Air Traffic Service Route Network Analysis to Support Local Traffic

The network of air traffic service (ATS) routes is the main component of the modern air transportation system. Configuration of ATS routes is responsible for effective airspace usage. However, a dense network with higher order and big size will be difficult to support air traffic management. Therefore, in most cases during airspace design, it is important to search effective combination of peak air traffic flow and network configuration to distribute nodes load. In the paper, we study ATS routes configuration to support traffic between local airports. We consider ATS route network as an undirected graph. Airports are endpoints of local connections. Graph of runways is connected to the graph of ATS routes by standard schemes of departure, arrival, and approach. We use the shortest path between any two airports to estimate the importance of each waypoint. The excessive value of betweenness centrality for a particular node may indicate its overloading during air traffic simulation with equal flow for different directions. As an example, we use the Ukrainian ATS route network to estimate its configuration and the possibility to support local air traffic.
