【摘要】：道路施工前期,政府管理部门做出交通管理预案,向居民发布道路施工信息。但不是所有的出行者都能提前接收到信息,同时管理预案对具体绕行路径的指导作用不明显。由于非对称信息的作用,施工期间道路上存在受信息影响和不受信息影响这两种交通流,它们间的相互作用,无疑增加了道路交通流状况的复杂性。因此,研究非对称信息对交通流分配的影响,探究非对称信息作用下的交通流分布规律,对交通管理预案的制定及后期交通组织的调节,具有一定的指导作用。论文依托智能交通研究院开放课题“城市道路施工区域交通组织优化模型研究”内容展开研究,主要包括以下内容：1.通过分析道路施工期间交通管理者与出行者、出行者与出行者之间掌握道路施工信息的不同,总结了非对称信息的内容和分类,并解析了其对施工期间道路交通运行产生的不利影响。2.使用Transcad软件得到道路施工前、后影响范围边界上特征信号交叉口的高峰小时饱和度,以交叉口整体服务水平等级不下降作为收敛条件,建立了基于圈层外推的道路施工影响范围确定方法。3.道路施工易造成出行时间增长,通过引入“排斥度”系数,建立了非对称信息作用下道路施工期间多路径分配模型,使用Matlab软件编制了程序,计算并验证了利用该交通分配模型可有效分析道路施工期间非对称信息影响下的交通分配结果。4.结合模型计算结果中的交通量分配特性,通过研究“出行时间最短”和“道路状况更佳”这两种出行方式的特点,提出两种道路施工期间交通组织绕行诱导方法,并阐述了道路施工信息的发布、更新、再发布的流程。同时借助实例验证本文提出的非对称信息作用下的道路施工交通组织方法的实用性和有效性。
[Abstract]:In the early stage of road construction, the government management department makes traffic management plan and issues road construction information to residents. But not all travelers can receive the information in advance. At the same time, the guidance of management plan to the specific bypass path is not obvious. Because of the effect of asymmetric information, there are two kinds of traffic flow on the road during construction, which are affected by information and not affected by information, and the interaction between them exists. Therefore, the influence of asymmetric information on traffic flow distribution is studied, and the law of traffic flow distribution under asymmetric information is explored. To the traffic management plan formulation and the later stage traffic organization adjustment. It has a certain guiding role. The thesis is based on the content of the open topic of the Intelligent Transportation Research Institute, "the study of Regional Traffic Organization Optimization Model of Urban Road Construction". Mainly includes the following contents: 1. Through the analysis of the differences between traffic managers and travelers, travelers and travelers to master road construction information, summed up the content and classification of asymmetric information. And analyze its adverse impact on road traffic operation during the construction. 2. Using Transcad software to get peak hour saturation of the characteristic signal intersection on the boundary of the road construction before and after the road construction. Based on the convergence condition of the whole service level of intersection, the method of determining the influence range of road construction based on circle extrapolation is established. 3. The road construction is easy to cause travel time increase. By introducing the "degree of exclusion" coefficient, the multi-path distribution model of road construction period under the action of asymmetric information is established, and the program is compiled by using Matlab software. The results of traffic assignment under the influence of asymmetric information during road construction can be effectively analyzed by using the traffic assignment model. 4. Combined with the characteristics of traffic volume distribution in the calculation results of the model. By studying the characteristics of "shortest travel time" and "better road condition", this paper puts forward two kinds of traffic organization guidance methods during road construction, and expounds the release and update of road construction information. At the same time, the practicability and validity of the road construction traffic organization method under the action of asymmetric information are verified by an example.
