摘要
我国高速公路上的可变信息标志主要以文字形式发布信息。但是,利用文字传递信息往往受到显示空间以及驾驶员视认能力的限制,显示的文字个数十分有限,不利于驾驶员获取全面的信息。在总结欧洲、美国、日本等国外可变信息交通图形标志现状和国内现状的基础上,提出了国内目前高速公路可变信息交通标志存在的主要问题,同时对高速公路可变信息交通图形标志进行了需求分析。对目前高速公路可变信息交通图形标志的发展研究有一定的借鉴意义。
At present,variable information signs on expressways in China mainly release information in written form.However,the use of characters to deliver information is often limited by the display space and the drivers visual recognition ability,and the number of characters displayed is also very limited,which is not conducive to the drivers for receiving comprehensive information released.On the basis of summarizing the current situation of variable information traffic graphical signs in Europe,the United States,Japan and other foreign countries and the domestic situation,this paper puts forward the main problems of variable information traffic graphical signs in domestic expressways,at the same time,analyzes the demand of that signs.It can be used as a reference for the research on the development of variable information traffic graphic signs on expressways.
