【摘要】：近年来,随着城市进程的不断发展和人们物质文化生活水平的不断提高,越来越多的大型活动在各大城市竞相举办。当然,大型活动的举办引发的大量出行人员尤其是大型活动散场时,大量的人员和车辆会对城市日常交通设施造成巨大的交通压力,可能会使路网造成拥堵。短时间内增加公路交通设施不太可能,而且大型活动过后会造成资源的浪费,因此,如何组织交通疏散活动,安全、有效、快速地将人员和车辆进行疏散是一个非常值得研究的课题。本文分别站在交通组织管理者和交通出行者的角度研究了大型活动交通疏散问题的交通流分配和出行者的路径选择,本文重点的研究内容包括如下几个方面。首先,进行了国内外大型活动的研究综述,分别从交通出行者路径选择的微观角度和交通组织管理者交通流规划的宏观角度两个方面进行,还介绍了仿真系统在大型活动交通疏散问题研究中的应用。其次,分析了大型活动交通疏散的需求特征和组织管理特征,结合交通流分配理论,建立起大型活动交通疏散的静态数学模型。针对模型特征,选择了LINGO和ILOG软件求解,并以沈阳奥体中心举办十二运为背景进行实际案例分析。再次,进行了基于仿真软件Arena的大型活动不同场景下交通疏散的动态仿真研究。定义了不同的实体对象,设计了相应的逻辑模型,以沈阳奥体中心举办十二运为背景,模拟大型活动散场疏散过程的具体实现,建立仿真动画。在前面模型的基础上,嵌入VB模块,针对道路上交通量发生变化时,对模型参数进行修改,对大型活动交通疏散进行动态的仿真。最后,将全文对大型活动交通疏散问题的研究进行总结,并指出研究的不足之处,对未来的研究方向做出展望。
[Abstract]:In recent years, with the continuous development of the urban process and the continuous improvement of people's material and cultural living standards, more and more large-scale activities are held in the major cities. Of course. The large number of people travelling, especially when the event is over, will cause great traffic pressure on the daily traffic facilities of the city. It is unlikely to increase road traffic facilities in a short period of time and waste resources after large-scale activities. Therefore, how to organize traffic evacuation activities, safe and effective. It is worth studying how to evacuate people and vehicles quickly. In this paper, traffic flow distribution and travel of large-scale activities are studied from the point of view of traffic organization manager and traffic traveler, respectively. The choice of path. This paper focuses on the following aspects. First of all, the domestic and foreign large-scale activities are reviewed. It is carried out from two aspects: the microscopic angle of route choice and the macroscopic angle of traffic flow planning of traffic organization manager. The paper also introduces the application of simulation system in the study of traffic evacuation of large-scale events. Secondly, it analyzes the demand characteristics and organizational management characteristics of traffic evacuation for large-scale events, and combines the theory of traffic flow allocation. The static mathematical model of large-scale traffic evacuation is established. According to the characteristics of the model, LINGO and ILOG software are chosen to solve the problem. And to Shenyang Olympic Sports Center held 12 for the background of the actual case study. Again. Based on the simulation software Arena, the dynamic simulation of traffic evacuation in different scenes of large-scale events is studied. Different entity objects are defined and the corresponding logical model is designed. Based on the background of the 12 Olympic Games in Shenyang Olympic Sports Center, this paper simulates the concrete realization of the evacuation process of large-scale events, and establishes the simulation animation. On the basis of the previous model, VB module is embedded. According to the change of traffic volume on the road, the model parameters are modified, and the dynamic simulation of large-scale activity traffic evacuation is carried out. Finally, the paper summarizes the research of large-scale activity traffic evacuation problem. And pointed out the shortcomings of the study, and the future direction of research.
