【摘要】：步行作為其他幾種出行方式的重要銜接部分,其在所有出行方式中扮演著極其重要的角色。近年來,國家性或者區(qū)域性的大型活動每年都會如期舉行,這些活動在帶來經(jīng)濟效益和社會效益的同時也隱藏著巨大的安全隱患。本文的研究目的就是在行人踩踏安全事故頻發(fā)的背景下,基于步行空間中的獨立行走個體和結(jié)伴出行的同伴群成員群表現(xiàn)出來的差異性行為,建立一種既能夠體現(xiàn)單個行人個體,又能夠刻畫結(jié)伴出行行人行為的動力學(xué)運動方程,研究特定步行空間里行人的運動行為,為步行空間的合理規(guī)劃設(shè)計及優(yōu)化評估提供參考。本文主要從以下幾個方面開展了研究：首先,本文從行人行為微觀建模與計算機仿真、行人同伴群群集行為及行人異質(zhì)化研究、行人運動行為等三個方面對已有的行人交通行為研究問題進行綜述,歸納總結(jié)了現(xiàn)有行人交通基本仿真模型的優(yōu)缺點、運用范圍,對比分析了現(xiàn)有基于原始模型開發(fā)的仿真軟件的優(yōu)缺點。其次,基于上述分析選取了社會力學(xué)模型作為本文行為建模的基礎(chǔ)研究模型,并詳細介紹了社會力模型的基本原理,根據(jù)真實的行人行為分析了模型的不足,并在此基礎(chǔ)上,加入了一些新的規(guī)則,比如,雙向行人流中行人的動態(tài)避讓行為及差異化行人的路徑規(guī)劃,對算法進行了改進優(yōu)化,使得模型能夠更加真實地模擬行人行為。最后,本文以VC++及QT作為開發(fā)工具,以建立的行人動力學(xué)模型為基礎(chǔ),開發(fā)了行人個體及同伴群模擬平臺,并利用該平臺進行了人群運動仿真,根據(jù)仿真得到的行為演示以及仿真數(shù)據(jù)對比分析了改進模型與原始模型的優(yōu)缺點,此外利用該平臺對大規(guī)模行人聚集區(qū)進行了仿真研究,較為形象地展現(xiàn)了人群聚集區(qū)行人流的動態(tài)演變規(guī)律,最后在該平臺上重現(xiàn)了Helbing社會力模型的若干經(jīng)典現(xiàn)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.
