城市道路信号交叉口通行能力分析.doc

摘 要 城市道路信号交叉口是城市道路的重要节点，它把城市道路相互连接起来构成道路网，其通行能力直接影响城市道路的通达，交叉口的交通流密度过大，将会造成路口的拥挤与堵塞，影响城市道路的正常运行，而提高信号交叉口通行能力、减少交叉口停车与延误是城市道路交通追求的目标，鉴于此，本文以信号交叉口为研究对象，通过典型交叉口的调查，探究其通行能力，并分析信号交叉口的运行状况。 论文共分为五个部分，第一部分概述研究背景、研究意义及国内外通行能力研究概况；第二部分概括信号交叉口分类、服务水平分析、运行分析、通行能力研究方法以及影响信号交叉口通行能力的因素；第三部分以**市某信号交叉口为例，进行交通调查，计算交叉口的通行能力，分析交叉口的运行状况；第四部分针对目前我国城市信号交叉口的总体特性，分析提高信号交叉口通行能力的对策；第五部分总结全文。 关键词：城市道路；信号交叉口；通行能力 Abstract Signalized intersection is the important component of the urban road. It connects urban road up a road network, and its capacity directly affect the running efficiency of the urban road. Urban road will not work normally if the traffic congestion or jam happened to the signal intersection when the traffic flow desity of the intersection is too large. To improve the traffic capacity and reduce parking and delaying in the intersection are the goals of urban road traffic. For reason above, the signal intersection is studied as a research object, and the traffic capacity of intersection is explored. The running status of the signal intersectionis analyzed in this paper. This paper is divided into five parts. The first part summarizes the research background, the research significance and the domestic and foreign general capacity; The second part summarizes signal intersection classification, the service level analysis, operation analysis, capacity and influence factors of the Signalized intersection traffic capacity; The third part takes a signal intersection in Jinzhou. As an example, surveys the volume of traffic, calculates the capacity of signal intersection, analysis the status of the intersection; On the basis of the general characteristics of the urban road intersection, a number of countermeasures to improve signal intersection traffic capacity are analyzed in the forth part of paper; The fifth part summarizes the whole reserchers of the paper. Key words：Urban road；Signal intersection；Capacity 目 录 第1章 绪 论 1 1.1 研究背景 1 1.2 研究意义 2 1.3 国内外研究现状 3 1.3.1 国外研究现状 3 1.3.2 国
