【摘要】 计算机仿真是目前人们进行科学研究和解决现实中难以实现问题的一种主要方法。交通仿真是计算机仿真技术在交通工程领域的一个重要应用。在交通理论、计算机硬件和软件技术、基础交通设施和社会需求不断发展的推动下,交通仿真研究,尤其是微观交通仿真的研究取得了巨大的发展。 本文以城市道路交通微观仿真建模和相应的仿真软件系统开发为研究重点,全文主要工作如下: 1.在了解和学习国外微观交通仿真研究基础上,对微观交通仿真研究的现状和存在的不足进行了综述性的分析和评价,并建立了微观交通仿真模型体系结构,该模型体系结构由交通需求模型、路网描述模型、控制方案描述模型、车辆行驶模型、交叉口冲突模型、车辆运行轨迹模型、系统评价模型所构成。 2.以宝鸡市4交叉口为例,介绍了干道多信控交叉口协调控制方法,详细的介绍了车辆行驶模型、交叉口冲突处理模型以及系统评价指标。 3.开发了城市微观交通仿真系统,提出了城市微观交通仿真系统软件开发中一些关键技术问题的处理方法。最后,在VC6的开发环境下,运用Opengl开发了微观交通仿真软件系统—UTSS,初步实现了上述模型,为以后开发用于网络交通分析和控制策略评价的大规模微观交通仿真软件打下基础。 最后,总结了全文的工作,并指出了今后进一步研究的问题。更多还原

【Abstract】 At present, the computer simulation is a kind of main method in scientific research and solving the real-life problem difficult to implement. Traffic simulation is an important application of technology of computer simulation in the field of traffic engineering. People began to utilize the computer to imitate the traffic behaviors, the research of traffic simulation, especially the research of microscopic traffic simulation, has made enormous progress, urging by of development of traffic theory, computer hardware and software engineering, basic traffic facility and social demand. Computer hardware and software engineering, especially for software programming and modeling technology, are developed rapidly during recent decades. Its rapid development is playing an essential role to the development of traffic simulation.The main contents and contributions can be summed up as follows:1. The microscopic traffic simulation modeling and the design of the relevant simulation software are the research focus in this paper. On the basis of understanding and studying the domestic and international research of microscopic traffic simulation, summarized the present situation and existing deficiency in the research field of microscopic traffic simulation.2. Build a framework of the microscopic traffic simulation modeling. It constituted by traffic demand model, road network model, vehicle running model, intersection conflict model, vehicle running track model, system evaluation model.Describe the vehicle running model and intersection conflict model on emphasis,including with vehicle-following model and the achievements researched on this model.3. The solving methods of some key technologic problem in the designee of microscopic traffic simulation software were decribed.In the end, the thesis concludes with a summary and perspectives of the future research of the field.更多还原
