【摘要】：高速公路施工区标志牌传递着行进的方向及距离等信息,为车辆安全、有效、便捷的通过施工区提供了必要的保障。本文从驾驶员的视认特性出发,分析了驾驶员对施工区标志牌的视认过程及眼动规律,根据国内外相关规范规程,拟定施工区标志牌的设计及布置方案,通过室内驾驶模拟眼动试验,进行比选并提出建议方案。首先,本文通过对比我国相关高速公路施工规范及规程,选取需要研究的施工区标志。通过对驾驶员在对施工区标志标牌的视认过程以及驾驶员眼动规律的分析,选取施工区标志累计注视次数、初始注视时间、平均注视时间、平均注视间隔时间为评价施工区标志设计与布置合理性和安全性的视认特性指标。其次,在分析交通标志三要素的基础上,根据国内外相关规范从颜色、形状角度设计了15种不同的施工区施工、限速、线形诱导标志进行室内驾驶模拟试验,选取相应的视认指标进行研究分析,得出菱形黄色施工标志、蓝色线形诱导标、圆形红色限速标志视认性最好的结论。再次,分析了我国各种规范规程中对施工区施工、限速标志布置的相关要求,同时借鉴《美国统一交通控制手册》(2009),本文设计了9种不同的试验方案进行室内驾驶模拟试验,并基于眼动指标参数的处理分析,得出施工标志、限速标志位置布置的建议值。最后,根据室内驾驶模拟器所记录的车辆运行速度,通过对施工区速度分布进行Pareto图以及统计描述分析,验证了基于驾驶员视认特性施工区标志牌设计、布置方案的合理性和有效性。本文所取得的研究成果可为高速公路施工区标志系统的规划配置提供参考。
[Abstract]:The signboard of expressway construction area conveys the information of direction and distance, which provides the necessary guarantee for the safety, efficiency and convenience of passing through the construction area. Based on the recognition characteristics of the driver, this paper analyzes the recognition process and eye movement law of the driver to the construction area sign, and draws up the design and arrangement scheme of the construction area sign according to the relevant rules and regulations at home and abroad. Through indoor driving simulation eye movement test, compare and select and put forward the proposal. First of all, by comparing the relevant highway construction codes and regulations in China, this paper selects the construction area signs that need to be studied. Based on the analysis of the recognition process and the eye movement law of the driver, the cumulative fixation times, the initial fixation time and the average fixation time are selected. The mean fixation interval is an index of visual recognition characteristics to evaluate the rationality and safety of the design and layout of construction area signs. Secondly, on the basis of analyzing the three elements of traffic signs, according to the relevant codes at home and abroad from the color and shape point of view, designed 15 different construction areas, speed limit, linear guidance signs for indoor driving simulation test, Selecting the corresponding visual recognition index to study and analyze, we can draw the conclusion that the rhombus yellow construction mark, the blue linear guide mark and the circular red speed limit mark have the best visual recognition. Thirdly, this paper analyzes the related requirements of construction and speed limit sign layout in various specifications of our country, and draws lessons from the uniform Traffic Control Manual (2009), and designs nine different test schemes to carry out indoor driving simulation test. Based on the processing and analysis of eye movement index parameter, the suggestion value of construction sign and speed limit sign location arrangement is obtained. Finally, according to the vehicle running speed recorded by the indoor driving simulator, through the Pareto diagram and statistical description analysis of the speed distribution in the construction area, the design of the construction area marker based on the driver's recognition characteristics is verified. The rationality and effectiveness of the layout plan. The research results obtained in this paper can provide a reference for the planning and configuration of expressway construction area marking system.
