【摘要】：随着首都北京近些年来经济建设的飞速发展,城镇化水平的不断提高,根据早期规划设置的道路条件,难以满足当前的交通需求。北京市内部分地区早晚高峰的拥堵状况十分严重,尤其是重点路口及路段的关键节点,更加突出,因此对于市区拥堵路口及路段节点工程改造及优化组织显得尤为重要。交通拥堵问题是由路口、路段及区域路网形成的系统问题。可以通过对拥堵路口及路段节点工程优化改造,来缓解拥堵点(段)的交通压力。同时兼顾远期,不断的通过基本的点、线的改造来完善面,以达到缓解区域拥堵的目的。拥堵路口及路段节点工程优化改造,主要是通过对项目资料收集与实地调研相结合等方法,根据路网特性和交通需求,对于拥堵节点及路段产生拥堵的原因进行了剖析,合理设计疏堵方案。文中针对路口及路段道路设计方面,总结出路口通行能力、路口范围冲突、路口交通组织、路口配时、桥下空间利用、公交站台设置、过街设施及交通配套设置等多方面原因。同时,结合交通理论进行研究,提出拥堵路口及路段节点改造工程的原则与改造措施:优化道路交叉口交通组织——保证路口通畅性;改善道路交叉口交通组织——减少交通冲突;新建改建公交港湾及站台——提倡公交优先;完善行人过街、完善行人、非机动车慢行系统——突出以人为本;完善交通工程配套设施——提高道路效率;桥下空间改造利用——充分利用现有道路资源等多项措施。并以六里桥南改造工程作为典型的交通疏堵改造工程案例进行研究,从提升通行能力、改善冲突、修建公交港湾、完善交通配套设施等多方面,系统的介绍交通疏堵改造工程的改造的方法,利用交通仿真软件,对交通运行特征进行分析,可为以后的类似工程提供实践改造经验和借鉴。
[Abstract]:With the rapid development of economic construction and the continuous improvement of urbanization in recent years, it is difficult to meet the current traffic demand according to the road conditions set up in the early planning. The morning and evening rush hour congestion in some parts of Beijing is very serious, especially the key nodes of key junctions and sections are more prominent, so it is particularly important for urban congested junctions and sections of joint engineering reconstruction and optimization organization. Traffic congestion is a systemic problem formed by intersection, section and regional road network. The traffic pressure can be alleviated by optimizing the joint engineering of congested junctions and sections. At the same time, take into account the long-term, through the transformation of basic points, lines to improve the surface, in order to alleviate the purpose of regional congestion. Based on the characteristics of road network and traffic demand, the paper analyzes the causes of congested nodes and road sections through the combination of project data collection and field investigation. Reasonable design of plugging scheme. Aiming at the design of intersections and road sections, this paper summarizes the traffic capacity of intersections, the conflict of intersections scope, the traffic organization of intersections, the timing of intersections, the utilization of space under bridges, the setting of bus stops, the facilities of crossing streets and traffic matching settings, and so on. At the same time, combining with the traffic theory, the paper puts forward the principles and measures for the reconstruction of congested junctions and road sections: optimizing the traffic organization at intersections to ensure the smooth flow of intersections; Improving traffic organization at road intersection-reducing traffic conflicts; constructing and rebuilding public transport harbors and platforms-advocating public transport priority; perfecting pedestrian crossing and pedestrian, non-motor vehicle slow moving system-giving priority to public transport; It is necessary to improve the supporting facilities of traffic engineering-to improve road efficiency, to make full use of existing road resources and to make full use of existing road resources. And take the south reconstruction project of Liuliqiao as a typical case of traffic diversion and reconstruction project, from the aspects of improving traffic capacity, improving conflict, building public transport harbor, perfecting traffic supporting facilities, etc. This paper systematically introduces the reconstruction method of traffic diversion reconstruction project, and analyzes the traffic operation characteristics by using traffic simulation software, which can provide practical reconstruction experience and reference for similar projects in the future.
