【摘要】：行人交通作為交通樞紐內(nèi)交通的主要組成部分,越來(lái)越受到城市交通研究者、管理者以及交通參與者的重視。由于行人交通行為的多樣性、慢速性、隨機(jī)性、自組織性的特征使得研究行人交通的難度較大,采用傳統(tǒng)的解析模型的方法對(duì)行人行為特征進(jìn)行描述更是十分困難。而通過(guò)計(jì)算機(jī)建模進(jìn)行微觀仿真,由于其計(jì)算功能的強(qiáng)大和描述行人行為方法的多樣,使得其成為當(dāng)今社會(huì)研究、評(píng)價(jià)行人交通的重要手段。目前,國(guó)內(nèi)對(duì)于行人交通仿真研究成果已有一定規(guī)模,但多為宏觀和中觀層次的研究,微觀層次的研究較少。本研究正是著眼于建立一個(gè)行人交通微觀仿真平臺(tái),用于研究、評(píng)價(jià)行人交通及軌道交通樞紐內(nèi)設(shè)施。 本文分別對(duì)Agent技術(shù)和元胞自動(dòng)機(jī)仿真模型的的優(yōu)勢(shì)進(jìn)行了分析,總結(jié)其高度的可結(jié)合性,挖掘其可操作性,再結(jié)合常規(guī)的交通仿真研究方法,整理出一套行之有效的建模方法。再以此為基礎(chǔ),建立結(jié)合了Agent思想和元胞自動(dòng)機(jī)模型構(gòu)建而成的行人行為微觀仿真模型,以元胞自動(dòng)機(jī)的行為機(jī)制為總體框架,以Agent技術(shù)為行為個(gè)體賦予行為模式。最終在NetLogo平臺(tái)上建立仿真程序,實(shí)現(xiàn)樞紐內(nèi)行人行為的仿真模擬。 本文還通過(guò)對(duì)北京地鐵幾個(gè)有特點(diǎn)的樞紐車站進(jìn)行了現(xiàn)場(chǎng)調(diào)研,對(duì)站內(nèi)的各類行人設(shè)施,如安檢機(jī)、檢票閘機(jī)、通道、自動(dòng)扶梯和站臺(tái)空間的客流數(shù)據(jù)進(jìn)行了收集、統(tǒng)計(jì)和分析。為今后軌道交通交通樞紐內(nèi)設(shè)施的新建和改造提供依據(jù)和建議。 最后,本文對(duì)基于Agent和元胞自動(dòng)機(jī)構(gòu)建而成的行人微觀仿真模型進(jìn)行了可視化實(shí)現(xiàn),并通過(guò)仿真結(jié)果與實(shí)際調(diào)研數(shù)據(jù)的對(duì)比分析,證明該仿真建模方法的可行性、有效性和準(zhǔn)確性,具有進(jìn)一步深入研究和推廣應(yīng)用的價(jià)值。
[Abstract]:Pedestrian traffic, as the main component of traffic in traffic hub, has been paid more and more attention by urban traffic researchers, managers and traffic participants. Due to the diversity, slowness and randomness of pedestrian traffic behavior, The characteristics of self-organization make it more difficult to study pedestrian traffic, and it is more difficult to describe pedestrian behavior by traditional analytical model. Because of its powerful computing function and various methods of describing pedestrian behavior, it has become an important means of social research and evaluation of pedestrian traffic. At present, the research results of pedestrian traffic simulation in China have been on a certain scale. However, most of the researches are macro and meso level, but the micro level is less. This study is focused on the establishment of a pedestrian traffic micro simulation platform for the study and evaluation of pedestrian traffic and rail transit hub facilities. This paper analyzes the advantages of Agent technology and cellular automata simulation model, summarizes its high degree of integration, excavates its maneuverability, and combines with conventional traffic simulation research methods. A set of effective modeling methods is put forward. Based on this, a micro-simulation model of pedestrian behavior is established, which combines the idea of Agent and the cellular automata model, and takes the behavior mechanism of cellular automata as the overall framework. Finally, the simulation program is established on the NetLogo platform to realize the simulation of pedestrian behavior in the hub. This paper also carries on the spot investigation to several characteristic hub stations of Beijing subway, and collects the passenger flow data of all kinds of pedestrian facilities in the station, such as security check machine, ticket check gate, passageway, escalator and platform space. Statistics and analysis. Provides the basis and suggestion for the construction and reconstruction of the railway transportation hub facilities in the future. Finally, the simulation model of pedestrian based on Agent and cellular automata is implemented visually, and the feasibility of the simulation modeling method is proved by comparing the simulation results with the actual investigation data. The validity and accuracy have the value of further research and application.
