The Study Of The Network Of Tianjin Public Transportation

Complex network is a new research point in the last few years, Scientists found that more and real networks had the characteristics of complex network, They worked a lot on the models.Traffic networks play an important role in our lives. The design and construction of traffic network have a concernful effect on the traveling of humans.The public traffic network is an important part of traffic networks. We construct the stop complex network model and the line complex network model of public traffic network according to actual public data of Tianjin. The two model reflect the nature topology charater and reachable of public traffic network. Having processed and computed static characteristica data based on Matlab 7.0 software, the study degree distribution and average path length of network. We find that Tianjin public transportation is a scale-free network in the the stop complex network model, but in the line complex network model is a Random network, In addition to, we also find that it is also a small-world network in the line complex network model, the reason is that it shows lower shortest path.These analysis play a very important role in planning the layout of Tianjin public transportation.
