摘　　要：提出了“分类评价指标、构建隶属度矩阵、绘制隶属函数图”的快速公交服务水平模糊分级方法.选取到站时间、等车时间、公交车速度作为评价指标,采用自主开发的公交出行调查系统开展快速公交乘客出行调查,基于调查所获数据采用模糊分级方法建立了快速公交服务水平的模糊分级.与目前国内外使用的硬分级对比后发现:模糊分级消除了清晰的边界,通过隶属度来体现评价指标属于不同服务水平等级的程度,评价指标变化引起的服务水平变化通过隶属度改变得以体现,从而有效地克服了硬分级存在的问题.The method of establishing fuzzy levels of service(LOS)criteria for bus rapid transit(BRT)was developed,whose steps included classifying measures,constructing membership matrix and drawing membership function diagrams.Select arrival time,waiting time and bus speed as evaluation indicators.BRT passenger travel surveys were conducted using a self-developed transit travel survey system.Based on the data collected from the surveys,BRT fuzzy LOS criteria were established using the developed method.Some findings were concluded by comparing the hard LOS criteria currently used worldwide:fuzzy LOS criteria eliminate clear boundaries and use membership to reflect to what extent the measures belong to different LOS grades;the changes of LOS due to the changes of measure values can be reflected by continuous changes of membership,thus fuzzy LOS criteria can avoid the shortcomings of the hard LOS criteria.
