【摘要】：列车开行起讫点是列车开行方案优化研究的重要要素之一,如何合理的设计对开行方案后期的编制有着重要的影响,在分级分层起讫点优化过程中,由于客流OD数量多使得列车OD的设置可选方案很多。如何明确影响因素,在优化前期对列车OD进行预处理,减少列车OD的组合方案成为了研究的重点和难点。优化前期的预处理工作中,对客运节点进行重要度分析是非常有必要的。国外在高速铁路客运产品规划和设计理念方面形成了丰富的积累,可作为我国铁路客运产品规划的参考,但由于国情和路情的差异,需根据具体情况进行有选择吸收。国内对相关技术点的研究成果,可作为研究的借鉴。本文在分析国内外研究现状的基础上,通过分析节点重要度的影响因素,特别是城市内部车站节点重要度的影响因素,并设计出适合研究问题的评价方法,针对我国快速客运网络节点重要度进行分析计算。研究内容主要包括以下几点： (1)分析了影响客运节点重要度的因素,不仅从节点客流量、路网结构、客运节点技术作业条件、政治经济影响因素进行分析,还引入了在铁路节点重要度分析中,较少应用的图论方法。不仅计算车站衔接边的数量,同时通过设计数学模型优化得到车站衔接边的开行频率值,通过开行频率值来界定边的重要度,再结合车站所在城市节点等级,综合得到车站的节点重要度。 (2)综合了既有针对节点重要度的研究方法,主要包括以主成分分析法、层次分析法和聚类分析法为代表的综合指标评级方法,以及图论中定点的度的计算方法,本文还设计了运输网络中边的重要度计算模型。 (3)以2015年铁路快速客运网络为实例,分别计算了城市级节点重要度和车站级的节点重要度。本文的研究结论,体现了高速铁路的快速、高效等特点,集中化、高密度的列车开行模式,不仅可以降低维修养护基地建设费用,还可以为我国高速铁路周期模式的列车开行方案编制提供条件,提高高速列车服务水平。
[Abstract]:The starting and ending point of train operation is one of the important elements in the optimization study of train operation plan. How to design reasonably has an important influence on the establishment of the later stage of the train operation plan. Due to the large number of OD in passenger flow, there are many options for setting up OD. How to make clear the influencing factors and preprocess the OD of train in the early stage of optimization, Reducing the combination of train OD has become the focus and difficulty of the research. In the pre-optimization of pre-processing, it is very necessary to analyze the importance of passenger nodes. Foreign countries have formed a rich accumulation in high-speed railway passenger transport product planning and design concept, which can be used as a reference for China's railway passenger transport product planning, but due to the differences in national conditions and road conditions, The domestic research results of relevant technical points can be used for reference. Based on the analysis of the current research situation at home and abroad, this paper analyzes the influencing factors of node importance, especially the influence factors of urban station node importance, and designs an evaluation method suitable for the study of the problem. Based on the analysis and calculation of the node importance of the rapid passenger transport network in China, the main contents of the research include the following:. This paper analyzes the factors that affect the importance of passenger transport node, not only from the aspects of node passenger flow, network structure, technical operating conditions of passenger transport node, political and economic influence factors, but also the analysis of importance degree of railway node. The less applied graph theory method is not only to calculate the number of the connecting edges of the station, but also to optimize the opening frequency of the connecting edge of the station by designing a mathematical model, and to define the importance of the edge by the value of the frequency of the opening line. Combined with the city node grade of the station, the node importance degree of the station is obtained. 2) synthesizing the existing research methods for node importance, including the comprehensive index rating method represented by principal component analysis, analytic hierarchy process and cluster analysis, as well as the calculation method of the degree of fixed point in graph theory. This paper also designs the calculation model of edge importance in transportation network. Taking 2015 railway rapid passenger transport network as an example, the importance degree of urban node and station level is calculated respectively. The conclusion of this paper reflects the characteristics of high speed railway, such as high speed and high efficiency. The centralized and high density train running mode can not only reduce the construction cost of maintenance and maintenance base. It can also provide the conditions for the train operation scheme of the cycle mode of high-speed railway in China, and improve the service level of the high-speed train.
