摘　　要：扇区容量是空中交通运行管理的基础性参数,目前主要通过管制员工作负荷来评估,由于主观性强、时效性差,只能应用于战略流量管理中.本文尝试从实际雷达数据出发,建立一种新的扇区运行容量计算方法.首先,通过分析雷达数据及交通流特性,将扇区交通流按一定原则划分成5种标准模式,然后利用DTW算法对选取测试序列进行模式匹配,最后统计该模式下扇区最大流量,并定义其为扇区的容量值,从而求出扇区的运行容量.该方法克服了从分析管制员工作负荷入手的主观容量评估面临的障碍,有望成为支持新一代空管系统基于性能运行的关键技术.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.
