基于模糊逻辑的驾驶员路线选择行为分析

鉴于路线选择过程中驾驶员行为普遍存在的模糊性,基于模糊逻辑的分析方法,针对驾驶员的路线选择行为进行了研究。所建立的路线选择模型中,将驾驶员对路线行驶时间、距离以及安全性等指标的感知进行了模糊化处理,进而建立了解模糊化规则,并采用层次分析的推理方法对可选路线进行两两对比。在对比矩阵的基础上可计算路线各个性能的权重,进而得到路线被选择的概率。案例分析的结果表明,该模型能够有效解释驾驶员对路线的模糊感知,为驾驶员短期选择行为分析提供了一种新方法。

A Study of Driver's Route Choice Behavior Based on Fuzzy Logic Method

In view of the uncertain characteristics involved in the process of driver's route choice,the driver's route choice behavior based is studied on fuzzy logic method.In the presented model,the driver' s perception of travel time,distance,safety of routes are fuzzified,moreover the defuzzification rules are constructed,also the routes were compared pairwise by approximate reasoning method,then on the basis of the comparison matrix,the weight of the routes can be calculated,at last the choice possibilities of r...
