The subway station sign system is an important part of the research of the subway station design, and the research results have been increasing since twenty-first century in China. In terms of the number of published papers, the research on the subway station sign system based on pedestrian simulation has become a hot research topic. However, the domestic research is at the initial stage and the mature research results is relatively small. The researchers should pay more attention to the processing of the data with the help of simulation platform in future.
