摘要 研究中小城市综合交通网络的评价体系,为中小城市综合交通网络的合理规划提供理论依据。该研究从规模、结构、服务水平和布局4个层面进行评价,采用相关系数法筛选出符合中小城市交通发展特征的指标,建立综合评价指标体系。基于模糊综合评价法和直线型无量纲法,对定性和定量指标进行量化处理。为了提高赋权的准确性,考虑多位决策者的评价意见,采取贝叶斯BWM进行组合赋权,最后结合价值分析法和灰色关联分析法计算综合评价值。研究结果表明:本研究提出的综合评价体系能够全面评价中小城市的综合交通网络,对当前各交通模式中存在的问题进行讨论,并基于此提出未来交通规划的相关建议。 Study the comprehensive evaluation(CE)system of integrated transportation network(ITN)in small and medium-sized cities to provide theoretical basis for rational planning of comprehensive transportation network in small and medium-sized cities.Based on four aspects of scale,structure,service level,and layout,this study used the correlation coefficient method to select indicators that meet the characteristics of transportation development in small and medium-sized cities,and established a CE indicator system.Built upon that,fuzzy comprehensive evaluation method and linear dimensionless were applied to quantify and nondimensionalize the qualitative and quantitative indexes.In order to improve the accuracy of weighting,Bayesian BWM is adopted to get the index weight considering the references of different decision makers.Finally,the combination of value analysis(VA)and grey relational analysis(GRA)was used to calculate the CE value.The results show that the introduced CE framework can offer a thorough evaluation of the ITN in small and medium-sized cities.Then,the problems existing in different transportation modes is discussed and relevant suggestions are provided for future traffic planning.
