摘要/Abstract

摘要： 作为智能交通系统的一部分，在电子信息版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%）。

Abstract: Pictograms have increasingly been used in electronic message display boards around the world as part of the intelligent transportation systems because they provide drivers with a clear and precise message that is easy to understand. This paper reports on an evaluation of pictograms for a dynamic traffic control system in Seoul, South Korea. In this study, some of the pictograms developed in an earlier study were redesigned and transferred to an actual variable message sign for a field test. In addition, a sample of drivers was asked to compare the pictograms to assist the research team in making the final selection. The study found that most of the pictograms were quite easy to comprehend. However, pictograms depicting accidents performed poorly, with only 10.0% and 43.5% of the participants correctly identifying the message conveyed by the European design and the existing Korean design respectively. The pictograms depicting congestion and traffic incidents also performed moderately, with only 45%-55% correctly identifying the message conveyed. Finally, the European design for snow warning performed poorly (17.5% correct) whereas the Korean design performed relatively well(75.5% correct).

Key words: pictogram, variable message signs, lane control systems, driver perceptions
