As there are uncertainties in the public transportation network optimization evaluation process, many existing methods cannot simultaneously describe the uncertainties in different types and therefore will result in an un-objective reflection of the actual problem. In this paper set-pair and entropy analysis is used to analyze the internal connections of the system globally and locally. This model which is simple in calculation and easy to use has theoretical and practical values for new ideas and methods of uncertainty analysis of the public transportation network optimization.

Urban public transportation contributes greatly to sustainable urban development. An urban public transportation network is a complex system. It is meaningful for theory and practice to analyze the topological structure of an urban public transportation network and explore the spatial structure of an urban transportation network so as to mitigate and prevent traffic congestion and achieve sustainability. By examining the Xi’an bus network, the degree distribution, average path length, aggregation coefficient, and betweenness centrality of the bus station network were computed using models in complex network theory. The results show that the node degrees of the Xi’an bus network are unevenly distributed and present a polarization diagram with long average path length and high aggregation. A model based on betweenness and its solution method was developed to improve the public transportation network’s sustainability and discuss the possibility of optimizing the sustainability by network analyzing methods.
