摘要
城市道路交叉口指路标志信息认知的水平直接影响交通参与者寻路的安全性和舒适性.为此选取部分国家(中国、美国、日本、英国)、部分地区(北京、上海、武汉、南京)及新方案(4组)的城市道路交叉口指路标志进行案例分析.应用信息熵模型和人因工程学模型,定量评价其传递的交通信息的认知程度.当指路标志传递的信息需求程度较高且易于理解时,此信息认知的水平较高.
The cognitive level of information transferred by traffic guide sign at urban road intersections directly impacts the safety and comfort of roadway users finding path. This paper analyzes the traffic guide signs installed in urban arterial and minor roads in several countries （e. g. China, the U. S. , Japan and UK） and Chinese cities （e. g. Beijing, Shanghai, Wuhan and Nanjing） , as well as four new designs. The paper proposed using the information entropy model and human factors engineering model to quantitatively evaluate the cognitive level of information transferred by traffic guide sign. This research found that the cognitive level is higher when the information transferred by traffic guide sign meets the traffic participants＇ demand.
