【摘要】:我國經(jīng)濟建設飛速發(fā)展,隨之而來是一些大中城市交通問題的日益嚴重,為了緩解市中心交通壓力,繞城高速公路成為了重要的選擇。繞城高速公路一方面連接放射線高速公路、國省道,另一方面又與城市道路相連,連接的道路類型復雜,涉及的區(qū)域廣,需要指示的信息量較大,沿線互通立交數(shù)量多、形式多樣,立交出入口間距小,指路標志常常出現(xiàn)信息量過載、信息缺乏連續(xù)性、信息的層次不分明等諸多問題。解決好如上問題,才能實現(xiàn)繞城高速公路的交通功能。 論文依托陜西省交通廳2012年度交通科技項目,通過歸納總結國內外指路標志應用現(xiàn)狀及相關規(guī)范發(fā)展狀況,融合交通心理學、交通工程學、交通安全學及信息論等其他學科的相關知識,對繞城高速公路指路標志進行優(yōu)化設計。 論文首先確定繞城高速公路指路標志中的重要原則,分析駕駛人的認知過程及不同交通流的信息需求,在此基礎上對繞城高速公路節(jié)點進行劃分,將繞城高速公路節(jié)點劃分為樞紐立交、次樞紐立交及一般立交,并對不同節(jié)點版面的設置位置及支撐方式進行分析。其次,在數(shù)字化交通標志應用趨勢的大背景下,綜合國內外專家研究情況確定指路標志信息閾值,給出建議的信息數(shù)量閾值為6-9條,并對指路信息進行分級,給出陜西省高速公路指路信息分級建議表,在此基礎上確定繞城高速公路信息分級方法,并針對不同立交節(jié)點確定版面信息量。再次,論文在確定指路標志信息質量優(yōu)化思路及原則的基礎上,將繞城高速公路優(yōu)化分為節(jié)點單元和主線單元,針對不同類別立交形式進行優(yōu)化設計,并對指路標志相關的主線標志信息進行分析。論文最后以西安繞城高速公路為例,分析西安繞城高速公路的交通功能,確定優(yōu)化內容,并選取六村堡立交和長安立交作為不同類型立交節(jié)點的代表進行優(yōu)化設計。
[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.
