基于非负矩阵分解的城市公交网络综合评价模型

针对城市公交网络的评价问题,在综合考虑城市公交系统诸多因素的基础上,建立了城市公交网络系统的综合评价指标体系。然后利用非负矩阵分解的知识,提取出指标体系中的主要综合性指标。通过对银川市现有的公交网络进行综合评价后发现,文中所提出的方法可以克服传统的评价方法结果无明确几何意义和主观依赖性等缺点,从而可以更为有效的给出量化的评价结果。

Comprehensive evaluation model of public transit network based on Non-negative matrix factorization

Directing at the evaluation of urban public traffic network,based on the comprehensive consideration of elements that influence the urban traffic system,a index system of comprehensive evaluation is put forward.Then extract the main comprehensive index of the index system,using the knowledge of Non-negative Matrix Factorization.Through applying on current public traffic network of Yinchuan,we assure that the method proposed in this paper could overcome the shortage of undefined geometric meaning and subjective dependence in traditional evaluation method,which can be more effective in leading to quantitative evaluation results.
