摘要
空中交通态势的识别与预测是当前研究热点之一。在分析态势概念的基础上,建立了空中交通态势的评估指标体系,引入洛伦茨曲线与基尼系数对机场平均起飞延误分布的不均衡度这一重要指标进行研究。通过实际数据的计算和分析,验证了洛伦茨曲线在延误不均衡度分析中的有效性和可行性。
Identification and prediction of the air traffic situation is one of the current research focuses. In this paper, evaluation index system of an air traffic situation is constructed based on the concept of situation, and the unbalanced situation of takeoff average delay is studied based on the Lorenz curve and Gini coefficient. Finally the effectiveness and feasibility of the method is illustrated with an example.
