【摘要】：我国经济建设飞速发展，随之而来是一些大中城市交通问题的日益严重，为了缓解市中心交通压力，绕城高速公路成为了重要的选择。绕城高速公路一方面连接放射线高速公路、国省道，另一方面又与城市道路相连，连接的道路类型复杂，涉及的区域广，需要指示的信息量较大，沿线互通立交数量多、形式多样，立交出入口间距小，指路标志常常出现信息量过载、信息缺乏连续性、信息的层次不分明等诸多问题。解决好如上问题，才能实现绕城高速公路的交通功能。论文依托陕西省交通厅2012年度交通科技项目，通过归纳总结国内外指路标志应用现状及相关规范发展状况，融合交通心理学、交通工程学、交通安全学及信息论等其他学科的相关知识，对绕城高速公路指路标志进行优化设计。论文首先确定绕城高速公路指路标志中的重要原则，分析驾驶人的认知过程及不同交通流的信息需求，在此基础上对绕城高速公路节点进行划分，将绕城高速公路节点划分为枢纽立交、次枢纽立交及一般立交，并对不同节点版面的设置位置及支撑方式进行分析。其次，在数字化交通标志应用趋势的大背景下，综合国内外专家研究情况确定指路标志信息阈值，给出建议的信息数量阈值为6-9条，并对指路信息进行分级，给出陕西省高速公路指路信息分级建议表，在此基础上确定绕城高速公路信息分级方法，，并针对不同立交节点确定版面信息量。再次，论文在确定指路标志信息质量优化思路及原则的基础上，将绕城高速公路优化分为节点单元和主线单元，针对不同类别立交形式进行优化设计，并对指路标志相关的主线标志信息进行分析。论文最后以西安绕城高速公路为例，分析西安绕城高速公路的交通功能，确定优化内容，并选取六村堡立交和长安立交作为不同类型立交节点的代表进行优化设计。
[Abstract]:With the rapid development of economic construction in China, traffic problems in some large and medium-sized cities are becoming more and more serious. In order to alleviate the traffic pressure in the city center, the highway around the city has become an important choice. On the one hand, the highway around the city is connected with the radiation highway, the national provincial highway, and on the other hand, it is connected with the urban road. The road type is complex, the area involved is wide, the amount of information needed to be indicated is large, and the number of interchanges along the route is large. There are many problems, such as various forms, small distance between interchanges, overloading of information, lack of continuity of information, lack of clear level of information and so on. Solve the above problem well, can realize the traffic function of the highway around the city. Based on the 2012 transportation science and technology project of Shaanxi Provincial Communications Department, this paper summarizes the current situation of the application of road guide signs at home and abroad and the development of related norms, and integrates traffic psychology and traffic engineering. The related knowledge of traffic safety and information theory, etc., to optimize the design of highway guide sign. Firstly, the paper determines the important principles in the guide sign of the roundabout highway, analyzes the cognition process of the driver and the information demand of the different traffic flow, and then divides the nodes of the highway around the city. The paper divides the nodes of the highway around the city into the junction interchange, the secondary hub interchange and the general interchange, and analyzes the layout position and supporting mode of different nodes. Secondly, under the background of the application trend of digital traffic signs, synthesizes the domestic and foreign experts' research situation to determine the information threshold of the road signs, gives the suggested threshold of information quantity is 6-9, and classifies the information of the directions. This paper gives the suggestion table of highway information classification in Shaanxi province, and on the basis of this, determines the classification method of highway information around the city, and determines the layout information content for different interchange nodes. Thirdly, on the basis of determining the ideas and principles of the information quality optimization of the guide signs, the paper divides the optimization of the surrounding highway into node unit and main line unit, and optimizes the design for different types of interchange. And the main line sign information related to the guide sign is analyzed. Finally, taking Xi'an Expressway around the City as an example, this paper analyzes the traffic function of Xi'an Expressway, determines the optimization content, and selects six villages Fort Interchange and Changan Interchange as representatives of different types of interchange nodes to optimize the design.
