Evaluation of Transfer Space Efficiency of Metro Stations in Renovation Projects Using Virtual Wayfinding Tasks and User Satisfaction Surveys

Recently, rail transit stations have been actively integrated with the surrounding business environment in the pre-design stage, showing scale, diversity and integration. Therefore, compared with the traditional single function, the function and layout of the internal space of the rail transit station are becoming more and more complex, and the wayfinding of the passengers in its internal space is becoming more and more difficult, and they often get lost in the rail transit interchange space. Through field research, it is found that the interchange environment of urban rail transit has problems such as poor spatial orientation, dark light and vague guide signs, etc. In this paper, through the remote virtual wayfinding experimental research on metro Haidian Huangzhuang Station, Zhongguancun Station and Suzhou Street Station, we analyze the results of the wayfinding data and combine it with questionnaire surveys to set up a scientific and systematic spatial efficiency evaluation system, and ultimately summarize the characteristics of the interchange space layout and put forward the relevant optimization strategies to provide a better solution for the passengers in their internal space. Relevant optimization strategies are proposed to provide theoretical support for the establishment of metro station spatial layout evaluation system.
