【摘要】 以服务水平分析为手段,对道路交通拥挤程度进行分析,并提出应用模糊逻辑量化交通状态的方法。采用了行程速度与流量两个因素为输人变量,建立相应的模糊推理规则体系,得到了交通状态量化判断曲面定义交通状态6个等级。基于模糊聚类方法的服务水平分级标准,能更全面反映城市道路连续交通流的交通特征,有助于提高交通管理决策水平以及提供更优质的交通信息服务。更多还原

【Abstract】 Using service level analysis,the paper studies the degree of traffic conjestion and proposes the quantitative method in traffic condition study through fuzzy logic,which goes as this: taking travel speed and traffic volume as input variables,establishing the corresponding fuzzy inference rule system,and obtaining the six levels of traffic soundness judged from the quantitative curve of traffic conditions.更多还原
