Abstract:

The controller workload is the main factor affecting the airspace capacity. To balance controller workload,reduce regulatory pressure and increase airspace capacity,a sector plan method based on weighted Voronoi diagram is proposed. This method is applied to determine the basic sector unit of the airspace sector,unlike the previous subjective measuring method,sector planning model is established based on complexity equalization principle,then using the growing algorithm to optimize combination of airspace sector units,ultimately the optimal sector boundary is found. And through the simulation of actual data in Xiamen low altitude controlled airspace,the results verify the rationality of the proposed sector boundary demarcation method.

Key words: weighted Voronoi diagram, air traffic complexity, growing algorithm, sector boundary
