Research On The Evolvement Mechanism And Optimization Method Of Urban Passenger Transport Structure

Urban public passenger transport is an important component of passenger transport in urban, and is the inevitable product of socio-economic development. It contacts social production, circulation and people's living. The cities in China are in motorization and urbanization, and being in rapid development stage, the structural evolution of urban public passenger transport is also at a critical stage. Comprehensive outer circumstances and internal evolution factors analysis, overall public passenger transport development strategy and urban public passenger transport regulatory policy decided future urban passenger transport sustainable development. This paper mainly research the traffic structure of urban public passenger transport with Dissipative Structure Theory (DST) and economics theory, discussing the urban public passenger transport structure evolution and optimization issues when urbanization, motorization and urban resident's willing is changing, and studying urban passenger transport sustainable development, reasoning use and resources distribution to promote urban economic, urban public transport and social environment in coordinated way. These problems have been important issues which need to be resolved today in China.Reasonable urban public passenger transport function orientation reflected urban passenger transport development strategy. This paper mainly researches the function positioning of the passenger transport within the public passenger transport system. It will directly affect the evolution of the structure of the urban public transport. Reasonable set of different types of urban public passenger transport modes function should be established with socio-economic development in cities at different stages. Especially reasonable rapid transit with the orbital transport functions not only directly affect urban passenger transport system of the current year and future planning of public transport modes trends, but it can also contribute to urban rational allocation of the limited resources and improving the efficient use of time and space resources.Urban socio-economic, transport policy, urban spatial distribution, transport infrastructure level, geographical environment and resident's psychological , customs and standards of living and other factors determine the impact of these issues, also affect the formation of urban public passenger transport structure evolution. This paper studies the system structure evolution through overall outer circumstances and internal evolution factors analysis. There are four classification outer circumstances such as economy, system, technique and passenger transport market and their role in the evolution of different classification structure studied. All of these circumstances would affect the supply and demand characteristic of urban public passenger transport, and also affected the scale and assignment of passenger traffic flow. These effects would be exposed to partner's behavior and characteristic of public passenger transport system. At the internal factors analysis, paper mainly discusses the characteristics of urban residents and public passenger transport participants (passengers, operators and managers) economic characteristics through economical theory. Especially, the opportunity costs, external costs, social benefits analysis of the urban public passenger traffic managers would be deeply reflected the courses of the optimization of the structural evolution of micro-dynamics.To analysis urban public passenger transport system inner interactions and system architecture evolution trend, this paper considered public passenger traffic flow as a state variables, established public passenger traffic flow competition and coordination evolution models, basing on some method of DST and passenger transport system structure evolution. By using simulation method with matlab, this research analyses passenger transport structure evolution trends of the big city of our country in different parameters, and more coordinated manner conditions. Simulation analysis shows that in China's large cities limited traffic resources conditions, large-capacity rapid public passenger transport system reasonable size,...
