【摘要】 当前,国内各大中型城市地面交通拥堵已成为亟待解决的问题,城市轨道交通因为其所具备的大容量运输能力、相对独立性、高速度运营、安全舒适等特点成为了城市交通的大动脉。随着国民经济的发展,城市内部的交流活动愈加频繁,活动前客流的聚集以及活动结束后客流的疏散都极易引发大客流事件,此时城市轨道交通将面对巨大的客流疏散压力。另外,城市轨道交通线路并网运营已是大势所趋,此时大客流的疏散将由简单独立的单线变为复杂的网络疏散。本文通过分析大客流在城市轨道交通路网中的传播特性,研究了城市轨道交通网络遭遇大客流时可以采取的应急控制策略。本文研究了城市轨道交通网络大客流的形成过程和识别方法,通过对城轨网络拓扑和结构特性的分析,研究了复杂网络理论分析城市轨道交通网络的可行性。以车站微观层面为单位,研究了突发大客流在起始站、中间站、换乘站这三类站点内的传播与衰减过程,计算了列车的延误以及运能的变化。对大客流发生时的应急控制策略进行了研究,本文从列车运输组织优化和车站客流控制两方面对大客流在城市轨道交通网络中的传播进行管理和控制。建立SIRS大客流传播模型,以重庆轨道交通网络为例,使用MATLAB对大客流发生后城市轨道交通网络中拥挤车站的比例进行仿真演化,得到网络中拥挤站点的变化情况,并以此为依据对应急管理控制策略的有效性进行了分析。更多还原

【Abstract】 Nowadays the ground traffic congestion has became one of the most important questions which need to be solved for many cities,because of the highly transport capacity、the relative independence、the high speed、the safety and the comfortable characteristics,the urban rail transit has became the aortic in city.Developing with the economic,the activity in city also growing,it is easy to initiation sudden accident and the urban rail transit system bear huge pressure.Otherwise the operation of urban rail road is tend to networks,the dissipate of large passenger flow will be more complex.This article analysis the spread characteristic of large passenger flow and the emergency organization in urban rail transit.This article analysis the process of large passenger flow and put forward the method to distinguish different flows,through the structure research of network and topology,the complex network theory is proved to be useful in transit network analysis,through the station of urban rail transit analysis the spread and dissipate process in different stations and compute the changes of transportation ability and the delays of the trains.Research the emergency organization of large passenger flow,this article through the rail organization and the passengers control in station to control the spread of passengers flow in networks.Establish the passengers spread model SIRS and take Chongqing rail transit as an example to research the spread process,analysis the effectiveness of emergency organization with the changes of crowd stations.更多还原
