Abstract: To improve the design and construction level of Chongqing Rail Transit station wayfinding signs, investigation is carried out on the current layout situation of vertical guide sign columns of Chongqing Rail Transit station. It is found that there are problems such as unreasonable design, insufficient information, too close to the station, discontinuous setting, unreasonable installation position, occlusion or damage of information. Analysis suggests that the main reasons for these problems include not paying enough attention to national standards, lack of design and construction standards, non-professional signage enterprises participating in design and construction, lack of maintenance and management, as well as urban rail transit land-use restrictions. Improvement suggestions are put forward, including formulating wayfinding sign design and construction standards, selecting qualified design and construction units, establishing post-evaluation system.
