Study on the Safety and Disaster-Prevention Signing System of the Subway Based on Site Investigation at Home and Abroad

The subway has become an important form of transportation in our daily life. And the sign system is a part of the subway engineering, which plays an important role in improving the convenience and the efficiency of emergency dispersion. In the present paper, by site investigation of the subway sign system at home and abroad, such as Busan & Seoul (Korea), Tokyo (Japan), Beijing & Nanjing(China), analysis were made on the subway sign system of the cities mentioned above. On the basis of cognitive psychology and human body engineering, suggestions on the subway sign planning and design were made, which contain subway sign location, the impact of billboards on the signs, the relevance between the sign and the device and so on. The optimization suggestions on subway sign design are proposed to make it functional, systematic, international, concise and humanistic.
