摘　　要：为验证HOV车道的实施效果,从社会经济、交通效率、环境影响、出行满意度4个方面构建了综合效益评价指标体系,并对各项指标进行了定义,运用熵权法确定了指标权重。结合道路交通评价标准,确立了各项评价指标的隶属度,并建立了指标的梯形隶属度函数。运用模糊数学原理,构建了模糊综合评价模型。以成都市为例,对已推行HOV车道的运行现状进行了调研,结合模糊综合评价模型,得到了HOV车道的综合效益评价值。结果显示:天府大道南段的HOV车道运行效益最优,科华南路的HOV车道运行较为稳定,此两路段的综合运行效益评价结果均为良好,剑南大道HOV车道运行效益较差,综合运行效益评价结果为一般,且3个路段HOV车道的早高峰综合运行效益评价值优于晚高峰;同时,对比同路段的HOV车道和普通车道,科华南路、剑南大道HOV车道的综合效益优于普通车道,改善效果明显,天府大道南段HOV车道和普通车道的综合效益相差不大,设置必要性不突出。最后,分析了现行HOV车道方案存在的问题与局限,从准入条件、设置HOV车道类型、区间长度、运行监管等方面提出了建议和对策,以进一步提高HOV车道的公众满意度。To verify the implementation effect of HOV lanes,a comprehensive benefit evaluation indicator system is constructed from the aspects of social economy,traffic efficiency,environmental influence and travel satisfaction,and each indicator is defined,and each indicator weight is determined by entropy weight method.The membership degree of each evaluation indicator is established in combination with the road traffic evaluation standard,and the trapezoidal membership function of the indicators is established.A fuzzy comprehensive evaluation model is built by the principle of fuzzy mathematics.Taking Chengdu City for example,the operation status of the existing HOV lanes is investigated,and the comprehensive benefit evaluation value of the HOV lane is obtained by combining the fuzzy comprehensive evaluation model.The result shows that(1)The operation efficiency of the HOV lane of south Tianfu Avenue is the best,and the operation efficiency of HOV lane of Kehua South Road is relatively stable.The comprehensive operation benefit evaluation result of these 2 sections are all good.The operation benefit of the HOV lane of Jiannan Avenue is poor,and its comprehensive operation benefit evaluation result is general.The comprehensive operation benefit evaluation values of the HOV lanes of the 3 sections in the morning rush hour are better than those in the evening rush hour.(2)At the same time,comparing HOV lanes and common lanes of the same section,the comprehensive benefits of HOV lanes of Kehua Road and Jiannan Avenue are better than those of common lanes,the improvement effect is obvious.The comprehensive benefits of HOV lanes and common lanes of Tianfu Avenue are not much different,and the necessity of setting HOV lanes is not prominent.Finally,the existing problems and limitations of the current HOV lane scheme are analyzed,and the suggestions and countermeasures are put forward from the aspects of access condition,setting type of HOV lanes,interval length,operation supervision,so as to further improve the public satisfac
