【摘要】：行人交通作为交通枢纽内交通的主要组成部分,越来越受到城市交通研究者、管理者以及交通参与者的重视。由于行人交通行为的多样性、慢速性、随机性、自组织性的特征使得研究行人交通的难度较大,采用传统的解析模型的方法对行人行为特征进行描述更是十分困难。而通过计算机建模进行微观仿真,由于其计算功能的强大和描述行人行为方法的多样,使得其成为当今社会研究、评价行人交通的重要手段。目前,国内对于行人交通仿真研究成果已有一定规模,但多为宏观和中观层次的研究,微观层次的研究较少。本研究正是着眼于建立一个行人交通微观仿真平台,用于研究、评价行人交通及轨道交通枢纽内设施。本文分别对Agent技术和元胞自动机仿真模型的的优势进行了分析,总结其高度的可结合性,挖掘其可操作性,再结合常规的交通仿真研究方法,整理出一套行之有效的建模方法。再以此为基础,建立结合了Agent思想和元胞自动机模型构建而成的行人行为微观仿真模型,以元胞自动机的行为机制为总体框架,以Agent技术为行为个体赋予行为模式。最终在NetLogo平台上建立仿真程序,实现枢纽内行人行为的仿真模拟。本文还通过对北京地铁几个有特点的枢纽车站进行了现场调研,对站内的各类行人设施,如安检机、检票闸机、通道、自动扶梯和站台空间的客流数据进行了收集、统计和分析。为今后轨道交通交通枢纽内设施的新建和改造提供依据和建议。最后,本文对基于Agent和元胞自动机构建而成的行人微观仿真模型进行了可视化实现,并通过仿真结果与实际调研数据的对比分析,证明该仿真建模方法的可行性、有效性和准确性,具有进一步深入研究和推广应用的价值。
[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.
