【摘要】：行人群體仿真在結(jié)構(gòu)設(shè)計、安全科學、行人交通、社會科學、娛樂產(chǎn)業(yè)等領(lǐng)域都有廣泛研究。目前已經(jīng)產(chǎn)生了幾種行人群體行為的微觀仿真模型,但人群活動的重要特性仍然需要進步研究。現(xiàn)有行人仿真研究往往關(guān)注于行人群體緊急情況下而不是平常情況下行人群體行為,主要研究了個體行人的行為而沒有重視人群中存在大量中觀的社會小群體(Social Group,統(tǒng)稱同伴群),如朋友、夫妻等,高密度和低密度行人需要分別進行不同的模型和參數(shù)標定而不是進行統(tǒng)一的運動建模。平常情況下同伴群的群體動力學、其比例和規(guī)模對行人流的影響以及不同人流密度中的形態(tài)特性和活動特性研究還不充分。本文對此進行同佯群行人活動特性分析、模型和仿真平臺構(gòu)建、行人場景仿真三個方面的研究。本文首先從行人微觀仿真模型、同伴群及行人異質(zhì)化三個方面對研究問題進行綜述；其次進行視頻數(shù)據(jù)采集并對行人活動特性進行分析,研究了行人基本活動參數(shù)和同伴群活動規(guī)律；接著進行行人仿真建模方法的分析,并在Agent方法、仿真驅(qū)動模型基礎(chǔ)上初步提出本文的社會力學模型理論框架；然后在分析社會力學特點和不足后,結(jié)合構(gòu)建的Agent理論框架進行行人同伴群社會力學模型改進和實現(xiàn)。并在改進模型基礎(chǔ)上使用面向?qū)ο缶幊碳夹g(shù)實現(xiàn)行人仿真平臺；最后針對行人仿真的同伴群群體特性、形態(tài)特征、群體動力學及對人群動力學影響等進行仿真研究。
[Abstract]:Pedestrian group simulation has been widely studied in the fields of structure design, safety science, pedestrian traffic, social science, entertainment industry and so on. However, the important characteristics of crowd activity still need to be further studied. Existing pedestrian simulation studies tend to focus on pedestrian crowd behavior in emergencies rather than in ordinary situations. This paper mainly studies the behavior of individual pedestrian without paying attention to the social group with a large number of meso social groups in the crowd, which is called peer group, such as friends, husband and wife, etc. High density and low density pedestrians need different models and parameters calibration instead of unified motion modeling. The effect of the proportion and scale on the pedestrian flow and the study of the morphological and activity characteristics of the pedestrian flow in different density are not enough. This paper analyzes the pedestrian movement characteristics of the same group, builds the model and the simulation platform. Three aspects of pedestrian scene simulation research. Firstly, this paper summarizes the research problems from three aspects: pedestrian microscopic simulation model, peer group and pedestrian heterogeneity. Secondly, video data acquisition and pedestrian activity characteristics are analyzed. The basic parameters of pedestrian activity and the law of peer group activity are studied, then the pedestrian simulation modeling method is analyzed, and based on the Agent method and simulation driven model, the theoretical framework of this paper's social mechanics model is put forward preliminarily. Then, after analyzing the characteristics and shortcomings of social mechanics, the pedestrian peer group social mechanics model is improved and implemented based on the constructed Agent framework. Based on the improved model, the pedestrian simulation platform is realized by using object-oriented programming technology. Finally, the characteristics of peer group, morphological characteristics, group dynamics and the effect on crowd dynamics of pedestrian simulation are simulated.
