpful to improve the using efficiency of airspace and increase capacity. The air flow in air highway meets the following phenomena. In this paper, based on the original research, the fluid mechanics model is established to study the route flow, the relationship between the route flow density and flight velocity is achieved through the example analysis, the influence of controller load on airplane safety is obtained, the blocking and dredging phenomenon are simulated. In this paper, through theoretical derivation and simulation,the result shows that increased airway flow density will cause the aircraft velocity decreases. Meanwhile,when the route is blocking, effectively grooming behavior can reduce route traffic density and increase the speed of the aircraft.
Keywords: air transportation air highway the fluid mechanics model flow density controller load
