Abstract:

Sector capacity is a fundamental parameter for air traffic operation management, whose evaluation methods based on controller workload. It can only be applied in strategic flow management so far for its strong subjective nature and poor timeliness. This paper attempts to establish a new calculation method of the sector operating capacity on the basis of the actual radar data. First, through the analysis of radar data and the characteristics of traffic flow, traffic flow of sector could be divided into five standard modes based on certain principles. Then match the selected test sequence with the DTW algorithm. Finally, we count the maximum flow of sector in this mode and define it as the capacity of sector. Thereby we can get the sector operating capacity. This method overcomes the barriers that current subjective capacity evaluation methods face by starting from analyzing controller workload. It is a potential key technology supporting performance based operation of the new-generation ATM system.
