【摘要】：城市轨道交通线路作为城市公共交通网络的主干，其具有运能大、人流密集、信息化程度高、反应迅速、系统封闭等特征。日常运营过程中，，设备故障、自然灾害及其人为等事故的发生不可避免，这些突发事件往往会造成轨道交通网络的局部中断，导致部分车站、区段停运，乘客无法在停运区段正常进、出站。在轨道交通网络突发中断事件发生时，充分利用地面公共交通工具作为轨道交通客流疏运的联动支持方式，实现受影响客流的运输接续，是满足乘客出行需求，保障城市客运交通系统整体运输秩序的有效手段。本文选取机动灵活、部署便捷的公共汽车作为城市轨道交通突发中断事件时客流疏运的联动方式，研究公交联动方案制定的相关问题，主要内容如下： 1.根据突发中断事故对于交通网络整体的影响程度将其分为随机性突发中断和选择性突发中断两种情况，明确论文的研究对象为随机性突发中断情况。结合国内外轨道交通突发中断事故应急相关理论研究文献及实施办法，系统归纳、探讨突发中断事件时轨道交通列车运行调整方案及公交应急联动模式。 2.考虑客流所处的位置与停运区间之间的关系，对受突发中断影响的乘客进行分类，分别确定各类受影响乘客的规模。以受影响乘客为对象，研究其出行选择行为，建立突发中断事件时的出行阻抗函数，构建客流重分配模型，从而确定客流疏运公交联动客流量。 3.提出城市轨道交通突发中断事件应急响应流程、公交应急联动的执行决策流程，进而从客流疏运公交运力提供角度出发，确定客流疏运公交联动的配合策略。运力有限条件下公交联动的配合策略以引导管理为主，运力充足条件下的配合策略为向乘客提供与去向需求更佳贴切的运输替代服务。 4.制定客流疏运公交联动方案，在运力充足的情况下，考虑应急公交最远疏运范围为乘客在停运区间上下游乘坐轨道交通的平均距离，综合考虑应急公交运力、公交运行总车公里，乘客总出行时间、线路满载率等因素，研究制定客流疏运公交联动线路的开行方案。 5.算例分析。假设某城市发生轨道交通网络突发中断事件，造成一条轨道交通线路区间停运，以此为背景进行算例计算，验证本文所建模型和所提出的算法的有效性。
[Abstract]:As the backbone of urban public transport network, urban rail transit lines have the characteristics of large capacity, dense flow of people, high degree of information, rapid response and system closure. In the daily operation process, equipment failures, natural disasters and man-made accidents are inevitable. These emergencies often cause partial disruption of rail transit network, resulting in partial station and section suspension. Passengers are unable to enter and leave the stop normally in the stop-out section. When the sudden interruption of rail transit network occurs, the ground public transport vehicle is fully used as the linkage support mode of the passenger flow of rail transit, and the transportation continuity of the affected passenger flow is realized, which is to meet the travel needs of passengers. The effective means to ensure the overall transportation order of the urban passenger transport system. In this paper, the flexible and convenient bus is chosen as the linkage mode of the passenger flow when the urban rail transit is interrupted, and the related problems of the bus linkage scheme are studied. The main contents are as follows: 1. According to the impact degree of sudden interruption on the whole traffic network, it can be divided into two situations: random sudden interruption and selective sudden interruption, and the research object of this paper is random burst interruption. Combined with the relevant theories and implementation methods of rail transit sudden interruption accident at home and abroad, this paper systematically summarizes the train operation adjustment scheme and bus emergency linkage mode in the event of sudden interruption. 2. Considering the relationship between the location of the passenger flow and the stop interval, the passengers affected by the sudden interruption are classified, and the size of the affected passengers is determined respectively. Taking the affected passengers as the object, the travel choice behavior of the affected passengers is studied, and the travel impedance function is established for the sudden interruption event, and the passenger flow redistribution model is constructed, so as to determine the passenger flow of the public transport linkage. 3. This paper puts forward the emergency response flow of urban rail transit sudden interruption event and the executive decision-making process of bus emergency linkage, and then from the point of view of public transport capacity, determines the coordination strategy of public transportation linkage between passenger flow and public transportation. Under the condition of limited transportation capacity, the coordination strategy of bus linkage is mainly guided management, and the coordination strategy under sufficient capacity is to provide passengers with a better alternative service to meet the needs of destination. 4. In the case of sufficient transportation capacity, considering the farthest distance of emergency public transportation is the average distance between the upper and lower reaches of rail transit, and considering the capacity of emergency public transportation. This paper studies and formulates the operation plan of the passenger transport linkage line by the factors such as total bus kilometers total passenger travel time and full load rate of the line. 5. Example analysis. Suppose an urban rail transit network is interrupted suddenly resulting in a rail transit line interval outage as the background of a calculation example to verify the effectiveness of the proposed model and the proposed algorithm.
