Structure Evolution And Development Of Multi-mode Passenger Transportation Corridors

Passenger transportation corridor connects major cities and transport hubs, which shares high proportion of passenger transport volume. It is considered as the material base of development of social and economic. Therefore, passenger transportation corridor plays an important role in integrated transport system. However, Chinese main transportation corridors have insufficient capacity for many years. Cooperations and interchanges with each other for multi-modes in passenger transportation corridors have not effectively formed, which results in reduction of transport system's efficiency and service quality. As sustained economic growth and living standard improvement, rapid growth of passenger transport demand results in huge pressure on passenger transportation corridor. Nowadays, the big development period of passenger transport corridor is happening in China, at the same time the economy and technology improvement makes big changes to the transport structure. It has become an important issue for both government and researchers that systematically understanding passenger transport system, analyzing evolution of passenger transportation corridor, and rationally allocating resource.On the basis of full consideration of differences in features and relative service levels of multi-modes in integrated transport network, this paper focus on theory related to passenger transport system and empirical issues of passenger transportation corridor. The main work includes the following aspects.(1) Analyzing the method of types classification based on basic characteristics of passenger transportation corridor, this paper proposed new method of type classification based on level of services and functional characteristics. Also, the effect of geographical conditions, economic development level and political orientation factors on construction and development of passenger transportation corridor is summarized. Dividing evolution of the passenger transportation corridor into four stages, the general trend of development of passenger transportation corridor is pointed out. The case study of typical passenger transportation corridor shows that formation of passenger transportation corridor is highly related to population distribution, economic development and national development strategies.(2) In view of the complex network character of structure, this paper analyzed the topological structure and space form features of passenger transportation corridors by complexity theory and fractal geometry research respectively. As an example of Pearl River Delta passenger corridor, it studied the nodes degree cumulative probability distribution, which could be described well by Weibull distribution. Furthermore, the Passenger Corridor Standard Structure Entropy (PCSSE) is proposed to measure the order degree of passenger corridor. The results show that the smaller value of PCSSE has more orderliness structure and the passenger transportation corridor development process with entropy increase in the condition of no energy complement. Based on the synergetic theory, utility function of topological structure is considered to explain the changing of passenger transportation corridors which is the result of the interaction between short term existence effect and long term existence effect. The case study shows railway transport is the most efficiency, whereas road transport is the most robustness in Pearl River Delta passenger corridor.(3) Considering transport routes in network, this paper proposed coverage intensity of passenger transportation corridor network using concept of fractal geometry and proved fractal feature of Pearl River Delta passenger transportation corridor. The case study of Pearl River Delta passenger transportation corridor shows that road Transport and railway Transport network coverage intensity are1.495and1.050, respectively. Also, it was found that development of passenger transport network coverage intensity is related to reduction of transport cost. Based on analyzing network coverage intensity, it points out problems existed in Pearl River Delta passenger transportation corridor. The results show that development of railway transport network is relatively lagged behind the other modes, which should be made efforts to develop railway transport network. Moreover, transport network connectivity will increase three times after completing construction of railway transport network, resulting highly connectivity between various cities. Meanwhile, standard entropy of railway transport network will increase4.48%; network coverage of railway transport network will increase36.19%, which structure of passenger transportation corridor will be improved significantly, and developed efficiently.(4) This paper inputted potential psychological variable into the competitiveness model of different modes in passenger transport corridors, which were highly related to the complex psychological course of travel choice behavior. On the basis of analysis the psychological course of travel choice behavior of passengers, this paper improved the Logit model, and proposed the method for parameters calibration. With this model, this paper studied the passenger composition of various colonies, which were grouped by the income separately based on statistical data of Guangzhou-Shenzhen passenger corridor. The result shows the share rates of various modes of transport and the target groups of high-speed railway of Guangzhou-Shenzhen passenger corridor. This method can provide theoretical basis for the optimization of share rates of various modes and forecast of passenger flow in transportation corridor.(5) According to the energy consumption and related statistical data, this paper developed weighted model to calculate passenger energy consumption factors of different modes of transport. The results show that passenger energy consumption factors for railway, water and air transport decrease significantly, contrarily, passenger energy consumption factor for road transport increases slightly. Moreover, passenger energy consumption factor for railway transport (excluding high speed railway) is approximately8.64%to that of road transport. If load factor is80%-100%, passenger energy consumption factor for high speed rail is approximately10%to that of air transport. Under the current level of technology and transport load factors, railway transport is proved as the most energy-efficient transport mode than others. In order to realize the maximum development of social and economics with minimum energy consumption, this paper makes a proposal to develop multi-modes passenger transport corridor by rationally allocating the resources.
