Analysis Of Passenger System Structure Of Regional Comprehensive Transportation Corridor

Regional economic integration, the acceleration of urbanization process, the formation of urban agglomeration and metropolitan region and the boosting of urban and rural integration promote the formation of regional integration.To satisfy the demand of regional integration, firstly, integration of regional transportation must be realized. That is to say, regional transportation must break administrative boundaries, department boundaries and space boundaries. It should unify the programming, management, organisation and dispatching of the whole transportation resourses in the region to build regional comprehensive transportation system and make transportation play a fully dynamic role in the development of economy. Transportation resourses in the region include trasportation vehicles, facilities and related information. In the system of regional comprehensive transportation system, comprehensive transportation corridors are the key of its construction. It is not only the precondition of the realization of the system's benefits, but also affects the efficiency of investment. Based on this background, this paper does reasearch on travel behavior anlysis, structure configuration, rationality and coordination of the structure and some other related questions within passenger system of the comprehensive transportation corridor.1. Based on the analysis of the concept and elements of transportation corridor, the characteristics and analysis of the concept of regional economy, regional economic integration and regional transportation integration, this paper identifies the passenger system of regional comprehensive transportation corridor from the angle of spatial scope, service objects and transportation modes. This paper points out that the passenger system of regional comprehensive transportation corridor is corridor that serves within the scopes of urban agglomeration and metropolitan region, which is composed by different kinds of transportation modes within a narrow area.2. In this paper, the author analyzed the whole travel process of regional comprehensive transportation corridors, and divided the process into five stages, origin access, origin transferation, regional travel, destination transferration and destination access, which can be combined into thress process of acess, transferation and regional travel. The process of acess and transferation are important factors to the choice trip modes in regional travel process. In accordance with the characteristic of reginal trip modes, multi-nomial Logit(MNL), nested Logit(NL) and PCL mode are introduced in this paper to establish six models that are used to analyze the trip behavior of reginal comprehensive transportation corridor. On this basis, the advantages and disadvantages of each model are analyzed. The advantages of MNL is simple structure and broad adaptability, the disadvantage is it cann't avoid the independence of irrelevant alternative(IIA); The advantages of NL is it can avoid the independence of irrelevant alternative(IIA), the disadvantage is complex structure and; The PCL model takes on a better practicability and can solve the problem of IIA.3. In order to segment passenger market of regional comprehensive transportation corridor, Factor analysis is introduced to reduce the dimensions of the variables that affect market segmentation and reduce the number of factors and correlation of different factors. On this basis, the theory of correspondence analysis is introduced to analyze the correspondence relations of different impact factors. The graph of correspondence analysis is obtained, through which distribution of different impact factors of passenger market is clearly revealed. In order to calculate the substitutability of regional integrated transport corridor between passenger-transport modes, transport-product characteristics of rapidity, economy, convenience, safety, comfort are selected to distinguish passenger-transport products. The principle of vague sets and interval analysis is introduced into transforming the substitutability between passenger transport modes to vague value according to cost type and benefit type product characteristics, after the data of different passenger-product characteristics are obtained. Vague value is transformed to substitute degree by multi-factor transformation. Substitute degree consists of three parts that is the degree of substitutability, degree of non-substitutability and degree of uncertainty.4. The essential of the trip structure configuration of regional integrated transportation corridor is a decision problem, the indexes of which include economic benefit, financial benefit, sustainable development and system optimum. In order to express experts' evaluation information well and truly, triangular fuzzy number is introduced into MADM in this research. Entries in decision matrix and weights of all attributes are represented by triangular fuzzy number. Decision matrix and weight vector of criterions are formed on triangular fuzzy number after evaluation values and weight of criterions are pooled and integrated under condition of group decision-making. And then, two methods are used to rank the alternatives. one is introducing TOPSIS into this paper after a vertex method is proposed to calculate the distance between two triangular fuzzy numbers, According to the concept of the TOPSIS, a closeness coefficient is defined to determine the ranking order of all alternatives by calculating the distances to both the fuzzy positive-ideal solution (FPIS) and fuzzy negative-ideal solution (FNIS) simultaneously. Finally, the order of alternatives is achieved in the light of closeness coefficient. The other is, after the final evaluation value of each alterative is achieved by means of simple additive weighting method (SAW), the degree of dominance between alternatives is defined by the way of difference of two triangular fuzzy numbers. The complementary judgment matrix is built up on degree of dominance between alternatives. The ordering vector of alternatives is figured out though using the least-square method. The order of alternatives is gained according to the value of element of the order vector.5. To diagnose the passenger system of regional comprehensive transoportion corridor, understand its realistic running state and to assess the effect of decision-making, this paper defined the diversity of transportation products, banlance coefficient of supply and demand and OD balance coefficient to evaluate rationality of the trip structure from the angle of internal trip structure of regional comprehensive transoportion corridor. Meanwhile, three indexes, comprehensive supply capacity coefficient, the level of sustainable development and comprehensive transportation efficiency are built to evaluate the trip structure from the angle of adaptability between corridor and social economy. Fuzzy recognition is introduced to evaluation trip structure of regional comprehensive transoportion corridor after evaluation criterion made by membership degree.6. Regional comprehensive corridor takes on the characteristics of heavy transport demand and supply and many travel modes; meanwhile, competition is severe among different travel modes. In order to avoid vicious competition among different travel modes so that transportation market is disturbed, multi-objective and nonlinear programming model is built up, which is based on the maximization of unity of traveler. The objective of model is mutual adaptation of transport demand volume and supply volume. Multi-objective is transferred into single objective by multi-objective fuzzy programming method. At the same time Newton arithmetic is employed to solve nonlinear problem. For the sake of avoiding obtaining local optimal solution, different and stochastic original solutions are adopted to find the local optimal solution, the optimal of which is took as the global optimal solution. The solution is improved to a large extent by this way.From what has been discussed above, the analysis of passenger system of regional comprehensive transportation corridor includes the analysis of trip behavior, the configuration of trip structure, the evaluation of trip structure and the coordination of trip structure in later stage. This paper has done a thorough research on these problems and offered theoretical foundations for optimization, programming and adjustment of regional comprehensive transportation corridor.
