为改进航空器计量方法在评估交通态势复杂度时的局限性，本文建立了一种空中交通复杂性评估模型.基于空中交通的结构因素，模型构建了距离因子和冲突因子，能够反映航空器之间的相对距离与航迹交叉作用对于复杂性的影响.针对广州区域扇区进行的交通复杂性指标评估结果表明：航空器数量的变化会引起目标空域交通复杂性的变化，但后者对前者的响应并非完全同步；两者的变化程度不完全相同，且变化趋势可能相反.对相应交通态势的回溯和分析表明，相比基于航空器数量的评估方法，交通复杂性指标能够更加客观地反映空域状态的变化特征.

Traffic Structure-Based Air Traffic Complexity Modeling

To overcome the limitations of traditional evaluation methods which based on aircraft counts in assessing complexity of the air traffic situations,the paper develops a new air traffic complexity model based on structure factors.With analysis of air traffic control difficulty effects from the potential conflicts due to traffic structure factors such as the relative distance of aircraft pair-wise and the intersecting trajectory,the paper considers distance factor and the conflict factors in the model.Assessments based on the operational data from Guangzhou area control center in China indicate that the traffic complexity values vary as aircraft counts change all the time.However,the extending of the change is not the same and the tendency is even opposite sometimes.Replay and further analysis of the traffic situations validate the model that the new metric ensitively and accurately reflects the operational characteristics of the airspace compared by aircraft counts-based methods.
