【摘要】：随着各大城市交通需求日益增长,交通问题也日益凸显,作为城市路网的主骨架,快速路的运行效率直接影响着城市交通的整体效率,因此加快快速路建设是新时代的发展趋势。按照设计要求,快速路应为城市交通提供便捷、舒适、安全、高效的行驶环境,但随着交通量的迅猛增长,建设快速路的速度远不能满足交通需求增长的速度,其拥堵的问题也日益严重。在城市交通路网背景下,本文从快速路的概念定义、功能定位和交通特性着手,分析了快速路和城市其它道路衔接时存在的交通问题,并据此提出了对快速路进行优化的主要思路。以简单实用的原则构建适用于不同地点,不同路况的快速路与被交路衔接区域的协调控制策略和优化方法。系统研究快速路出、入口匝道与被交路衔接交叉口的局部单点控制方法,并对比分析了单点控制的各种算法;基于快速路与被交路交叉口范围内单点控制效果显著但整体控制效果不理想的情况,本文在对单点控制方法分析的基础上,提出了协调控制的理念与方法。二环路作为西安市的交通要道,承载着西安内外很大一部分交通流的疏散,但近年来交通拥堵日益严重,且随着昆明路等快速路项目的建设,围挡封路进一步加剧了交通的拥堵。本文以西安市昆明路与西二环快速干道衔接区域—金光门立交为例,对西二环及沿线区域拥堵情况进行现场考察,并借助Google Earth、百度地图等软件对道路情况进行分析,提出了针对快速路与被交路衔接区域常见的平行式匝道菱形立交形式优化改造的方案和措施。论文的研究内容、方法和结论是对快速路与被交道路优化改造方法的一个探索,对解决快速路与被交道路衔接区域的拥堵问题具有一定的借鉴意义。
[Abstract]:As the main framework of urban road network, the operation efficiency of expressway has a direct impact on the overall efficiency of urban traffic.Therefore, speeding up the construction of expressway is the development trend of the new era.According to the design requirements, the expressway should provide a convenient, comfortable, safe and efficient driving environment for urban traffic. However, with the rapid growth of traffic volume, the speed of constructing expressway is far from meeting the increasing speed of traffic demand.The problem of congestion is becoming more and more serious.Under the background of urban traffic network, this paper analyzes the traffic problems existing in the connection between expressway and other urban roads, starting with the concept definition, function orientation and traffic characteristics of expressway.Based on this, the main idea of optimizing the expressway is put forward.Based on the simple and practical principle, the coordinated control strategy and optimization method for the link area between the expressway and the intersected road in different locations and different road conditions are constructed.The local single point control method of expressway exit, on-ramp and intersected intersection is studied systematically, and various algorithms of single point control are compared and analyzed.The second Ring Road, as the main road of Xi'an City, carries a large part of the evacuation of traffic flow inside and outside Xi'an. But in recent years, the traffic congestion is becoming increasingly serious, and with the construction of the Kunming Road and other expressway projects,The traffic jam was further aggravated by the blocking of roads.In this paper, taking Jinguangmen Interchange as an example, the traffic congestion in the west second ring and along the west second ring is investigated, and the road situation is analyzed with the help of Google, Baidu map and other software, such as the connecting area of Kunming Road and the West second Ring Express Road, as an example, the paper takes the Jinguangmen Interchange as an example.The scheme and measures for optimizing the rhombic interchange of parallel ramps in the connection area between the expressway and the intersection are put forward.The research contents, methods and conclusions of this paper are an exploration for the optimization and reconstruction of the expressway and the intersected road, and can be used for reference to solve the congestion problem in the junction area between the expressway and the crossing road.
