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.
In order to improve the limitation of aircraft measurement method in assessing the complexity of traffic situation, this paper establishes a model of air traffic complexity assessment.Based on the structural factors of air traffic, the model builds the distance and conflict factors, Relative Distance and Track Crossing Influence on Complexity The evaluation of traffic complexity index for Guangzhou regional sector shows that the change of aircraft quantity will cause the change of traffic complexity of target airspace but the latter’s response to the former is not And the trend of change is opposite.Retrospective and analysis of the corresponding traffic situation shows that the traffic complexity index can more objectively reflect the change of airspace status than the assessment method based on the number of aircraft feature.
