作为智能交通系统的一部分,在电子信息板显示的电子交通标识,由于能够为驾驶员提供清晰、准确且易于辨识的交通信息,在世界各地得到了日益广泛的应用.本文对韩国首尔市动态交通控制系统中的电子交通标识进行评价和设计.对之前研究中设计的部分标识改进,并在实际某路段的可变信息板显示试验.此外,通过部分驾驶员对这些交通标识的辨识进行分析,对不同方案进行评价,为确定最终的标识提供参考.结果表明,现有欧洲设计和韩国设计的表示交通事故的标志辨识正确率较低(分别为10%和43.5%);表示拥堵和交通事件的标志辨识正确率在45%至55%间;欧洲设计的雪天警告标志的辨识正确率为17.5%,韩国设计的雪天警告标志相对易于辨识(正确率75.5%).
As part of ITS, the electronic traffic sign displayed on the electronic information board has been widely used all over the world because it can provide the driver with clear, accurate and easily recognizable traffic information.This paper analyzes the dynamic traffic Control the system of electronic traffic signs for evaluation and design.On the previous study, part of the logo design to improve, and in a practical section of the variable information board display test.In addition, some of the drivers to identify these traffic signs to be analyzed, Different schemes were evaluated to provide a reference for determining the final marker.The results showed that the current design of Europe and the South Korea designed marker for traffic accidents have lower accuracy (10% and 43.5% respectively); traffic jam The accuracy rate of snow warning signs designed in Europe is 17.5%. The snow warning signs designed in Korea are relatively easy to identify (the correct rate is 75.5%).
