【摘要】 高速公路的建设在国民经济中起着十分重要的作用,特别是随着交通需求的不断增长和交通事件的不断发生,高速公路交通监控系统的智能化,正在成为交通管理部门的焦点,在国家颁布的《公路水路交通“十一五”发展规划》中明确提出了高速公路的智能交通技术要达到国际先进水平的建设目标。笔者以投入试运行的绵广高速公路交通监控系统项目为背景,针对目前我国高速公路交通监控系统在实际运营中反映出的功能结构化单一、信息利用率较低等问题,分析研究了国内外该技术的应用情况,在递阶智能控制理论,高速公路交通流模型和模糊控制理论的基础上,结合国情和多年工程实践的经验,给出了“基于递阶智能控制的交通监控方案”。本方案的提出由浅入深,层层递进。首先对绵广高速公路交通监控系统项目和国内外交通监控系统的发展进行了回顾,其次对“基于递阶智能控制的交通监控方案”的理论基础进行了说明,接着在定性分析了影响高速公路交通流的各种因素的前提下,设计了绵广高速公路的交通监控系统架构,然后应用模糊控制理论建立行驶线路中的最佳速度求解模型,通过在主线上交通流最佳速度的实时发布,达到总行程时间最小、服务流量最大的智能控制性能指标。更多还原

【Abstract】 Expressway has been playing an essential role in the national economy. In particular, as the continuing growth of transport demand and the frequently occurred traffic incident, the intelligence of expressway monitoring system gradually become the focus of traffic management. It also made clear that intelligent transportation technology of the expressway should achieve the international advanced level in the“The 11th Five-Year development planning of road and waterway traffic”publicized by state.This dissertation takes a monitoring system of Mian-Guang expressway in which the author participated as its background. Because of the simplification of functional structure and other issues, which the current expressway traffic control system in the actual operations reflected, after analysis the technical application at domestic and abroad, the author who coupled with the national conditions and long time engineering experience proposes "hierarchical intelligent control based traffic control program", based on the theory of intelligent coordination control and the fuzzy control and the model of expressway traffic flow.The program is proposed step by step. First, it review the development of Mian-Guang expressway traffic monitoring system project and traffic control systems at home and abroad. Second, it explain the basic theory of "hierarchical intelligent control based traffic control program". Then, on the qualitative analysis of the impact of freeway traffic flow of various factors, design the architecture of Mian-Guang expressway traffic control system architecture and give“optimum speed solving model of the running line”with the theory of fuzzy control. In this model, it got the minimum total journey time, largest service flow of intelligent control performance indicators through the real-time publication of the best velocity of traffic flow in the main line.更多还原
