【摘要】：步行作为其他几种出行方式的重要衔接部分,其在所有出行方式中扮演着极其重要的角色。近年来,国家性或者区域性的大型活动每年都会如期举行,这些活动在带来经济效益和社会效益的同时也隐藏着巨大的安全隐患。本文的研究目的就是在行人踩踏安全事故频发的背景下,基于步行空间中的独立行走个体和结伴出行的同伴群成员群表现出来的差异性行为,建立一种既能够体现单个行人个体,又能够刻画结伴出行行人行为的动力学运动方程,研究特定步行空间里行人的运动行为,为步行空间的合理规划设计及优化评估提供参考。本文主要从以下几个方面开展了研究：首先,本文从行人行为微观建模与计算机仿真、行人同伴群群集行为及行人异质化研究、行人运动行为等三个方面对已有的行人交通行为研究问题进行综述,归纳总结了现有行人交通基本仿真模型的优缺点、运用范围,对比分析了现有基于原始模型开发的仿真软件的优缺点。其次,基于上述分析选取了社会力学模型作为本文行为建模的基础研究模型,并详细介绍了社会力模型的基本原理,根据真实的行人行为分析了模型的不足,并在此基础上,加入了一些新的规则,比如,双向行人流中行人的动态避让行为及差异化行人的路径规划,对算法进行了改进优化,使得模型能够更加真实地模拟行人行为。最后,本文以VC++及QT作为开发工具,以建立的行人动力学模型为基础,开发了行人个体及同伴群模拟平台,并利用该平台进行了人群运动仿真,根据仿真得到的行为演示以及仿真数据对比分析了改进模型与原始模型的优缺点,此外利用该平台对大规模行人聚集区进行了仿真研究,较为形象地展现了人群聚集区行人流的动态演变规律,最后在该平台上重现了Helbing社会力模型的若干经典现象。
[Abstract]:Walking as several other important part of travel mode, which plays a very important role in all the way to travel. In recent years, the national or regional events each year will be held as scheduled, these activities also hiding a huge security risks in the economic benefits and social benefits at the same time. The purpose of this study is in frequent accidents trampled under the background of the behavior difference of walking space in independent walking and individual travel together peer group members of the group show based on the establishment of a single individual can not only reflect the pedestrian, and can describe the dynamics equation of motion travel with pedestrian behavior, study specific pedestrian space of pedestrians in motion behavior, provide a reference for the design and optimization of reasonable planning and assessment of walking space. This paper mainly from the following aspects: first, this research carried out This paper from the microscopic modeling and computer simulation of pedestrian pedestrian behavior, peer groups in behavior and pedestrian heterogeneity research, summarizes the pedestrian traffic behavior research on the existing problems of the three aspects of pedestrian movement behaviors, summarizes the existing pedestrian traffic simulation model of the advantages and disadvantages, application scope, comparative analysis of the advantages and disadvantages of the existing simulation software development the original model based on the above analysis. Secondly, the selection of the social mechanics model as the basis of this study model based on behavior modeling, and introduces the basic principle of the social force model, according to the analysis of real pedestrian behavior model, and on this basis, adding some new rules, for example, path planning pedestrian avoidance behavior and dynamic difference of the bidirectional flow of pedestrians, the improved algorithm optimization, the model can realistically simulate the pedestrian Behavior. Finally, this paper takes VC++ and QT as the development tool, the pedestrian dynamics model is established for the foundation, developed individual and peer group pedestrian simulation platform, and the crowd movement simulation by using this platform, according to the simulation results of the behavior simulation data demonstration and comparative analysis of advantages and disadvantages of the improved model and the original model, in addition use the platform for large-scale pedestrian gathering area is simulated, more vividly demonstrated the dynamic population gathering area for pedestrian evolution, finally on the platform to reproduce the social force model of Helbing the classic phenomenon.
