【摘要】 为缓解越来越大的城市交通压力,近年来,我国很多大城市开始了快速路的建设；然而,随着快速路交通量的增加出现了很多问题,这些问题主要集中在快速路的出入口处；另外,目前国内对于快速路规划与设计标准还有许多不完善的地方,这严重影响了城市快速路系统整体效益的发挥。因此,对城市快速路出入口设置相关问题的研究对城市快速路的建设有重要的指导意义,对城市快速路路网系统效益的发挥也起到了很大的作用。论文首先对快速路出入口处存在的各种交通问题进行整理,然后从车辆运行轨迹及衔接段交通流线的角度来分析这些交通问题产生的机理,然后对出入口设置的内容做了归纳,从三个方面来分别研究快速路出入口的设置。在快速路出入口位置的选定方面,对于节点立交的位置,论文以定性和定量相结合的方法确定互通立交的位置。定性分析是以交通区位理论为基础,定量分析则引入了重要度的概念,两者互相补充；对于路段出入口,则根据各种组合类型的出入口的最小安全间距来确定两相邻互通立交之间出入口的最大数量,然后分析了主线交通量与路段出入口数量的关系。快速路出入口立交型式的选择上,首先分别介绍了常用的四种立交型式的优缺点及其适用条件,然后从相交道路等级的不同、交通流量流向大小的不同和用地限制等方面来确定立交的型式。论文还根据互通式立交间距的合理与否提出了组合式立交的使用,并举例加以论证。快速路出入口处交通设计主要包括车道的设计和交通组织设计两个部分,论文中针对不同的交通组合类型,对其出入口处交通组织方式进行了分析,并对衔接段处的交通组织进行了研究。论文最后以北京二三环为例,从二三环的区位位置、二三环上交通问题及分析、二三环上出入口的数量及出入口处的交通组织方法等方面来说明本文所论述内容的合理性。更多还原

【Abstract】 In recent years, many large city began the construction of urban expressway to release the increasing pressure on the urban transport in China; in the other hand, there have been lots of problems arising due to the pressure of the increasing traffic flow in the urban expressway network, and these problems exist mostly in the area of the exit and entrance; in addition, because of the specification which is imperfections about the urban expressway, resulting in more and more problems at the exit and entrance, it seriously impacts the efficiency of the urban expressway network. Therefore, it’s significance to study on establishment with related issues at the entrance and exit of urban expressway and will play a large role to benefit from the urban expressway network.First, the paper sorts the existing problems at the entrance and exit, and then analysis the source of these problems by vehicle trajectory and traffic flow line. Then, the contents of this paper were summarized, and the article is divided into three parts to be studied.In the aspect of the location of entrance and exit, for the interchange nodes, the paper studied the location of interchange with a combination of qualitative and quantitative method to determine the location of Interchange. Qualitative analysis is based on the traffic location theory, and quantitative analysis is the introduction of the concept of an important degree. For the entrance and exit which is at the road section, the paper quantify the entrance and exit according to various combinations of types of entrances and exits, then trying to build the relationship between traffic and the optimal quantity to calculate optimal quantity.In the aspect of selections of interchanges, the paper introduced the advantages and disadvantages and the application conditions of several commonly used types of interchanges, and then determined the interchange type from the following aspect:the level of the intersecting road, traffic flows and land-use restrictions and so on. The paper also demonstrated the application of composite interchange according to two examples.The design of the entrance and exit mainly include the design of the lanes and the traffic organization design, the paper analyzes the traffic organization design at the entrance and exit for different types of entrance and exit combinations.At last, the paper takes ring road of Beijing as an example from the location of the ring road, the problem of the entrance and exit, the traffic organization design to prove the previous contents feasible.更多还原
