基于信息熵的城市公交网络模糊评价

Fuzzy Evaluation of Urban Public Traffic Network Based on Information Entropy

利用模糊数学知识对城市公共交通网络系统进行了综合评价。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的评价体系,然后,利用多指标模糊综合评价原理,在确定评价等级的基础上,建立了基于信息熵的城市公交网络的多层次评价模型,该模型将城市公交线网的多层次评价转化为单层评价,比较简明准确地反映出公交线网发展现状。用它对银川市现有公交线网进行了综合评价,结果表明该法科学合理、简单易行。

In this paper, the fuzzy mathematics knowledge is utilized to assess the comprehensive evaluation of urban public traffic network. Having analyzed the elements that influence the network of urban public traffic,we put forward an index system of comprehensive evaluation method and build up a model of multi-factorial fuzzy comprehensive evaluation based on information entropy. It is applied to the practical evaluation of urban public traffic network in Yinchuan city and some positive results were obtained.
