摘　　要：为进一步推进我国基于VMS的图形信息服务水平,对比研究了国内外VMS的应用规模现状、显示内容现状及图形标准化现状。研究结果表明与发达国家相比,我国高速公路的VMS覆盖率较低,发布信息仍以文字形式为主,图形信息的发布还没有统一标准可依。针对这一现状,结合我国现有标准,提出了适合我国现状的用于VMS信息发布的图形信息适用性判别准则,包括信息内容判别准则、信息分辨率判别准则及信息色彩判别准则。利用上述准则,对现行的部分警告标志、禁令标志、指示标志的适用性进行了分析,并基于现有图形标志,设计了相应的适用于VMS信息发布的图形标志,提升了图形信息的明显、易读、准确、简洁等特性,便于VMS的图形信息发布。In order to further promote graphical information service level based on VMS in China, we compared the application sizes, display contents and graphics standards of the graphical information at home and abroad. The result shows that comparing with developed countries, VMS coverage is low in expressway of China. Most released information is in text form, and there is no uniform standard for the release of graphical information. For this existing problem, combined with our existing standards, we proposed the applicability criterion of the graphical information which is fit for the information released by VMS in China, including the applicability criteria of information content, information resolution and information color. Then, using the above criteria, we analysed the applicability of partial existing warning signs, prohibition signs and directional signs. Finally, based on the existing signs, we designed corresponding graphic signs for VMS, which make the graphical information released by VMS more obvious, easy to read, accurate, and concise.
