【摘要】：伴隨著城市化進程的迅速增長和經(jīng)濟的快速發(fā)展,各種類型的道路線性也越來越多,駕駛員在行進到該路段時難以辨識道路情況,因此,交通標志需要提供的信息量變得越來越多,越來越大,開始不能滿足現(xiàn)有路況。通過研究分析發(fā)現(xiàn)了影響交通標志信息量閾值的幾大因素,同時又發(fā)現(xiàn)現(xiàn)行的標準之中對于標志牌中漢字字體的使用定義比較籠統(tǒng),且對于單一標志牌中信息量為多少屬于不合理沒有明確規(guī)范,于是將這些未作具體規(guī)定的影響標志信息合理性的變量作為本論文研究的重要參數(shù)。本論文在實驗中對標志牌的設計和制作作了詳細的分析,分別設置了黑體、宋體和楷體三種字體下的標志牌,并且每種標志牌的字體大小又分為速度為40km/h、60km/h、80km/h及100km/h四種,選擇了標志漢字比較大的一個信息量區(qū)間設計了7組漢字字數(shù),用AUTOCAD制作了84個用于實驗的不同標志牌。然后利用道路建模工具和multigen-creator軟件建立好實驗場景模型,并將84個標志牌模型生成.ive格式文件后導入場景,綁定好用于反應時間采集的藍牙開發(fā)板的數(shù)據(jù)傳送模塊,同時組織了20名駕駛員對這幾組模型進行仿真實驗,經(jīng)過數(shù)據(jù)處理后發(fā)現(xiàn)交通標志中最為合理的常見字體為黑體,而且標志牌的合理信息量的最大值與道路的設計速度有相應的關系。最后對實驗數(shù)據(jù)處理中所得到的結論設計了一個驗證實驗,并設置了一組對比組,用以檢驗實驗結論的可行性。
[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.
