Abstract


Decision-making of the choice of the type of urban rail transit system, play a crucial role in the function of the system to locate and target service, improve operational efficiency and operational benefits, saving the project cost and the consumption of resources and energy, and promote the healthy and rapid development of China's urban rail transit. However, at this stage, because there is no scientific, systematic system type selection decision theory for guidance, is likely to cause the line functions and passenger service objectives are not clear, the transport capacity and traffic not suited, suited to the level of service and passenger demand problem. Therefore, from the perspective of service requirements and functional planning of urban rail transit system, and how to choose the functional orientation reasonable level of service to match the system type of research has important practical significance. In this paper, the development status of China's urban rail transport, and analysis of the situation and characteristics of the foundation of our city, and system type selection theory and method to carry out an exploratory study. The study expects to draw a systematic selection decision theory and method of urban rail transit system, clear characteristics in different cities, different traffic demand under the conditions of each line in the network and the network of urban rail transit planning line should be functional orientation, level of service and performance standards, and select the system type corresponding to adapt to meet the requirements of urban development and urban transport planning line network transport services functional goals, the reasonable control of the construction standards, the scale of construction and engineering investment in secondary cities urban rail transit planning decisions, and provide the basis for the the national management decision-making department's decision-making management, protection of the sustainable development of urban rail transit. This article is mainly carried out research in the following aspects. 1. Hierarchical relationship of urban rail transit Selection Decision. The studies suggest that the overall urban planning, urban natural geographic features, the size of the urban population, urban spatial structure and land use, city residents' travel habits, and other issues related to urban transport characteristics is a prerequisite for urban rail transit network planning and selection decisions. The network planning based on urban basic characteristics of urban transportation needs, urban rail transit system functional requirements selection problem is decomposed into track traffic patterns on the macro-level, the vehicles standard on the system type and micro-level intermediate level three level. 2. Research the type of rail transport mode - system - vehicle standard the three Selection theoretical system. Selection hierarchical division of urban rail transit network planning stage selection of work-based objectives, content, proposed the three Selection of the type of rail transport mode - system - vehicle standard theoretical system, respectively, at the macro, intermediate, microscopic level functions to improve efficiency and resource conservation perspective rail transportation mode, system type, the selection of vehicles standard were superior, the median selection decision, the next bit. Analysis of the basic concepts of the theory of three selection core philosophy, affiliation, selection optimization model of urban rail transit. Study of discrimination based on system type selection: classification of types of system characteristics and applicable conditions. From the functional performance, range of applications, the technical features of the system type is divided into subway systems, light rail system, the City Express Line system and suburban railway system, the tram system and a special dedicated system (including cable rail traffic, AGT low Yun amount of system) types, the researchers analyzed the advantages and disadvantages of various system types, technical features, the applicable conditions and trends, and so, as a follow-up system type selection discriminant basis. 4 selection method based on the system type of rail transport mode (logic reasoning methods). Determine the size of the urban population, urban geography and spatial structure characteristics, characteristics of urban traffic, urban transport development strategy based track traffic patterns, and then select the system type of philosophy, system type selection method based on the mode of rail transit. With the state of the construction of \5. System type of multi-factor multi-program decision-making model (decision-making method). The study proposed the analytic hierarchy process - entropy - gray relational decision model. In the case of the known line some of the features, performance requirements and other quantitative indicators data, provide a combination of a qualitative and quantitative multi-factor comprehensive decision-making method can take full advantage of the white information and expert advisory role to assist in a more accurate system Type selection decisions. 6. Introduced discriminant analysis aided analysis system type selection (cluster analysis method). Subway system, for example, the introduction of distance discriminant analysis method, system type selection application experience, both cities assisted analysis of the city's system type selection decisions; stepwise discriminant analysis, analysis of the impact of the system type selected urban infrastructure data indicators important Weights, pointed out that the Urban GDP, urban fiscal disposable income, the total population of the urban area, the conventional urban bus passenger total urban built area \Indicators and standards of subway construction project approval to the proposed changes. 7 to carry out a case study. Term planning of Shanghai Rail Transit Line network system type selection and the southern section of Line 11 system type selection, for example, the application system type selection method proposed in this article, use the sample. The case studies show that the proposed system type selection theory and methods, correctly guide our city related decision-making system type selection.
