Discuss the Application of Public Art in Subway Station - A Case on Lisbon Subway

With the social development, the ground traffic state is basically saturated, and the underground rail transit represented by the subway is getting more important. It is not merely the transportation junction, but also the culture express that can spread substantial information, which may display the unique urban culture, and offer aesthetic education to the public during the process of waiting for the metro. Recently, rail transit communication construction has already entered a heated development stage, and its infrastructures have already been equipped, but the construction in spiritual level is not enough. Compared to the design status of foreign subways, the difference is worth consideration. This paper aims to analyze the design technique of the public art through the status analysis of Lisbon Subway in Portugal, hoping to enlighten Chinese designers to create better public art that can be integrated into people's lives and satisfy the popular aesthetics.
