摘要
选用饱和度、平均停车延误、排队长度、干扰率、人车分离度等作为评价指标,将灰色聚类与模糊聚类分析方法相结合对我国城市混合交通状态下的信号交叉口综合质量进行评价分类,并对聚类结果进行分析比较。结果表明,基于灰关联度的动态聚类分析方法简单可靠,能科学评价交叉口的综合质量。
For the sake of evaluating the comprehensive quality of urban signal intersections in China under mixed traffic conditions, this paper selects the saturation degree, the average stop delay, the queue length, the interference ratio and the separation ratio as the evaluation indexes and compares the clustering results by means of combining the grey clustering with the fuzzy clustering analysis method. The results show that the dynamic clustering analysis method based on the grey relation degree is simple and reliable and can provide the scientific evaluation of the comprehensive quality of intersections.
