基于不同构型的航路网络节点通行能力研究

Research on capacity of air route network node based on different configurations

为提高航路网络的运行安全和效率,确定空中交通瓶颈,提出了航路网络节点通行能力的概念.结合空中交通管制运行安全条件,研究了多条航段和不同交通流走向相结合所形成的发散、汇聚、转弯和交叉四种节点构型的通行能力.以中国大陆空域为例,根据航线走向,基于飞行计划,计算了全空域1 556个节点的通行能力和交通量,确定了93个瓶颈节点的位置以及拥堵程度,给出了拥堵最严重的3个节点和4个飞行情报区域,提出了提高节点通行能力的方法.

In order to improve safety and efficiency of air traffic and confirm air traffic network node bottleneck, the concept of air route network node capacity was introduced. According to the operation safety conditions, the capacity of different configuration nodes formed by multiple segments and different direction of traffic flow were studied, including divergence, convergence, turning and crossing. As China mainland air area for example, according to flight plan and the direction of air routes, confirmed the location, quantity and congestion of 93 nodes, provided 3 most congested nodes and 4 flight information regions and put forward the method to improve the node capacity.
