摘　　要：借鉴定性推理中的相关概念和方法,本文尝试提出一种新的为宏观交通流定性建模的方法、在定义了交通参数的定性状态和定性关系等概念的基础上,本文以北京三环路的实际交通流为例,说明了宏观交通流定性建模的过程,其中在确定参数的定量空间时用到了小波分析方法。Referring to the concepts and ideas of qualitative reasoning, a tentative modeling method to traffic flow characteristics is proposed in this paper. Based on the definitions such as qualitative states and qualitative relationships of traffic parameters, an actual traffic system ?Beijing Third-cycle-road(BTCR)is taken as an example to illustrate the process of modeling, In particular, the wavelet analysis is employed to determine the landmarks of traffic parameters.
