基于集对分析的道路交通拥堵判定

基于集对分析原理提出了道路交通拥堵判定的新方法——集对分析法,给出了集对分析法的基本思路和交通拥堵判定步骤。该方法考虑了交通状态分级标准的模糊性,同时避免了差异不确定系数的取值,应用于成都市某路段交通拥堵状态的判定,结果表明,该方法概念清晰、结构简单、计算简单、易操作、可行有效。

Traffic Congestion Judgment based on Set Pair Analysis

This paper puts forward a new method about traffic congestion judgment based on set pair analysis principle, which is set pair analysis, and gives the basic idea and steps of the set pair analysis method. The method takes into account fuzzy of traffic state classification standard, while avoiding the problem of difference uncertainty coefficient, is applied in judgement of Chengdu city traffic congestion state. The results show that, the method is clear in concept, simple structure, easy operation, simple calculation, feasible and effective.
