摘要
终端区交通态势的准确度量是制定并实施流量管理措施的重要依据之一。通过提取终端区宏观与微观的交通特性,从进离场及总量3个维度构建态势的指标描述,并进一步采用中介理论中的真值程度度量与熵权法建立了一种客观的终端区飞行区交通态势模糊综合评价方法,实现客观、准确的交通态势判别与样本间量化比较。选取国内典型繁忙终端区的实测数据,验证了评价方法与特性指标的有效性。
Accurate evaluation of traffic situation in terminal area is an essential content for traffic management strategy making and implementation. In this paper,a set of macroscopic and microscopic traffic characteristics were extracted to build the description of traffic situation from 3 dimensions. Further,a fuzzy comprehensive evaluation method based on measure of medium truth degree and entropy theory was introduced to calculate and classify the traffic situation of terminal area objectively. Taking a typical busy terminal area in China as example,the effectiveness of the proposed method and traffic characteristics were verified.
