Abstract:

This article explore how the interior of the subway, as an important urban public space and information dissemination medium, can improve its overly commercialized visual environment through effective visual design strategies, bring a good commuting experience to the public, and build a more humane and friendly public transportation space. From the perspective of media environment theory, the phenomenon of information overload and media imbalance in the subway space was analyzed, and concepts such as media preference and content bias were introduced to discuss the demand characteristics of the subway as a medium for information content in time and space, emphasizing the importance of artistic and public content as elements of subway internal visual design, and its practical application in the "Art Metro Train" project is summarized and analyzed. Through theoretical analysis and practical summary, this article proposes a design strategy to better balance the multiple functions of the subway inside and outside as public space and information transmission media, and provides relevant management departments and design teams with feasible theoretical support on future subway interior and exterior spaces, visual advertising and content design.

Key words: subway space, public space, visual design, media environment, media preference
