Review of complex network theory based researches on public transit system network

With the development of city, all kinds of vehicles, especially private cars which are dramatically increased, traffic problems become more and more serious than ever before. In recent years, all kinds of efforts has been made to reveal the structure features of public transit system. Some basic structure features in transit network, for example, the analysis of statistic characteristics, the calculation of negotiability and the identifications of fragile nodes become more complex with the scale of network getting larger, so researchers across the world put forward kinds of methods to solve the problem. This article reviewed the complex network theory based researches on public transit system, discussed the problems about public transit network from the application aspect to provide a whole picture about the art of fact.
