【摘要】 在陕西省高速公路网不断完善,路网布局形式越来越复杂的情况下,现有国家标准和规范中的部分规定已不能满足高速公路路径指引标志的设置需要,路径指引标志的设置问题越来越突出。本论文针对陕西省高速公路路径指引标志设置技术展开研究。首先,论文根据现状调研和问卷结果,对陕西省高速公路路径指引标志存在的问题及其原因进行归纳总结。其次,针对高速公路路径指引标志的设置位置、版面信息和支撑方式存在的问题分别展开了改善研究。设置位置方面,基于驾驶员交通标志视认过程,分析和计算得到高速公路路径指引标志的竖向和水平可视认空间,以及非执行类、执行类路径指引标志的设置间距,在此基础上对路径指引标志的设置位置进行了改善。版面信息方面,基于城市位置,将高速公路分为城市间高速公路和与城市衔接的高速公路,根据驾驶员高速公路寻路模型和问卷调查结果分析了驾驶员的指路信息需求,建立了高速公路路径指引标志指路信息的分级和选取方法,据此对版面信息设置进行改善。支撑方式方面,根据陕西省存在的问题和实践经验,总结了各类支撑方式的适用情况。再次,建立了高速公路路径指引标志评价清单,以及高速公路路径指引标志设置水平评价体系,并基于集对分析法构建了设置水平评价模型。最后,以西安绕城环线曲江互通立交和主线为例,应用评价模型评价了此处路径指引标志的现状设置水平,并针对存在问题给出了改善实例。更多还原

【Abstract】 With the continuous improvement of the expressway in Shaanxi Province, the network layout is becoming more and more complex。The current national standards and norms have not meet the needs of the expressway guide signs setting layout requirement. The setting of the expressway guide signs is becoming more and more prominent. This paper studied the setting technology of expressway route guidance sign in Shaanxi province.First of all, according to the Current situation investigation and questionnaire survey, this paper current analyzed and summed up problems and the causes of expressway guide signs layout in Shaanxi Province.Secondly, it researched the improvement theory separately aiming at the existing problems of the expressway guide signs on setting position, guide information and supporting mode. On aspect of locating, based on driver’s traffic signs visual cognition process, tit analyzed and calculated the vertical and horizontal visibility space of expressway guide signs, and the separation distance for non-execution and execution expressway guide signs. And for guide information, based on the location of the urban, it divided expressway into two types: between urban and connected with urban, then analyzed drivers’ travel characteristics driving on different type expressway, and with the questionnaire result, it researched on the demand of guide information for different expressway to optimize expressway guide signs information classification and selection methods. On aspect of support mode, it draw on the experience of Shanxi Province and gave the application condition for different modes.Thirdly, it established the evaluation list and evaluation system for expressway guide sign, and based on Set Pair Analysis constructs the set evaluation model.Finally, choosing Qujiang interchange and the main line of bypass expressway in Xian as an example, using the evaluation model evaluate the situation of the route guidance sign setting effect, an optimization example is given for the existence of the problem.更多还原
