基于几何航路汇聚点设置的骨干航路网络规划

Plan of backbone air route network based on route crossing waypoint setting by geometric method

由于空中流量需求越来越大,目前的航路网络难以适应航空运输发展。针对中国空域现状,探讨了中国骨干航路网络的规划问题。在规划中首先筛选枢纽机场及中国7个国境点作为国内骨干航路网络的节点。然后,通过对这些节点间的航路流量、角度、禁区限制等条件进行合并、优化,并利用几何方式设置航路汇聚点,从而优化航路性能。最终得到一个全国骨干航路网络的设计方案。

As the air traffic demand is growing quickly, the current air route network should be adjusted to accommodate the development of air transportation. The design of the backbone air route network is discussed based on the airspace of China. The backbone air route network is the one which meets the gradually growing aviation business. Firstly, several hub airports and seven border points are selected as the nodes in the backbone route network. After the hub nodes are selected, the air routes between these nodes are optimized by some conditions such as air traffic flow, angle, etc. Then some route crossing waypoints are set to further optimize the network performance. The sum of distance between the waypoint to the hub airports in the zone is shortest. After the prohibited zones in our airspace are considered, one backbone route network plan has been given at last.
