【摘要】 作为关乎民众日常生活的衣、食、住、行这四个大类,交通承担着十分必要的任务。众所周知,目前整个交通环境呈现着供不应求的状况,无论是高速公路还是城市道路,交通的复杂度均是越来约大,保持交通稳定到一个健康、平稳的状态运行也是更加困难。交通标志在帮助交通管理者治理交通问题时作用显著,交通标志对交通流诱导、道路交通指路信息发布、交通事故通报等交通管理行为扮演着不可替代的角色。可变信息标志是交通标志新时代新需求下的产物,可变信息标志可以做到信息发步的实时性,可以提高信息利用效率,对道路交通的变化反应更加快速。论文针对可变信息标志的发光亮度控制进行了研究。首先分析了各种影响视认标志的因素,从人、车、路、环境四个方面展开介绍了对于可变信息标志的视认干扰,除此之外,论文还考虑了标志自身对标志视认的影响。基于以上可变信息标志的视认影响因素分析,结合驾驶人的视认模型,构建了关于以上影响因素的参数模型,包括文字大小、位置确定等。通过模型计算,控制实验参数,使实验更加贴近真实环境,设计实验数据记录表格,详实记录实验数据,保证了实验的可靠性和有效性,对实验结果进行了数据分析。论文分别在白天、黄昏、夜晚等不同环境下,对交通可变信息标志的静态视认距离和亮度控制指标做了详细研究,最后得出了基于视认最佳的可变信息交通标志的显示亮度。论文对于道路交通的可变信息标志的科学设置和亮度评价标准的制定均具有现实参考意义。更多还原

【Abstract】 As a matter of people’s daily lives of clothing,food,housing,travel these four categories,the traffic has a very necessary task.As everyone knows,the traffic environment has a short supply situation,whether highway or city roads,traffic complexity is increasing,to keep the traffic stability as a healthy and stable running state is more difficult.Traffic signs effect significantly when traffic managers’ governance the traffic problem,traffic signs on road traffic flow guidance,information release,traffic accidents and other traffic management behavior plays an irreplaceable role.Variable message sign is the result of the traffic signs under the new era demand,it can send real-time information and improve the utilization efficiency of information,faster response to changes in road traffic.In this paper,the luminance control of variable message sign is studied.First analyzes the various factors that influence the visual cognition,from the people,vehicles,roads to environment four aspects are introduced for visual cognition disturbance to variable message sign,in addition to this,this article also considers the effect of the symbol sign itself to visual cognition.Based on the analysis of the influencing factors of the visual information,combined with the driver’s visual recognition model,the parameter model of the above influencing factors is established,including the text size,location determination and so on.Through the model calculation to control the experimental parameters,it makes the experiment closer to the real environment.This paper also designs the experimental data record form and detailed records experimental data to ensure the reliability and validity of the experimental.The result of the experiment data is analyzed.Static visual cognition distance and brightness control index of variable message sign is studied in detail respectively under different environment such as the daytime,evening and night.Finally,it is concluded that the display brightness of variable information traffic signs based on the best visual cognition.This paper has practical reference value for scientific setting of variable information sign and drafting of brightness evaluation standards.更多还原
