城市轨道交通对于改善城市交通状况、促进区域经济协调发展具有重要意义。在分析既有评价方法的基础上,构建了城市轨道交通项目网络规划评价指标体系。将证据理论引入网络规划方案评价中,提出了一种基于Jousselme证据距离的客观权重确定方法,以修正定性指标的Mass函数,同时利用改进的AHP确定评价指标权重,建立了基于改进AHP和证据理论的综合评价模型。最后结合实例进行了验证计算,结果表明该方法能够直观评价城市轨道交通项目网络规划方案的优劣,切实可行。
Urban rail transit is of great significance for improving urban traffic conditions and promoting the coordinated development of regional economy. Based on the analysis of the existing evaluation methods, the evaluation index system of network planning for urban rail transit project is constructed. Introducing evidence theory into the evaluation of network planning scheme, an objective weight determination method based on Jousselme evidence distance is proposed to modify the Mass function of qualitative indicators, meanwhile, the improved AHP is used to determine the weight of evaluation indicators. Based on the improved AHP and evidence theory Comprehensive evaluation model. Finally, a case study is carried out to verify the calculation. The results show that this method can evaluate the pros and cons of network planning project of urban rail transit project intuitively and practically.
