【摘要】：摘要：随着社会经济快速发展,城市化进程不断加快,人们出行方式呈现多元化,行人可选择多种交通方式出行,但是绝大多数出行的开始与结束都是以步行完成。步行交通在各种交通方式中有其不可替代的作用,同时步行交通也引发了多类新的交通问题。许多公共场所如车站、行人通道、过街天桥、交通枢纽等处行人拥堵现象屡见不鲜,导致行人出行不便,出行延误较长,出行安全性降低。由此,国内外相关机构、单位及个人均纷纷开展行人交通特性的研究,以期掌握行人交通的宏观及微观特征,了解行人行为机理,对行人交通进行规划管理,提升行人交通效率,增强安全性以及减小行人对其他交通方式的影响。本文在综述行人交通研究现状的基础上,对于同伴群行人交通进行研究,以求进一步丰富和完善行人交通流的研究体系。同时,在分析研究的基础上,建立基于社会力的同伴群走行模型。该模型在2002年Helbing社会力模型的基础上,补充考虑同伴群成员间的视觉力、聚合力及排斥力,进而利用计算机仿真技术,研究同伴群行人的特性及对交通的影响。本文对下列几个问题进行分析研究： (1)行人交通特性分析研究分析行人交通微观、宏观特性,研究了行人交通流参数及各参数之间的关系,以及同伴群行人的交通特性。 (2)基于社会力的同伴群走行模型构建及应用对社会力模型的定义、构成、特征进行分析,从而把握社会力模型机理。基于对同伴群行人交通特性的研究总结,定义同伴群走行模型,借助MATLAB,实现基于社会力模型的仿真环境开发,对同伴群行人交通进行仿真研究。 (3)同伴群行人对整体交通流宏观特性的影响借助MATLAB开发的基于社会力模型的仿真环境,对是否考虑同伴群出行及对行人群体含有不同比例同伴群,同伴群内含不同人员数等情景进行仿真分析,由此得出同伴群行人较个体行人,影响交通流速度更大的结论,为更全面分析行人交通流提供了更好的支持。
[Abstract]:Absrtact: with the rapid development of social economy and the accelerating process of urbanization, people travel in a variety of ways, pedestrians can choose a variety of traffic modes to travel, but most of the trips start and end on foot. Walking traffic plays an irreplaceable role in various modes of transportation, and at the same time, it also causes many kinds of new traffic problems. In many public places, such as stations, pedestrian passageways, overpasses and traffic hubs, pedestrian congestion is common, which leads to the inconvenience of pedestrian travel, long travel delay and reduced travel safety. As a result, relevant institutions, units and individuals at home and abroad have carried out research on pedestrian traffic characteristics in order to grasp the macro and micro characteristics of pedestrian traffic, understand the pedestrian behavior mechanism, and plan and manage pedestrian traffic. Improve pedestrian traffic efficiency, enhance safety and reduce pedestrian impact on other modes of traffic. On the basis of summarizing the present situation of pedestrian traffic research, this paper studies the pedestrian traffic of peer group in order to further enrich and perfect the research system of pedestrian traffic flow. At the same time, on the basis of analysis and research, a peer group walking model based on social force is established. Based on the Helbing social force model in 2002, this model takes into account the visual force, cohesion and repulsive force among peer group members, and then uses computer simulation technology to study the characteristics of peer group pedestrians and their effects on traffic. This paper analyzes the following problems: Analysis of pedestrian traffic characteristics The microscopic and macroscopic characteristics of pedestrian traffic are analyzed, and the relationship between pedestrian flow parameters and various parameters, as well as the traffic characteristics of peer groups of pedestrians are studied. Construction and Application of Peer Group Walking Model based on Social Force The definition, composition and characteristics of social force model are analyzed to grasp the mechanism of social force model. Based on the summary of the research on the pedestrian traffic characteristics of peer group, the peer group walking model is defined, and the simulation environment based on social force model is developed by MATLAB to simulate the pedestrian traffic of peer group. 3) the influence of peer group pedestrians on the macroscopic characteristics of overall traffic flow With the help of the simulation environment based on social force model developed by MATLAB, the simulation analysis of whether to consider peer group travel and to have different proportion of peer group to pedestrian group and different number of people in peer group are carried out. The conclusion that the pedestrian of peer group has more influence on the speed of traffic flow than that of individual pedestrian provides a better support for a more comprehensive analysis of pedestrian traffic flow.
