【摘要】：近年来,城市轨道交通作为城市交通的骨干运输系统,在我国的多个大中型城市得到了快速的发展。纵观国内外城市,网络化运营已经成为城市轨道交通建设与发展的必然趋势,路网规模在不断的扩大,路网结构在进一步的完善。但是,由于自然灾害、设备故障、运营管理等多个方面的因素,城市轨道交通系统不可避免的会发生突发的中断事故,给城市的交通系统带来经济损失,并且损害到乘客的出行乃至生命财产安全。因此,研究突发中断下城市轨道交通的应急客流疏运的相关问题具有着极其重要的理论和现实意义。论文以“突发中断情况下轨道交通的应急客流疏运”作为研究对象,从突发中断事件以及轨道交通列车运营调整方法入手,以轨道交通路网的连通可靠性仿真作为研究基础,结合城市轨道交通行车组织的相关理论及方法,从客流分析、折返站设置、客流疏散、应急体系、应急公交联动等多方面开展了较为深入的研究,主要的研究内容如下： (1)从事故原因、影响等级等方面归纳介绍了城市轨道交通的突发中断事件,并且总结了其所呈现主要特点,进而系统的汇总和归纳了现有的、常见的突发中断事件中轨道交通列车的应急调整方法。 (2)引入图论以及复杂网络中相关的概念及理论,建立了成都市地铁规划路网的网络拓扑结构模型,以节点的度数、网络的平均连接效率、节点的网络凝聚度等参数作为标准,仿真研究了成都市路网在随机性突发中断以及选择性突发中断条件下的连通可靠性,并进一步仿真研究了路网中不同的节点对于路网整体的连通可靠性以及结构稳定性所起到的不同作用。 (3)根据仿真的研究结果,深入分析了随机性突发中断条件下的路网的客流特点,在此基础上建立了此种情况下的客流疏散的最优径路集生成模型,设计了Dijkstra算法和改进的删除算法相结合的求解算法,并结合相关的算例和数据,进行了编程求解。 (4)以仿真结果为基础,从应急体系、应急预案以及城市公共交通的应急联动等方面研究了轨道交通系统在选择性突发中断条件下轨道交通客流疏运的应急策略问题。
[Abstract]:In recent years, as the backbone transportation system of urban transportation, urban rail transit has been developing rapidly in many large and medium-sized cities in China. Network operation has become an inevitable trend in the construction and development of urban rail transit. The scale of the network is constantly expanding, and the network structure is being further improved. However, due to natural disasters, equipment failures, operation management and other factors, The urban rail transit system will inevitably have a sudden interruption accident, which will bring economic losses to the urban transportation system, and damage the travel of passengers and even the safety of life and property. It is of great theoretical and practical significance to study the problems related to the emergency passenger flow of urban rail transit under sudden interruption. In this paper, the emergency passenger flow of rail transit under the condition of sudden interruption is taken as the research object, starting with the sudden interruption and the adjustment method of rail transit train operation, and taking the connected reliability simulation of rail transit network as the research foundation. Combined with the related theories and methods of urban rail transit traffic organization, this paper has carried out more in-depth research from many aspects, such as passenger flow analysis, reentry station setting, passenger flow evacuation, emergency system, emergency bus linkage and so on. The main research contents are as follows:. 1) the sudden interruption of urban rail transit is introduced from the aspects of accident cause, influence grade and so on, and the main features are summarized, and then the existing ones are summarized systematically. The common emergency adjustment method of rail transit train in sudden interruptions. 2) by introducing graph theory and related concepts and theories in complex networks, a network topology model of metro network planning in Chengdu is established. The parameters such as the degree of nodes, the average connection efficiency of networks and the network cohesion of nodes are taken as the standard. The connectivity reliability of Chengdu road network under the condition of random burst interruption and selective burst interruption is studied by simulation. Furthermore, the effects of different nodes on the overall connectivity reliability and structural stability of the road network are studied by simulation. 3) based on the results of simulation, the characteristics of road network passenger flow under the condition of random sudden interruption are deeply analyzed, and the optimal path set generation model of passenger flow evacuation under this condition is established. The Dijkstra algorithm combined with the improved deletion algorithm is designed, and the solution is programmed by combining the relevant examples and data. 4) based on the simulation results, this paper studies the emergency strategy of the rail transit system under the condition of selective sudden interruption from the aspects of emergency system, emergency plan and emergency linkage of urban public transportation.
