【摘要】：伴随我国社会经济的高速发展,道路交通进程的加快,部分城市为缓解城区交通压力,相继修建了多条环线快速公路。环线快速道路与市区道路、国省道、以及放射线高速公路相连,具有大型互通式中转立交,包括立交出入口多,环线涉及区域广、道路承接性要求高,指示需求信息量大等特征。因此,部分环线城市快速公路在修建通车后,指路标志设置常常出现版面信息量过载,出入口标志位置设置不规范,信息对象不明确等问题。怎样解决上述问题,成为城市快速道路标志设计发展面临的首要目标。成都市三环路正面临着环线快速公路存在的一致问题,直接导致不熟悉本地路网的驾驶员错失目的地,造成无谓的经济损失和时间的浪费。论文首先通过对三环道路路网环境及沿线交通组成分析,并结合指路标志设置现状的调查与总结,概括指出了指路标志设置存在的问题。在此基础上,论文对指路标志版面信息量进行了优化研究,并利用交通安全驾驶模拟平台,根据仿真驾驶行为人在不同版面的信息量差异情况下对版面信息的辨识程度以及驾驶操作时间的反应情况,采集实验所得数据并进行F检验及相关性分析；与此同时,论文对三环出口前置预告标志的设置距离进行Vissim仿真,就驾驶人员驶入快速道路出口的驾驶行为进行分析,并建立了快速道路出口预告标志设置距离的理论计算模型,通过Vissim对比仿真,根据不同AGS设置距离情况,驾驶员在驶出匝道过程中所产生的平均延误时间,得出了快速道路出口预告标志的合理设置范围。论文通过以上调查资料以及实验分析,结合国内外交通指路标志的设置研究经验,提出了三环指路标志设置的管理措施和合理化改进意见。
[Abstract]:With the rapid development of our country's social economy and the acceleration of road traffic process, in order to alleviate the traffic pressure in urban areas, some cities have built a number of loop expressway one after another. The Ring Line Expressway is connected with urban roads, national provincial highways, and radiation highways. It has a large interchange, including a large number of entrances and exits of interchanges, which involve a wide range of areas and require high road acceptance. Indicates the large amount of demand information and other characteristics. Therefore, some problems such as overload of layout information, irregular location of entrance and exit signs, unclear information objects and so on often occur after the construction and opening of some circular urban expressway. How to solve the above problems has become the primary goal of the design and development of urban expressway road signs. The third Ring Road in Chengdu is facing the consistent problem of the Ring Road Expressway which directly leads the drivers who are not familiar with the local road network to miss their destination resulting in meaningless economic losses and waste of time. Firstly, by analyzing the environment of the third Ring Road Network and the traffic composition along the road network, and combining with the investigation and summary of the present situation of the setting up of the guiding signs, the paper summarizes the problems existing in the setting of the guiding signs. On the basis of this, the paper optimizes the layout information of the guide sign, and makes use of the traffic safety driving simulation platform. According to the degree of identification of layout information and the reaction of driving operation time to different layout information, the simulation driver collects the experimental data and carries out F test and correlation analysis. This paper simulates the setting distance of the leading sign of the third ring exit by Vissim, analyzes the driving behavior of the driver driving into the exit of the fast road, and establishes the theoretical calculation model of the setting distance of the warning sign for the exit of the fast road. Through Vissim simulation, according to the different AGS setting distance, the average delay time of the driver in the course of off-ramp is obtained, and the reasonable setting range of the exit warning sign of the expressway is obtained. Based on the above investigation data and experimental analysis, combined with the research experience of traffic guide signs at home and abroad, the paper puts forward the management measures and rational improvement suggestions for the setting up of three-ring road signs.
