高速公路指路标志视认性改善研究与实践

Research and Practice on Visibility Improvement of Freeway Traffic Signs

在分析高速公路指路标志视认性现存问题的基础上,从标志的信息量、关联性以及新技术等方面研究相应的改善途径,并结合G12(珲春—乌兰浩特)高速公路长春东互通立交指路标志改造工程案例特点,提出了该互通立交的指路标志系统的优化改造方案,在提高标志视认性的同时,保证了行车效率与安全。

According to the analysis on current problems of the freeway traffic signs visibility, this paper has researched an effective approach in three aspects: quantity and relevance of guide signs information, new technology. In the actual project cases of Changchun highway, an optimization solution for guide sign system of the adjacent interchange has been proposed, so the signs visibility has been improved, thus guaranteeing the driving safety and efficiency.
