基于单向循环航路网规划的航路交叉点及航段容量模型研究

Research on Route Crossing Point and Route Segment Capacity Models Based on One-way Loop Route

随着航空运输业的高速发展,有限的空域资源已越来越不能满足需求,使得空中交通日益拥挤,迫切需要一种新型的空域结构来缓解当前空中交通出现的问题。为更深入地认识单向航路,首先阐述了单向航路的基本概念和特点,然后进行了量化的分析。针对单向航路和混合航路两种情况,分别建立了相应的交叉点容量的计算模型。随后对单向航路和混合航路中有穿越情况的航段容量进行建模。最后以京昆大通道上某个交叉点为例,使用Matlab软件编程进行算例仿真。仿真结果表明,单向航路上的交叉点容量和有穿越情况的航段容量均要大于混合航路,在一定程度提高了运行容量。

With the rapid development of aviation transportation, the limited airspace resource becomes more and more congested. It is urgent to find a new type of airspace structure to mitigate the currentl issues of air traffic. In order to understand one-way route, the concept and characteristics of one-way route are introduced firstly. Then elaborate analyses are conducted quantitatively. Aiming at one-way route and mix-way route, route crossing point region capacity models are designed, and then the route capacity is modeled in situation of changing flight levels. Finally, a crossing point in Jingkun route is taken to simulate these models and Matlab is also used to calculate them. It is finally con- cluded that capacities of one-way route is more than the capacities of mix-route, so one-way route can increase route crossing point region and route segment capacities to some extent.
