【摘要】：城市轨道交通是具有运量大、效率高等特点新型公共交通方式，近年来已经在全国各大中城市普及，并且越来越多的城市也在把规划修建城市大型轨道交通项目作为缓解城市日益增长的交通矛盾的重要措施。但是由于轨道交通本身建设范围大，建设期长、耗费人力物力大、对城市路网要求高等因素，导致轨道交通在施工期间将会对城市的交通尤其是老城区的交通带来巨大的压力，如果施工期间没有进行合理有效的交通组织，，那么城市交通将面临瘫痪的境地。本文是以工程应用为特点的工程硕士论文，因此文章关注点在于将科学理论应用到实际方案设计中，通过结合交通工程学、城市交通规划学、交通工程设施设计学、城市轨道交通学等多个学科的理论知识，最终归纳总结并应用到兰州轨道交通1号线东方红广场站施工期间的交通组织方案设计实证中。文章首先从轨道交通的施工环境入手，针对施工环境中不同的分类进行了较为细致的研究，施工环境的不同直接影响到施工期间交通组织方案设计的合理性，在对施工环境进行研究分析的同时，还需要收集和整理大量的基础数据，这些基础数据有很大一部分也将成为后期处理模型时所用到的基础数据；其次，文章针对轨道交通施工的工法进行了研究，不同的施工工法需要的工期各不相同，并且产生的交通影响大小及范围也各不相同，因此施工工法的选择也是交通组织方案制定的重要参考条件；再次，制定轨道施工期间的交通组织方案需要以施工期间的道路通行状况作为基本前提，因此对施工期间的交通量必须进行专业的预测，本文通过运用国内较为常用的背景OD矩阵推算方法对现状背景OD进行了推算得到了基础OD数据，之后通过交通仿真软件TransCAD对所基础OD进行预测，得到了轨道施工期间的背景OD，最终将这个OD量重新分配到了路网上得到了预测年的路网饱和度。最后在以上理论研究的基础上，文章以兰州市轨道交通1号线东方红广场站施工期间的交通组织方案设计作为实证将理论运用到工程实践当中，首先科学的确定了施工期间的交通影响范围，对影响区域内的主要道路及交叉口进行了梳理；随后对交通影响范围内所有路网以及交叉口的相关基础数据进行调查统计，并以这些数据为依据对路网现状饱和度及施工期间的饱和度进行推算；根据推算得到的施工期间路网饱和度信息，引入单向交通理念以及道路分流理论并结合相关道路设计规范对影响区域内的道路和交叉口进行了新的渠化设计，为制定施工期间的社会车辆及公交车辆的疏导方案提供了重要的道路条件；最终运用交通仿真软件Vissim对交通组织方案的各个交通指标进行综合评价，并提出相关建议供决策者参考。
[Abstract]:Urban rail transit is a new type of public transportation mode with the characteristics of large volume and high efficiency. In recent years, it has been widely used in large and medium-sized cities throughout the country. And more cities are also planning to build urban rail transit projects as an important measure to alleviate the growing urban traffic conflicts. However, due to such factors as large construction scope, long construction period, large manpower and material resources, and high demand for urban road network, rail transit will bring great pressure on urban traffic, especially in old urban areas, during the construction period. If there is no reasonable and effective traffic organization during construction, urban traffic will be paralyzed. This paper is a master of engineering thesis characterized by engineering application, so the focus of this paper is to apply scientific theory to practical project design, by combining traffic engineering, urban traffic planning, traffic engineering and facility design. The theoretical knowledge of urban rail transit and other disciplines is summed up and applied to the traffic organization scheme design of Dongfanghong Square Station of Lanzhou Rail Transit Line 1 during the construction period. This paper begins with the construction environment of rail transit, and makes a detailed study on the different classification of construction environment. The difference of construction environment directly affects the rationality of traffic organization scheme design during construction. While researching and analyzing the construction environment, we also need to collect and organize a large amount of basic data, which will become the basic data used in the post-processing model. In this paper, the construction method of rail transit is studied. The construction period of different construction method is different, and the traffic influence and scope are different. Therefore, the selection of construction method is also an important reference condition for the formulation of traffic organization plan; thirdly, the road traffic situation during the construction period should be taken as the basic premise for the formulation of the traffic organization plan during the track construction. Therefore, the traffic volume during construction must be predicted professionally. In this paper, the basic OD data are obtained by using the background OD matrix calculation method, which is commonly used in China, to calculate the background OD of the present situation. After that, the basic OD is predicted by the traffic simulation software TransCAD, and the background ODs during the track construction period are obtained. Finally, the OD value is reallocated to the road network to obtain the road network saturation for the predicted year. Finally, on the basis of the above theoretical research, this paper applies the theory to engineering practice by taking the traffic organization scheme design of Dongfanghong Square Station of Lanzhou Rail Transit Line 1 during the construction period as an example. Firstly, it scientifically determines the scope of traffic impact during construction, combs the main roads and intersections in the affected area. Then, it investigates the basic data of all road networks and intersections in the traffic impact area. Based on these data, the saturation of the road network and the saturation during the construction period are calculated, and the saturation information of the road network during the construction period is calculated. This paper introduces the theory of one-way traffic and the theory of road shunt and combines the relevant road design code to carry out a new channelization design of roads and intersections in the affected areas. It provides an important road condition for drawing up the plan of social vehicles and public transport vehicles during the construction period. Finally, the traffic simulation software Vissim is used to comprehensively evaluate the traffic indexes of the traffic organization scheme. And put forward relevant suggestions for the reference of decision makers.
