高速公路指路标志信息过载及缺失的分析及改善措施

A brief analysis and optimization measures on the information overload and lack in direction signs in highways

为规范高速公路中的标志设置,主要以交通标志中的指路标志为研究对象,通过对陕西省运营高速公路的实地调研,针对指路标志的信息过载及信息缺失这两类问题,结合陕西省高速公路现状,图文并茂的分析实例、找出问题症结、提出具体改善措施,对更好的发挥道路交通标志的管理功能和服务功能具有重要意义。

In order to standardize the direction sign panels setup in highways,mainly taking the direction sign panels of the transportation sign panels as the research object,through the field exploration of the running expressway in Shaanxi province and focusing on the two problems which are information overload and lack in the panels,considering the actual situations and facts existing in Shaanxi highways,analyzing the examples,digging out problems and bringing out improvement measures by charts,all of this makes great sense to making good use of management and service function of transportation sign panels.
