【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。
[Abstract]:As clothing, food, shelter and transportation, transportation is very necessary. As we all know, the whole traffic environment is in short supply at present. Whether it is highway or city road, the complexity of traffic is increasing, so it is more difficult to keep the traffic stable to a healthy and stable state. Traffic signs play a significant role in helping traffic managers to solve traffic problems. Traffic signs play an irreplaceable role in traffic management behavior such as traffic flow guidance, road traffic guidance information release, traffic accident reporting and so on. Variable information sign is the result of the new era and new demand of traffic sign. Variable information sign can make the information move in real time, can improve the efficiency of information utilization, and react more quickly to the change of road traffic. The luminance control of variable information symbol is studied in this paper. Firstly, this paper analyzes the factors that affect the recognition of signs, including human, vehicle, road and environment. In addition, the paper also considers the influence of signs on the recognition of signs. Based on the analysis of the influencing factors of visual recognition based on the above variable information markers and combined with the driver's recognition model, a parameter model of the above factors is constructed, including text size, location determination and so on. Through the model calculation, the experimental parameters are controlled to make the experiment more close to the real environment, the experimental data record table is designed, the experimental data is recorded in detail, the reliability and validity of the experiment are guaranteed, and the experimental results are analyzed. In different environments, such as daytime, dusk and night, the paper makes a detailed study on the static visual recognition distance and brightness control index of traffic variable information sign, and finally obtains the display brightness of traffic sign based on visual recognition. The paper has practical reference significance for the scientific setting of variable information sign of road traffic and the formulation of luminance evaluation standard.
