【摘要】：伴随着城市化进程的迅速增长和经济的快速发展,各种类型的道路线性也越来越多,驾驶员在行进到该路段时难以辨识道路情况,因此,交通标志需要提供的信息量变得越来越多,越来越大,开始不能满足现有路况。通过研究分析发现了影响交通标志信息量阈值的几大因素,同时又发现现行的标准之中对于标志牌中汉字字体的使用定义比较笼统,且对于单一标志牌中信息量为多少属于不合理没有明确规范,于是将这些未作具体规定的影响标志信息合理性的变量作为本论文研究的重要参数。本论文在实验中对标志牌的设计和制作作了详细的分析,分别设置了黑体、宋体和楷体三种字体下的标志牌,并且每种标志牌的字体大小又分为速度为40km/h、60km/h、80km/h及100km/h四种,选择了标志汉字比较大的一个信息量区间设计了7组汉字字数,用AUTOCAD制作了84个用于实验的不同标志牌。然后利用道路建模工具和multigen-creator软件建立好实验场景模型,并将84个标志牌模型生成.ive格式文件后导入场景,绑定好用于反应时间采集的蓝牙开发板的数据传送模块,同时组织了20名驾驶员对这几组模型进行仿真实验,经过数据处理后发现交通标志中最为合理的常见字体为黑体,而且标志牌的合理信息量的最大值与道路的设计速度有相应的关系。最后对实验数据处理中所得到的结论设计了一个验证实验,并设置了一组对比组,用以检验实验结论的可行性。
[Abstract]:With the rapid growth of urbanization and the rapid development of economy, there are more and more linear roads of various types, so it is difficult for drivers to identify the road conditions when they travel to the road. Traffic signs need to provide more and more information, beginning to be unable to meet the existing road conditions. Through research and analysis, several factors affecting the threshold value of traffic sign information are found. At the same time, it is found that the definition of Chinese character font in the current standard is quite general. And there is no clear criterion about how much information is unreasonable in a single sign, so the variables which do not specify the rationality of the sign information are regarded as the important parameters in this paper. In this paper, the design and manufacture of the signs are analyzed in detail, and the signs in bold type, song type and italics are set up respectively, and the font size of each sign is divided into four types: the speed is 40km / s / h, the speed is 60km / h / h, and the 100km/h is 80kmh / h, respectively. Seven groups of Chinese characters have been designed in a large information range of marked Chinese characters, and 84 different signs used in experiments have been made with AUTOCAD. Then using road modeling tools and multigen-creator software to establish a good experimental scenario model, and 84 sign model to generate .ive format file into the scene, then bind the data transfer module of Bluetooth development board used for the collection of reaction time. At the same time, 20 drivers were organized to carry out simulation experiments on these models. After data processing, it was found that the most reasonable font in traffic signs was bold type. And the maximum of the reasonable information of the sign has the corresponding relation with the design speed of the road. Finally, a validation experiment is designed for the conclusions obtained from the experimental data processing, and a group of contrast groups is set up to verify the feasibility of the experimental conclusions.
